+
+# Testing documentation examples
+
+Good documentation oftens comes with an example of how a specific function or class should be used. 
+Each model class should contain at least one example showcasing
+how to use this model class in inference. *E.g.* the class [Wav2Vec2ForCTC](https://huggingface.co/docs/transformers/model_doc/wav2vec2#transformers.Wav2Vec2ForCTC) 
+includes an example of how to transcribe speech to text in the 
+[docstring of its forward function](https://huggingface.co/docs/transformers/model_doc/wav2vec2#transformers.Wav2Vec2ForCTC.forward).
+
+## Writing documenation examples
+
+The syntax for Example docstrings can look as follows:
+
+```
+    Example:
+
+    ```python
+    >>> from transformers import Wav2Vec2Processor, Wav2Vec2ForCTC
+    >>> from datasets import load_dataset
+    >>> import torch
+
+    >>> dataset = load_dataset("hf-internal-testing/librispeech_asr_demo", "clean", split="validation")
+    >>> dataset = dataset.sort("id")
+    >>> sampling_rate = dataset.features["audio"].sampling_rate
+
+    >>> processor = Wav2Vec2Processor.from_pretrained("facebook/wav2vec2-base-960h")
+    >>> model = Wav2Vec2ForCTC.from_pretrained("facebook/wav2vec2-base-960h")
+
+    >>> # audio file is decoded on the fly
+    >>> inputs = processor(dataset[0]["audio"]["array"], sampling_rate=sampling_rate, return_tensors="pt")
+    >>> with torch.no_grad():
+    ...     logits = model(**inputs).logits
+    >>> predicted_ids = torch.argmax(logits, dim=-1)
+
+    >>> # transcribe speech
+    >>> transcription = processor.batch_decode(predicted_ids)
+    >>> transcription[0]
+    'MISTER QUILTER IS THE APOSTLE OF THE MIDDLE CLASSES AND WE ARE GLAD TO WELCOME HIS GOSPEL'
+    ```
+```
+
+The docstring should give a minimal, clear example of how the respective model 
+is to be used in inference and also include the expected (ideally sensible)
+output.
+Often, readers will try out the example before even going through the function 
+or class definitions. Therefore it is of utmost importance that the example 
+works as expected.
+
+## Docstring testing
+
+To do so each example should be included in the doctests. 
+We use pytests' [doctest integration](https://docs.pytest.org/doctest.html) to verify that all of our examples run correctly. 
+For Transformers, the doctests are run on a daily basis via GitHub Actions as can be 
+seen [here](https://github.com/huggingface/transformers/actions/workflows/doctests.yml).
+
+To include your example in the daily doctests, you need add the filename that
+contains the example docstring to the [documentation_tests.txt](../utils/documentation_tests.txt).
+
+### For Python files
+
+You can run all the tests in the docstrings of a given file with the following command, here is how we test the modeling file of Wav2Vec2 for instance:
+
+```bash
+pytest --doctest-modules src/transformers/models/wav2vec2/modeling_wav2vec2.py -sv --doctest-continue-on-failure
+```
+
+If you want to isolate a specific docstring, just add `::` after the file name then type the whole path of the function/class/method whose docstring you want to test. For instance, here is how to just test the forward method of `Wav2Vec2ForCTC`:
+
+```bash
+pytest --doctest-modules src/transformers/models/wav2vec2/modeling_wav2vec2.py::transformers.models.wav2vec2.modeling_wav2vec2.Wav2Vec2ForCTC.forward -sv --doctest-continue-on-failure
+```
+
+### For Markdown files
+
+You will first need to run the following command (from the root of the repository) to prepare the doc file (doc-testing needs to add additional lines that we don't include in the doc source files):
+
+```bash
+python utils/prepare_for_doc_test.py src docs
+```
+
+Then you can test locally a given file with this command (here testing the quicktour):
+
+```bash
+pytest --doctest-modules docs/source/quicktour.mdx -sv --doctest-continue-on-failure --doctest-glob="*.mdx"
+```
+
+Once you're done, you can run the following command (still from the root of the repository) to undo the changes made by the first command before committing:
+
+```bash
+python utils/prepare_for_doc_test.py src docs --remove_new_line
+```
+
+### Writing doctests
+
+Here are a few tips to help you debug the doctests and make them pass:
+
+- The outputs of the code need to match the expected output **exactly**, so make sure you have the same outputs. In particular doctest will see a difference between single quotes and double quotes, or a missing parenthesis. The only exceptions to that rule are:
+  * whitespace: one give whitespace (space, tabulation, new line) is equivalent to any number of whitespace, so you can add new lines where there are spaces to make your output more readable.
+  * numerical values: you should never put more than 4 or 5 digits to expected results as different setups or library versions might get you slightly different results. `doctest` is configure to ignore any difference lower than the precision to which you wrote (so 1e-4 if you write 4 digits).
+- Don't leave a block of code that is very long to execute. If you can't make it fast, you can either not use the doctest syntax on it (so that it's ignored), or if you want to use the doctest syntax to show the results, you can add a comment `# doctest: +SKIP` at the end of the lines of code too long to execute
+- Each line of code that produces a result needs to have that result written below. You can ignore an output if you don't want to show it in your code example by adding a comment ` # doctest: +IGNORE_RESULT` at the end of the line of code produing it.

+# Distributed training with 🤗 Accelerate
+
+As models get bigger, parallelism has emerged as a strategy for training larger models on limited hardware and accelerating training speed by several orders of magnitude. At Hugging Face, we created the [🤗 Accelerate](https://huggingface.co/docs/accelerate/index.html) library to help users easily train a 🤗 Transformers model on any type of distributed setup, whether it is multiple GPU's on one machine or multiple GPU's across several machines. In this tutorial, learn how to customize your native PyTorch training loop to enable training in a distributed environment.
+
+## Setup
+
+Get started by installing 🤗 Accelerate:
+
+```bash
+pip install accelerate
+```
+
+Then import and create an [`Accelerator`](https://huggingface.co/docs/accelerate/accelerator.html#accelerate.Accelerator) object. `Accelerator` will automatically detect your type of distributed setup and initialize all the necessary components for training. You don't need to explicitly place your model on a device.
+
+```py
+>>> from accelerate import Accelerator
+
+>>> accelerator = Accelerator()
+```
+
+## Prepare to accelerate
+
+The next step is to pass all the relevant training objects to the [`prepare`](https://huggingface.co/docs/accelerate/accelerator.html#accelerate.Accelerator.prepare) method. This includes your training and evaluation DataLoaders, a model and an optimizer:
+
+```py
+>>> train_dataloader, eval_dataloader, model, optimizer = accelerator.prepare(
+...     train_dataloader, eval_dataloader, model, optimizer
+... )
+```
+
+## Backward
+
+The last addition is to replace the typical `loss.backward()` in your training loop with 🤗 Accelerate's [`backward`](https://huggingface.co/docs/accelerate/accelerator.html#accelerate.Accelerator.backward) method:
+
+```py
+>>> for epoch in range(num_epochs):
+...     for batch in train_dataloader:
+...         outputs = model(**batch)
+...         loss = outputs.loss
+...         accelerator.backward(loss)
+
+...         optimizer.step()
+...         lr_scheduler.step()
+...         optimizer.zero_grad()
+...         progress_bar.update(1)
+```
+
+As you can see in the following code, you only need to add four additional lines of code to your training loop to enable distributed training!
+
+```diff
++ from accelerate import Accelerator
+  from transformers import AdamW, AutoModelForSequenceClassification, get_scheduler
+
++ accelerator = Accelerator()
+
+  model = AutoModelForSequenceClassification.from_pretrained(checkpoint, num_labels=2)
+  optimizer = AdamW(model.parameters(), lr=3e-5)
+
+- device = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")
+- model.to(device)
+
++ train_dataloader, eval_dataloader, model, optimizer = accelerator.prepare(
++     train_dataloader, eval_dataloader, model, optimizer
++ )
+
+  num_epochs = 3
+  num_training_steps = num_epochs * len(train_dataloader)
+  lr_scheduler = get_scheduler(
+      "linear",
+      optimizer=optimizer,
+      num_warmup_steps=0,
+      num_training_steps=num_training_steps
+  )
+
+  progress_bar = tqdm(range(num_training_steps))
+
+  model.train()
+  for epoch in range(num_epochs):
+      for batch in train_dataloader:
+-         batch = {k: v.to(device) for k, v in batch.items()}
+          outputs = model(**batch)
+          loss = outputs.loss
+-         loss.backward()
++         accelerator.backward(loss)
+
+          optimizer.step()
+          lr_scheduler.step()
+          optimizer.zero_grad()
+          progress_bar.update(1)
+```
+
+## Train
+
+Once you've added the relevant lines of code, launch your training in a script or a notebook like Colaboratory.
+
+### Train with a script
+
+If you are running your training from a script, run the following command to create and save a configuration file:
+
+```bash
+accelerate config
+```
+
+Then launch your training with:
+
+```bash
+accelerate launch train.py
+```
+
+### Train with a notebook
+
+🤗 Accelerate can also run in a notebook if you're planning on using Colaboratory's TPUs. Wrap all the code responsible for training in a function, and pass it to `notebook_launcher`:
+
+```py
+>>> from accelerate import notebook_launcher
+
+>>> notebook_launcher(training_function)
+```
+
+For more information about 🤗 Accelerate and it's rich features, refer to the [documentation](https://huggingface.co/docs/accelerate/index.html).

+# How to add a pipeline to 🤗 Transformers?
+
+First and foremost, you need to decide the raw entries the pipeline will be able to take. It can be strings, raw bytes,
+dictionaries or whatever seems to be the most likely desired input. Try to keep these inputs as pure Python as possible
+as it makes compatibility easier (even through other languages via JSON). Those will be the `inputs` of the
+pipeline (`preprocess`).
+
+Then define the `outputs`. Same policy as the `inputs`. The simpler, the better. Those will be the outputs of
+`postprocess` method.
+
+Start by inheriting the base class `Pipeline`. with the 4 methods needed to implement `preprocess`,
+`_forward`, `postprocess` and `_sanitize_parameters`.
+
+
+```python
+from transformers import Pipeline
+
+
+class MyPipeline(Pipeline):
+    def _sanitize_parameters(self, **kwargs):
+        preprocess_kwargs = {}
+        if "maybe_arg" in kwargs:
+            preprocess_kwargs["maybe_arg"] = kwargs["maybe_arg"]
+        return preprocess_kwargs, {}, {}
+
+    def preprocess(self, inputs, maybe_arg=2):
+        model_input = Tensor(inputs["input_ids"])
+        return {"model_input": model_input}
+
+    def _forward(self, model_inputs):
+        # model_inputs == {"model_input": model_input}
+        outputs = self.model(**model_inputs)
+        # Maybe {"logits": Tensor(...)}
+        return outputs
+
+    def postprocess(self, model_outputs):
+        best_class = model_outputs["logits"].softmax(-1)
+        return best_class
+```
+
+The structure of this breakdown is to support relatively seamless support for CPU/GPU, while supporting doing
+pre/postprocessing on the CPU on different threads
+
+`preprocess` will take the originally defined inputs, and turn them into something feedable to the model. It might
+contain more information and is usually a `Dict`.
+
+`_forward` is the implementation detail and is not meant to be called directly. `forward` is the preferred
+called method as it contains safeguards to make sure everything is working on the expected device. If anything is
+linked to a real model it belongs in the `_forward` method, anything else is in the preprocess/postprocess.
+
+`postprocess` methods will take the output of `_forward` and turn it into the final output that were decided
+earlier.
+
+`_sanitize_parameters` exists to allow users to pass any parameters whenever they wish, be it at initialization
+time `pipeline(...., maybe_arg=4)` or at call time `pipe = pipeline(...); output = pipe(...., maybe_arg=4)`.
+
+The returns of `_sanitize_parameters` are the 3 dicts of kwargs that will be passed directly to `preprocess`,
+`_forward` and `postprocess`. Don't fill anything if the caller didn't call with any extra parameter. That
+allows to keep the default arguments in the function definition which is always more "natural".
+
+A classic example would be a `top_k` argument in the post processing in classification tasks.
+
+```python
+>>> pipe = pipeline("my-new-task")
+>>> pipe("This is a test")
+[{"label": "1-star", "score": 0.8}, {"label": "2-star", "score": 0.1}, {"label": "3-star", "score": 0.05}
+{"label": "4-star", "score": 0.025}, {"label": "5-star", "score": 0.025}]
+
+>>> pipe("This is a test", top_k=2)
+[{"label": "1-star", "score": 0.8}, {"label": "2-star", "score": 0.1}]
+```
+
+In order to achieve that, we'll update our `postprocess` method with a default parameter to `5`. and edit
+`_sanitize_parameters` to allow this new parameter.
+
+
+```python
+def postprocess(self, model_outputs, top_k=5):
+    best_class = model_outputs["logits"].softmax(-1)
+    # Add logic to handle top_k
+    return best_class
+
+
+def _sanitize_parameters(self, **kwargs):
+    preprocess_kwargs = {}
+    if "maybe_arg" in kwargs:
+        preprocess_kwargs["maybe_arg"] = kwargs["maybe_arg"]
+
+    postprocess_kwargs = {}
+    if "top_k" in kwargs:
+        preprocess_kwargs["top_k"] = kwargs["top_k"]
+    return preprocess_kwargs, {}, postprocess_kwargs
+```
+
+Try to keep the inputs/outputs very simple and ideally JSON-serializable as it makes the pipeline usage very easy
+without requiring users to understand new kind of objects. It's also relatively common to support many different types
+of arguments for ease of use (audio files, can be filenames, URLs or pure bytes)
+
+
+
+## Adding it to the list of supported tasks
+
+Go to `src/transformers/pipelines/__init__.py` and fill in `SUPPORTED_TASKS` with your newly created pipeline.
+If possible it should provide a default model.
+
+## Adding tests
+
+Create a new file `tests/test_pipelines_MY_PIPELINE.py` with example with the other tests.
+
+The `run_pipeline_test` function will be very generic and run on small random models on every possible
+architecture as defined by `model_mapping` and `tf_model_mapping`.
+
+This is very important to test future compatibility, meaning if someone adds a new model for
+`XXXForQuestionAnswering` then the pipeline test will attempt to run on it. Because the models are random it's
+impossible to check for actual values, that's why There is a helper `ANY` that will simply attempt to match the
+output of the pipeline TYPE.
+
+You also *need* to implement 2 (ideally 4) tests.
+
+- `test_small_model_pt` : Define 1 small model for this pipeline (doesn't matter if the results don't make sense)
+  and test the pipeline outputs. The results should be the same as `test_small_model_tf`.

+# Load pretrained instances with an AutoClass
+
+With so many different Transformer architectures, it can be challenging to create one for your checkpoint. As a part of 🤗 Transformers core philosophy to make the library easy, simple and flexible to use, an `AutoClass` automatically infer and load the correct architecture from a given checkpoint. The `from_pretrained` method lets you quickly load a pretrained model for any architecture so you don't have to devote time and resources to train a model from scratch. Producing this type of checkpoint-agnostic code means if your code works for one checkpoint, it will work with another checkpoint - as long as it was trained for a similar task - even if the architecture is different.
+
+<Tip>
+
+Remember, architecture refers to the skeleton of the model and checkpoints are the weights for a given architecture. For example, [BERT](https://huggingface.co/bert-base-uncased) is an architecture, while `bert-base-uncased` is a checkpoint. Model is a general term that can mean either architecture or checkpoint.
+
+</Tip>
+
+In this tutorial, learn to:
+
+* Load a pretrained tokenizer.
+* Load a pretrained feature extractor.
+* Load a pretrained processor.
+* Load a pretrained model.
+
+## AutoTokenizer
+
+Nearly every NLP task begins with a tokenizer. A tokenizer converts your input into a format that can be processed by the model.
+
+Load a tokenizer with [`AutoTokenizer.from_pretrained`]:
+
+```py
+>>> from transformers import AutoTokenizer
+
+>>> tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
+```
+
+Then tokenize your input as shown below:
+
+```py
+>>> sequence = "In a hole in the ground there lived a hobbit."
+>>> print(tokenizer(sequence))
+{'input_ids': [101, 1999, 1037, 4920, 1999, 1996, 2598, 2045, 2973, 1037, 7570, 10322, 4183, 1012, 102], 
+ 'token_type_ids': [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], 
+ 'attention_mask': [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]}
+```
+
+## AutoFeatureExtractor
+
+For audio and vision tasks, a feature extractor processes the audio signal or image into the correct input format.
+
+Load a feature extractor with [`AutoFeatureExtractor.from_pretrained`]:
+
+```py
+>>> from transformers import AutoFeatureExtractor
+
+>>> feature_extractor = AutoFeatureExtractor.from_pretrained(
+...     "ehcalabres/wav2vec2-lg-xlsr-en-speech-emotion-recognition"
+... )
+```
+
+## AutoProcessor
+
+Multimodal tasks require a processor that combines two types of preprocessing tools. For example, the [LayoutLMV2](model_doc/layoutlmv2) model requires a feature extractor to handle images and a tokenizer to handle text; a processor combines both of them.
+
+Load a processor with [`AutoProcessor.from_pretrained`]:
+
+```py
+>>> from transformers import AutoProcessor
+
+>>> processor = AutoProcessor.from_pretrained("microsoft/layoutlmv2-base-uncased")
+```
+
+## AutoModel
+
+Finally, the `AutoModelFor` classes let you load a pretrained model for a given task (see [here](model_doc/auto) for a complete list of available tasks). For example, load a model for sequence classification with [`AutoModelForSequenceClassification.from_pretrained`]:
+
+```py
+>>> from transformers import AutoModelForSequenceClassification
+
+>>> model = AutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased")
+===PT-TF-SPLIT===
+>>> from transformers import TFAutoModelForSequenceClassification
+
+>>> model = TFAutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased")
+```
+
+Easily reuse the same checkpoint to load an architecture for a different task:
+
+```py
+>>> from transformers import AutoModelForTokenClassification
+
+>>> model = AutoModelForTokenClassification.from_pretrained("distilbert-base-uncased")
+===PT-TF-SPLIT===
+>>> from transformers import TFAutoModelForTokenClassification
+
+>>> model = TFAutoModelForTokenClassification.from_pretrained("distilbert-base-uncased")
+```
+
+Generally, we recommend using the `AutoTokenizer` class and the `AutoModelFor` class to load pretrained instances of models. This will ensure you load the correct architecture every time. In the next [tutorial](preprocessing), learn how to use your newly loaded tokenizer, feature extractor and processor to preprocess a dataset for fine-tuning.

+# Converting Tensorflow Checkpoints
+
+A command-line interface is provided to convert original Bert/GPT/GPT-2/Transformer-XL/XLNet/XLM checkpoints to models
+that can be loaded using the `from_pretrained` methods of the library.
+
+<Tip>
+
+Since 2.3.0 the conversion script is now part of the transformers CLI (**transformers-cli**) available in any
+transformers >= 2.3.0 installation.
+
+The documentation below reflects the **transformers-cli convert** command format.
+
+</Tip>
+
+## BERT
+
+You can convert any TensorFlow checkpoint for BERT (in particular [the pre-trained models released by Google](https://github.com/google-research/bert#pre-trained-models)) in a PyTorch save file by using the
+[convert_bert_original_tf_checkpoint_to_pytorch.py](https://github.com/huggingface/transformers/tree/master/src/transformers/models/bert/convert_bert_original_tf_checkpoint_to_pytorch.py) script.
+
+This CLI takes as input a TensorFlow checkpoint (three files starting with `bert_model.ckpt`) and the associated
+configuration file (`bert_config.json`), and creates a PyTorch model for this configuration, loads the weights from
+the TensorFlow checkpoint in the PyTorch model and saves the resulting model in a standard PyTorch save file that can
+be imported using `from_pretrained()` (see example in [quicktour](quicktour) , [run_glue.py](https://github.com/huggingface/transformers/tree/master/examples/pytorch/text-classification/run_glue.py) ).
+
+You only need to run this conversion script **once** to get a PyTorch model. You can then disregard the TensorFlow
+checkpoint (the three files starting with `bert_model.ckpt`) but be sure to keep the configuration file (\
+`bert_config.json`) and the vocabulary file (`vocab.txt`) as these are needed for the PyTorch model too.
+
+To run this specific conversion script you will need to have TensorFlow and PyTorch installed (`pip install tensorflow`). The rest of the repository only requires PyTorch.
+
+Here is an example of the conversion process for a pre-trained `BERT-Base Uncased` model:
+
+```bash
+export BERT_BASE_DIR=/path/to/bert/uncased_L-12_H-768_A-12
+
+transformers-cli convert --model_type bert \
+  --tf_checkpoint $BERT_BASE_DIR/bert_model.ckpt \
+  --config $BERT_BASE_DIR/bert_config.json \
+  --pytorch_dump_output $BERT_BASE_DIR/pytorch_model.bin
+```
+
+You can download Google's pre-trained models for the conversion [here](https://github.com/google-research/bert#pre-trained-models).
+
+## ALBERT
+
+Convert TensorFlow model checkpoints of ALBERT to PyTorch using the
+[convert_albert_original_tf_checkpoint_to_pytorch.py](https://github.com/huggingface/transformers/tree/master/src/transformers/models/albert/convert_albert_original_tf_checkpoint_to_pytorch.py) script.
+
+The CLI takes as input a TensorFlow checkpoint (three files starting with `model.ckpt-best`) and the accompanying
+configuration file (`albert_config.json`), then creates and saves a PyTorch model. To run this conversion you will
+need to have TensorFlow and PyTorch installed.
+
+Here is an example of the conversion process for the pre-trained `ALBERT Base` model:
+
+```bash
+export ALBERT_BASE_DIR=/path/to/albert/albert_base
+
+transformers-cli convert --model_type albert \
+  --tf_checkpoint $ALBERT_BASE_DIR/model.ckpt-best \
+  --config $ALBERT_BASE_DIR/albert_config.json \
+  --pytorch_dump_output $ALBERT_BASE_DIR/pytorch_model.bin
+```
+
+You can download Google's pre-trained models for the conversion [here](https://github.com/google-research/albert#pre-trained-models).
+
+## OpenAI GPT
+
+Here is an example of the conversion process for a pre-trained OpenAI GPT model, assuming that your NumPy checkpoint
+save as the same format than OpenAI pretrained model (see [here](https://github.com/openai/finetune-transformer-lm)\

+
+```bash

+
+## OpenAI GPT-2
+
+Here is an example of the conversion process for a pre-trained OpenAI GPT-2 model (see [here](https://github.com/openai/gpt-2))
+
+```bash

+# Create a custom model
+
+An [`AutoClass`](model_doc/auto) automatically infers the model architecture and downloads pretrained configuration and weights. Generally, we recommend using an `AutoClass` to produce checkpoint-agnostic code. But users who want more control over specific model parameters can create a custom 🤗 Transformers model from just a few base classes. This could be particularly useful for anyone who is interested in studying, training or experimenting with a 🤗 Transformers model. In this guide, dive deeper into creating a custom model without an `AutoClass`. Learn how to:
+
+- Load and customize a model configuration.
+- Create a model architecture.
+- Create a slow and fast tokenizer for text.
+- Create a feature extractor for audio or image tasks.
+- Create a processor for multimodal tasks.
+
+## Configuration
+
+A [configuration](main_classes/configuration) refers to a model's specific attributes. Each model configuration has different attributes; for instance, all NLP models have the `hidden_size`, `num_attention_heads`, `num_hidden_layers` and `vocab_size` attributes in common. These attributes specify the number of attention heads or hidden layers to construct a model with.
+
+Get a closer look at [DistilBERT](model_doc/distilbert) by accessing [`DistilBertConfig`] to inspect it's attributes:
+
+```py
+>>> from transformers import DistilBertConfig
+
+>>> config = DistilBertConfig()
+>>> print(config)
+DistilBertConfig {
+  "activation": "gelu",
+  "attention_dropout": 0.1,
+  "dim": 768,
+  "dropout": 0.1,
+  "hidden_dim": 3072,
+  "initializer_range": 0.02,
+  "max_position_embeddings": 512,
+  "model_type": "distilbert",
+  "n_heads": 12,
+  "n_layers": 6,
+  "pad_token_id": 0,
+  "qa_dropout": 0.1,
+  "seq_classif_dropout": 0.2,
+  "sinusoidal_pos_embds": false,
+  "transformers_version": "4.16.2",
+  "vocab_size": 30522
+}
+```
+
+[`DistilBertConfig`] displays all the default attributes used to build a base [`DistilBertModel`]. All attributes are customizable, creating space for experimentation. For example, you can customize a default model to:
+
+- Try a different activation function with the `activation` parameter.
+- Use a higher dropout ratio for the attention probabilities with the `attention_dropout` parameter.
+
+```py
+>>> my_config = DistilBertConfig(activation="relu", attention_dropout=0.4)
+>>> print(my_config)
+DistilBertConfig {
+  "activation": "relu",
+  "attention_dropout": 0.4,
+  "dim": 768,
+  "dropout": 0.1,
+  "hidden_dim": 3072,
+  "initializer_range": 0.02,
+  "max_position_embeddings": 512,
+  "model_type": "distilbert",
+  "n_heads": 12,
+  "n_layers": 6,
+  "pad_token_id": 0,
+  "qa_dropout": 0.1,
+  "seq_classif_dropout": 0.2,
+  "sinusoidal_pos_embds": false,
+  "transformers_version": "4.16.2",
+  "vocab_size": 30522
+}
+```
+
+Pretrained model attributes can be modified in the [`~PretrainedConfig.from_pretrained`] function:
+
+```py
+>>> my_config = DistilBertConfig.from_pretrained("distilbert-base-uncased", activation="relu", attention_dropout=0.4)
+```
+
+Once you are satisfied with your model configuration, you can save it with [`~PretrainedConfig.save_pretrained`]. Your configuration file is stored as a JSON file in the specified save directory:
+
+```py
+>>> my_config.save_pretrained(save_directory="./your_model_save_path")
+```
+
+To reuse the configuration file, load it with [`~PretrainedConfig.from_pretrained`]:
+
+```py
+>>> my_config = DistilBertConfig.from_pretrained("./your_model_save_path/my_config.json")
+```
+
+<Tip>
+
+You can also save your configuration file as a dictionary or even just the difference between your custom configuration attributes and the default configuration attributes! See the [configuration](main_classes/configuration) documentation for more details.
+
+</Tip>
+
+## Model
+
+The next step is to create a [model](main_classes/models). The model - also loosely referred to as the architecture - defines what each layer is doing and what operations are happening. Attributes like `num_hidden_layers` from the configuration are used to define the architecture. Every model shares the base class [`PreTrainedModel`] and a few common methods like resizing input embeddings and pruning self-attention heads. In addition, all models are also either a [`torch.nn.Module`](https://pytorch.org/docs/stable/generated/torch.nn.Module.html), [`tf.keras.Model`](https://www.tensorflow.org/api_docs/python/tf/keras/Model) or [`flax.linen.Module`](https://flax.readthedocs.io/en/latest/flax.linen.html#module) subclass. This means models are compatible with each of their respective framework's usage.
+
+Load your custom configuration attributes into the model:
+
+```py
+>>> from transformers import DistilBertModel
+
+>>> my_config = DistilBertConfig.from_pretrained("./your_model_save_path/my_config.json")
+>>> model = DistilBertModel(my_config)
+===PT-TF-SPLIT===
+>>> from transformers import TFDistilBertModel
+
+>>> my_config = DistilBertConfig.from_pretrained("./your_model_save_path/my_config.json")
+>>> tf_model = TFDistilBertModel(my_config)
+```
+
+This creates a model with random values instead of pretrained weights. You won't be able to use this model for anything useful yet until you train it. Training is a costly and time-consuming process. It is generally better to use a pretrained model to obtain better results faster, while using only a fraction of the resources required for training.
+
+Create a pretrained model with [`~PreTrainedModel.from_pretrained`]:
+
+```py
+>>> model = DistilBertModel.from_pretrained("distilbert-base-uncased")
+===PT-TF-SPLIT===
+>>> tf_model = TFDistilBertModel.from_pretrained("distilbert-base-uncased")
+```
+
+When you load pretrained weights, the default model configuration is automatically loaded if the model is provided by 🤗 Transformers. However, you can still replace - some or all of - the default model configuration attributes with your own if you'd like:
+
+```py
+>>> model = DistilBertModel.from_pretrained("distilbert-base-uncased", config=my_config)
+===PT-TF-SPLIT===
+>>> tf_model = TFDistilBertModel.from_pretrained("distilbert-base-uncased", config=my_config)
+```
+
+### Model heads
+
+At this point, you have a base DistilBERT model which outputs the *hidden states*. The hidden states are passed as inputs to a model head to produce the final output. 🤗 Transformers provides a different model head for each task as long as a model supports the task (i.e., you can't use DistilBERT for a sequence-to-sequence task like translation).
+
+For example, [`DistilBertForSequenceClassification`] is a base DistilBERT model with a sequence classification head. The sequence classification head is a linear layer on top of the pooled outputs.
+
+```py
+>>> from transformers import DistilBertForSequenceClassification
+
+>>> model = DistilBertForSequenceClassification.from_pretrained("distilbert-base-uncased")
+===PT-TF-SPLIT===
+>>> from transformers import TFDistilBertForSequenceClassification
+
+>>> tf_model = TFDistilBertForSequenceClassification.from_pretrained("distilbert-base-uncased")
+```
+
+Easily reuse this checkpoint for another task by switching to a different model head. For a question answering task, you would use the [`DistilBertForQuestionAnswering`] model head. The question answering head is similar to the sequence classification head except it is a linear layer on top of the hidden states output.
+
+```py
+>>> from transformers import DistilBertForQuestionAnswering
+
+>>> model = DistilBertForQuestionAnswering.from_pretrained("distilbert-base-uncased")
+===PT-TF-SPLIT===
+>>> from transformers import TFDistilBertForQuestionAnswering
+
+>>> tf_model = TFDistilBertForQuestionAnswering.from_pretrained("distilbert-base-uncased")
+```
+
+## Tokenizer
+
+The last base class you need before using a model for textual data is a [tokenizer](main_classes/tokenizer) to convert raw text to tensors. There are two types of tokenizers you can use with 🤗 Transformers:
+
+- [`PreTrainedTokenizer`]: a Python implementation of a tokenizer.
+- [`PreTrainedTokenizerFast`]: a tokenizer from our Rust-based [🤗 Tokenizer](https://huggingface.co/docs/tokenizers/python/latest/) library. This tokenizer type is significantly faster - especially during batch tokenization - due to it's Rust implementation. The fast tokenizer also offers additional methods like *offset mapping* which maps tokens to their original words or characters.
+
+Both tokenizers support common methods such as encoding and decoding, adding new tokens, and managing special tokens.
+
+<Tip warning={true}>
+
+Not every model supports a fast tokenizer. Take a look at this [table](index#supported-frameworks) to check if a model has fast tokenizer support.
+
+</Tip>
+
+If you trained your own tokenizer, you can create one from your *vocabulary* file:
+
+```py
+>>> from transformers import DistilBertTokenizer
+
+>>> my_tokenizer = DistilBertTokenizer(vocab_file="my_vocab_file.txt", do_lower_case=False, padding_side="left")
+```
+
+It is important to remember the vocabulary from a custom tokenizer will be different from the vocabulary generated by a pretrained model's tokenizer. You need to use a pretrained model's vocabulary if you are using a pretrained model, otherwise the inputs won't make sense. Create a tokenizer with a pretrained model's vocabulary with the [`DistilBertTokenizer`] class:
+
+```py
+>>> from transformers import DistilBertTokenizer
+
+>>> slow_tokenizer = DistilBertTokenizer.from_pretrained("distilbert-base-uncased")
+```
+
+Create a fast tokenizer with the [`DistilBertTokenizerFast`] class:
+
+```py
+>>> from transformers import DistilBertTokenizerFast
+
+>>> fast_tokenizer = DistilBertTokenizerFast.from_pretrained("distilbert-base-uncased")
+```
+
+<Tip>
+
+By default, [`AutoTokenizer`] will try to load a fast tokenizer. You can disable this behavior by setting `use_fast=False` in `from_pretrained`.
+
+</Tip>
+
+## Feature Extractor
+
+A feature extractor processes audio or image inputs. It inherits from the base [`~feature_extraction_utils.FeatureExtractionMixin`] class, and may also inherit from the [`ImageFeatureExtractionMixin`] class for processing image features or the [`SequenceFeatureExtractor`] class for processing audio inputs.
+
+Depending on whether you are working on an audio or vision task, create a feature extractor associated with the model you're using. For example, create a default [`ViTFeatureExtractor`] if you are using [ViT](model_doc/vit) for image classification:
+
+```py
+>>> from transformers import ViTFeatureExtractor
+
+>>> vit_extractor = ViTFeatureExtractor()
+>>> print(vit_extractor)
+ViTFeatureExtractor {
+  "do_normalize": true,
+  "do_resize": true,
+  "feature_extractor_type": "ViTFeatureExtractor",
+  "image_mean": [
+    0.5,
+    0.5,
+    0.5
+  ],
+  "image_std": [
+    0.5,
+    0.5,
+    0.5
+  ],
+  "resample": 2,
+  "size": 224
+}
+```
+
+<Tip>
+
+If you aren't looking for any customization, just use the `from_pretrained` method to load a model's default feature extractor parameters.
+
+</Tip>
+
+Modify any of the [`ViTFeatureExtractor`] parameters to create your custom feature extractor:
+
+```py
+>>> from transformers import ViTFeatureExtractor
+
+>>> my_vit_extractor = ViTFeatureExtractor(resample="PIL.Image.BOX", do_normalize=False, image_mean=[0.3, 0.3, 0.3])
+>>> print(my_vit_extractor)
+ViTFeatureExtractor {
+  "do_normalize": false,
+  "do_resize": true,
+  "feature_extractor_type": "ViTFeatureExtractor",
+  "image_mean": [
+    0.3,
+    0.3,
+    0.3
+  ],
+  "image_std": [
+    0.5,
+    0.5,
+    0.5
+  ],
+  "resample": "PIL.Image.BOX",
+  "size": 224
+}
+```
+
+For audio inputs, you can create a [`Wav2Vec2FeatureExtractor`] and customize the parameters in a similar way:
+
+```py
+>>> from transformers import Wav2Vec2FeatureExtractor
+
+>>> w2v2_extractor = Wav2Vec2FeatureExtractor()
+>>> print(w2v2_extractor)
+Wav2Vec2FeatureExtractor {
+  "do_normalize": true,
+  "feature_extractor_type": "Wav2Vec2FeatureExtractor",
+  "feature_size": 1,
+  "padding_side": "right",
+  "padding_value": 0.0,
+  "return_attention_mask": false,
+  "sampling_rate": 16000
+}
+```
+
+## Processor
+
+For models that support multimodal tasks, 🤗 Transformers offers a processor class that conveniently wraps a feature extractor and tokenizer into a single object. For example, let's use the [`Wav2Vec2Processor`] for an automatic speech recognition task (ASR). ASR transcribes audio to text, so you will need a feature extractor and a tokenizer.
+
+Create a feature extractor to handle the audio inputs:
+
+```py
+>>> from transformers import Wav2Vec2FeatureExtractor
+
+>>> feature_extractor = Wav2Vec2FeatureExtractor(padding_value=1.0, do_normalize=True)
+```
+
+Create a tokenizer to handle the text inputs:
+
+```py
+>>> from transformers import Wav2Vec2CTCTokenizer
+
+>>> tokenizer = Wav2Vec2CTCTokenizer(vocab_file="my_vocab_file.txt")
+```
+
+Combine the feature extractor and tokenizer in [`Wav2Vec2Processor`]:
+
+```py
+>>> from transformers import Wav2Vec2Processor
+
+>>> processor = Wav2Vec2Processor(feature_extractor=feature_extractor, tokenizer=tokenizer)
+```
+
+With two basic classes - configuration and model - and an additional preprocessing class (tokenizer, feature extractor, or processor), you can create any of the models supported by 🤗 Transformers. Each of these base classes are configurable, allowing you to use the specific attributes you want. You can easily setup a model for training or modify an existing pretrained model to fine-tune.

+
+# Sharing custom models
+
+The 🤗 Transformers library is designed to be easily extensible. Every model is fully coded in a given subfolder
+of the repository with no abstraction, so you can easily copy a modeling file and tweak it to your needs.
+
+If you are writing a brand new model, it might be easier to start from scratch. In this tutorial, we will show you
+how to write a custom model and its configuration so it can be used inside Transformers, and how you can share it
+with the community (with the code it relies on) so that anyone can use it, even if it's not present in the 🤗
+Transformers library.
+
+We will illustrate all of this on a ResNet model, by wrapping the ResNet class of the
+[timm library](https://github.com/rwightman/pytorch-image-models/tree/master/timm) into a [`PreTrainedModel`].
+
+## Writing a custom configuration
+
+Before we dive into the model, let's first write its configuration. The configuration of a model is an object that
+will contain all the necessary information to build the model. As we will see in the next section, the model can only
+take a `config` to be initialized, so we really need that object to be as complete as possible.
+
+In our example, we will take a couple of arguments of the ResNet class that we might want to tweak. Different
+configurations will then give us the different types of ResNets that are possible. We then just store those arguments,
+after checking the validity of a few of them.
+
+```python
+from transformers import PretrainedConfig
+from typing import List
+
+
+class ResnetConfig(PretrainedConfig):
+    model_type = "resnet"
+
+    def __init__(
+        self,
+        block_type="bottleneck",
+        layers: List[int] = [3, 4, 6, 3],
+        num_classes: int = 1000,
+        input_channels: int = 3,
+        cardinality: int = 1,
+        base_width: int = 64,
+        stem_width: int = 64,
+        stem_type: str = "",
+        avg_down: bool = False,
+        **kwargs,
+    ):
+        if block_type not in ["basic", "bottleneck"]:
+            raise ValueError(f"`block` must be 'basic' or bottleneck', got {block}.")
+        if stem_type not in ["", "deep", "deep-tiered"]:
+            raise ValueError(f"`stem_type` must be '', 'deep' or 'deep-tiered', got {block}.")
+
+        self.block_type = block_type
+        self.layers = layers
+        self.num_classes = num_classes
+        self.input_channels = input_channels
+        self.cardinality = cardinality
+        self.base_width = base_width
+        self.stem_width = stem_width
+        self.stem_type = stem_type
+        self.avg_down = avg_down
+        super().__init__(**kwargs)
+```
+
+The three important things to remember when writing you own configuration are the following:
+- you have to inherit from `PretrainedConfig`,
+- the `__init__` of your `PretrainedConfig` must accept any kwargs,
+- those `kwargs` need to be passed to the superclass `__init__`.
+
+The inheritance is to make sure you get all the functionality from the 🤗 Transformers library, while the two other
+constraints come from the fact a `PretrainedConfig` has more fields than the ones you are setting. When reloading a
+config with the `from_pretrained` method, those fields need to be accepted by your config and then sent to the
+superclass.
+
+Defining a `model_type` for your configuration (here `model_type="resnet"`) is not mandatory, unless you want to
+register your model with the auto classes (see last section).
+
+With this done, you can easily create and save your configuration like you would do with any other model config of the
+library. Here is how we can create a resnet50d config and save it:
+
+```py
+resnet50d_config = ResnetConfig(block_type="bottleneck", stem_width=32, stem_type="deep", avg_down=True)
+resnet50d_config.save_pretrained("custom-resnet")
+```
+
+This will save a file named `config.json` inside the folder `custom-resnet`. You can then reload your config with the
+`from_pretrained` method:
+
+```py
+resnet50d_config = ResnetConfig.from_pretrained("custom-resnet")
+```
+
+You can also use any other method of the [`PretrainedConfig`] class, like [`~PretrainedConfig.push_to_hub`] to
+directly upload your config to the Hub.
+
+## Writing a custom model
+
+Now that we have our ResNet configuration, we can go on writing the model. We will actually write two: one that
+extracts the hidden features from a batch of images (like [`BertModel`]) and one that is suitable for image
+classification (like [`BertModelForSequenceClassification`]).
+
+As we mentioned before, we'll only write a loose wrapper of the model to keep it simple for this example. The only
+thing we need to do before writing this class is a map between the block types and actual block classes. Then the
+model is defined from the configuration by passing everything to the `ResNet` class:
+
+```py
+from transformers import PreTrainedModel
+from timm.models.resnet import BasicBlock, Bottleneck, ResNet
+from .configuration_resnet import ResnetConfig
+
+
+BLOCK_MAPPING = {"basic": BasicBlock, "bottleneck": Bottleneck}
+
+
+class ResnetModel(PreTrainedModel):
+    config_class = ResnetConfig
+
+    def __init__(self, config):
+        super().__init__(config)
+        block_layer = BLOCK_MAPPING[config.block_type]
+        self.model = ResNet(
+            block_layer,
+            config.layers,
+            num_classes=config.num_classes,
+            in_chans=config.input_channels,
+            cardinality=config.cardinality,
+            base_width=config.base_width,
+            stem_width=config.stem_width,
+            stem_type=config.stem_type,
+            avg_down=config.avg_down,
+        )
+
+    def forward(self, tensor):
+        return self.model.forward_features(tensor)
+```
+
+For the model that will classify images, we just change the forward method:
+
+```py
+class ResnetModelForImageClassification(PreTrainedModel):
+    config_class = ResnetConfig
+
+    def __init__(self, config):
+        super().__init__(config)
+        block_layer = BLOCK_MAPPING[config.block_type]
+        self.model = ResNet(
+            block_layer,
+            config.layers,
+            num_classes=config.num_classes,
+            in_chans=config.input_channels,
+            cardinality=config.cardinality,
+            base_width=config.base_width,
+            stem_width=config.stem_width,
+            stem_type=config.stem_type,
+            avg_down=config.avg_down,
+        )
+
+    def forward(self, tensor, labels=None):
+        logits = self.model(tensor)
+        if labels is not None:
+            loss = torch.nn.cross_entropy(logits, labels)
+            return {"loss": loss, "logits": logits}
+        return {"logits": logits}
+```
+
+In both cases, notice how we inherit from `PreTrainedModel` and call the superclass initialization with the `config`
+(a bit like when you write a regular `torch.nn.Module`). The line that sets the `config_class` is not mandatory, unless
+you want to register your model with the auto classes (see last section).
+
+<Tip>
+
+If your model is very similar to a model inside the library, you can re-use the same configuration as this model.
+
+</Tip>
+
+You can have your model return anything you want, but returning a dictionary like we did for
+`ResnetModelForImageClassification`, with the loss included when labels are passed, will make your model directly
+usable inside the [`Trainer`] class. Using another output format is fine as long as you are planning on using your own
+training loop or another library for training.
+
+Now that we have our model class, let's create one:
+
+```py
+resnet50d = ResnetModelForImageClassification(resnet50d_config)
+```
+
+Again, you can use any of the methods of [`PreTrainedModel`], like [`~PreTrainedModel.save_pretrained`] or
+[`~PreTrainedModel.push_to_hub`]. We will use the second in the next section, and see how to push the model weights
+with the code of our model. But first, let's load some pretrained weights inside our model.
+
+In your own use case, you will probably be training your custom model on your own data. To go fast for this tutorial,
+we will use the pretrained version of the resnet50d. Since our model is just a wrapper around it, it's going to be
+easy to transfer those weights:
+
+```py
+import timm
+
+pretrained_model = timm.create_model("resnet50d", pretrained=True)
+resnet50d.model.load_state_dict(pretrained_model.state_dict())
+```
+
+Now let's see how to make sure that when we do [`~PreTrainedModel.save_pretrained`] or [`~PreTrainedModel.push_to_hub`], the
+code of the model is saved.
+
+## Sending the code to the Hub
+
+<Tip warning={true}>
+
+This API is experimental and may have some slight breaking changes in the next releases.
+
+</Tip>
+
+First, make sure your model is fully defined in a `.py` file. It can rely on relative imports to some other files as
+long as all the files are in the same directory (we don't support submodules for this feature yet). For our example,
+we'll define a `modeling_resnet.py` file and a `configuration_resnet.py` file in a folder of the current working
+directory named `resnet_model`. The configuration file contains the code for `ResnetConfig` and the modeling file
+contains the code of `ResnetModel` and `ResnetModelForImageClassification`.
+
+```
+.
+└── resnet_model
+    ├── __init__.py
+    ├── configuration_resnet.py
+    └── modeling_resnet.py
+```
+
+The `__init__.py` can be empty, it's just there so that Python detects `resnet_model` can be use as a module.
+
+<Tip warning={true}>
+
+If copying a modeling files from the library, you will need to replace all the relative imports at the top of the file
+to import from the `transformers` package.
+
+</Tip>
+
+Note that you can re-use (or subclass) an existing configuration/model.
+
+To share your model with the community, follow those steps: first import the ResNet model and config from the newly
+created files:
+
+```py
+from resnet_model.configuration_resnet import ResnetConfig
+from resnet_model.modeling_resnet import ResnetModel, ResnetModelForImageClassification
+```
+
+Then you have to tell the library you want to copy the code files of those objects when using the `save_pretrained`
+method and properly register them with a given Auto class (especially for models), just run:
+
+```py
+ResnetConfig.register_for_auto_class()
+ResnetModel.register_for_auto_class("AutoModel")
+ResnetModelForImageClassification.register_for_auto_class("AutoModelForImageClassification")
+```
+
+Note that there is no need to specify an auto class for the configuration (there is only one auto class for them,
+[`AutoConfig`]) but it's different for models. Your custom model could be suitable for many different tasks, so you
+have to specify which one of the auto classes is the correct one for your model.
+
+Next, let's create the config and models as we did before:
+
+```py
+resnet50d_config = ResnetConfig(block_type="bottleneck", stem_width=32, stem_type="deep", avg_down=True)
+resnet50d = ResnetModelForImageClassification(resnet50d_config)
+
+pretrained_model = timm.create_model("resnet50d", pretrained=True)
+resnet50d.model.load_state_dict(pretrained_model.state_dict())
+```
+
+Now to send the model to the Hub, make sure you are logged in. Either run in your terminal:
+
+```bash
+huggingface-cli login
+```
+
+or from a notebook:
+
+```py
+from huggingface_hub import notebook_login
+
+notebook_login()
+```
+
+You can then push to to your own namespace (or an organization you are a member of) like this:
+
+```py
+resnet50d.push_to_hub("custom-resnet50d")
+```
+
+On top of the modeling weights and the configuration in json format, this also copied the modeling and
+configuration `.py` files in the folder `custom-resnet50d` and uploaded the result to the Hub. You can check the result
+in this [model repo](https://huggingface.co/sgugger/custom-resnet50d).
+
+See the [sharing tutorial](model_sharing) for more information on the push to Hub method.
+
+## Using a model with custom code
+
+You can use any configuration, model or tokenizer with custom code files in its repository with the auto-classes and
+the `from_pretrained` method. All files and code uploaded to the Hub are scanned for malware (refer to the [Hub security](https://huggingface.co/docs/hub/security#malware-scanning) documentation for more information), but you should still 
+review the model code and author to avoid executing malicious code on your machine. Set `trust_remote_code=True` to use
+a model with custom code:
+
+```py
+from transformers import AutoModelForImageClassification
+
+model = AutoModelForImageClassification.from_pretrained("sgugger/custom-resnet50d", trust_remote_code=True)
+```
+
+It is also strongly encouraged to pass a commit hash as a `revision` to make sure the author of the models did not
+update the code with some malicious new lines (unless you fully trust the authors of the models).
+
+```py
+commit_hash = "ed94a7c6247d8aedce4647f00f20de6875b5b292"
+model = AutoModelForImageClassification.from_pretrained(
+    "sgugger/custom-resnet50d", trust_remote_code=True, revision=commit_hash
+)
+```
+
+Note that when browsing the commit history of the model repo on the Hub, there is a button to easily copy the commit
+hash of any commit.
+
+## Registering a model with custom code to the auto classes
+
+If you are writing a library that extends 🤗 Transformers, you may want to extend the auto classes to include your own
+model. This is different from pushing the code to the Hub in the sense that users will need to import your library to
+get the custom models (contrarily to automatically downloading the model code from the Hub).
+
+As long as your config has a `model_type` attribute that is different from existing model types, and that your model
+classes have the right `config_class` attributes, you can just add them to the auto classes likes this:
+
+```py
+from transformers import AutoConfig, AutoModel, AutoModelForImageClassification
+
+AutoConfig.register("resnet", ResnetConfig)
+AutoModel.register(ResnetConfig, ResnetModel)
+AutoModelForImageClassification.register(ResnetConfig, ResnetModelForImageClassification)
+```
+
+Note that the first argument used when registering your custom config to [`AutoConfig`] needs to match the `model_type`
+of your custom config, and the first argument used when registering your custom models to any auto model class needs
+to match the `config_class` of those models.

 # Debugging
 
+## Multi-GPU Network Issues Debug
+
+When training or inferencing with `DistributedDataParallel` and multiple GPU, if you run into issue of inter-communication between processes and/or nodes, you can use the following script to diagnose network issues.
+
+```bash
+wget https://raw.githubusercontent.com/huggingface/transformers/master/scripts/distributed/torch-distributed-gpu-test.py
+```
+
+For example to test how 2 GPUs interact do:
+
+```bash
+python -m torch.distributed.run --nproc_per_node 2 --nnodes 1 torch-distributed-gpu-test.py
+```
+If both processes can talk to each and allocate GPU memory each will print an OK status.
+
+For more GPUs or nodes adjust the arguments in the script.
+
+You will find a lot more details inside the diagnostics script and even a recipe to how you could run it in a SLURM environment.
+
+An additional level of debug is to add `NCCL_DEBUG=INFO` environment variable as follows:
+
+```bash
+NCCL_DEBUG=INFO python -m torch.distributed.run --nproc_per_node 2 --nnodes 1 torch-distributed-gpu-test.py
+```
+
+This will dump a lot of NCCL-related debug information, which you can then search online if you find that some problems are reported. Or if you're not sure how to interpret the output you can share the log file in an Issue.

+## Model inputs
+
+Every model is different yet bears similarities with the others. Therefore most models use the same inputs, which are
+detailed here alongside usage examples.
+
+<a id='input-ids'></a>
+
+### Input IDs
+
+The input ids are often the only required parameters to be passed to the model as input. *They are token indices,
+numerical representations of tokens building the sequences that will be used as input by the model*.
+
+<Youtube id="VFp38yj8h3A"/>
+
+Each tokenizer works differently but the underlying mechanism remains the same. Here's an example using the BERT
+tokenizer, which is a [WordPiece](https://arxiv.org/pdf/1609.08144.pdf) tokenizer:
+
+```python
+>>> from transformers import BertTokenizer
+
+>>> tokenizer = BertTokenizer.from_pretrained("bert-base-cased")
+
+>>> sequence = "A Titan RTX has 24GB of VRAM"
+```
+
+The tokenizer takes care of splitting the sequence into tokens available in the tokenizer vocabulary.
+
+```python
+>>> tokenized_sequence = tokenizer.tokenize(sequence)
+```
+
+The tokens are either words or subwords. Here for instance, "VRAM" wasn't in the model vocabulary, so it's been split
+in "V", "RA" and "M". To indicate those tokens are not separate words but parts of the same word, a double-hash prefix
+is added for "RA" and "M":
+
+```python
+>>> print(tokenized_sequence)
+['A', 'Titan', 'R', '##T', '##X', 'has', '24', '##GB', 'of', 'V', '##RA', '##M']
+```
+
+These tokens can then be converted into IDs which are understandable by the model. This can be done by directly feeding
+the sentence to the tokenizer, which leverages the Rust implementation of [🤗 Tokenizers](https://github.com/huggingface/tokenizers) for peak performance.
+
+```python
+>>> inputs = tokenizer(sequence)
+```
+
+The tokenizer returns a dictionary with all the arguments necessary for its corresponding model to work properly. The
+token indices are under the key "input_ids":
+
+```python
+>>> encoded_sequence = inputs["input_ids"]
+>>> print(encoded_sequence)
+[101, 138, 18696, 155, 1942, 3190, 1144, 1572, 13745, 1104, 159, 9664, 2107, 102]
+```
+
+Note that the tokenizer automatically adds "special tokens" (if the associated model relies on them) which are special
+IDs the model sometimes uses.
+
+If we decode the previous sequence of ids,
+
+```python
+>>> decoded_sequence = tokenizer.decode(encoded_sequence)
+```
+
+we will see
+
+```python
+>>> print(decoded_sequence)
+[CLS] A Titan RTX has 24GB of VRAM [SEP]
+```
+
+because this is the way a [`BertModel`] is going to expect its inputs.
+
+<a id='attention-mask'></a>
+
+### Attention mask
+
+The attention mask is an optional argument used when batching sequences together.
+
+<Youtube id="M6adb1j2jPI"/>
+
+This argument indicates to the model which tokens should be attended to, and which should not.
+
+For example, consider these two sequences:
+
+```python
+>>> from transformers import BertTokenizer
+
+>>> tokenizer = BertTokenizer.from_pretrained("bert-base-cased")
+
+>>> sequence_a = "This is a short sequence."
+>>> sequence_b = "This is a rather long sequence. It is at least longer than the sequence A."
+
+>>> encoded_sequence_a = tokenizer(sequence_a)["input_ids"]
+>>> encoded_sequence_b = tokenizer(sequence_b)["input_ids"]
+```
+
+The encoded versions have different lengths:
+
+```python
+>>> len(encoded_sequence_a), len(encoded_sequence_b)
+(8, 19)
+```
+
+Therefore, we can't put them together in the same tensor as-is. The first sequence needs to be padded up to the length
+of the second one, or the second one needs to be truncated down to the length of the first one.
+
+In the first case, the list of IDs will be extended by the padding indices. We can pass a list to the tokenizer and ask
+it to pad like this:
+
+```python
+>>> padded_sequences = tokenizer([sequence_a, sequence_b], padding=True)
+```
+
+We can see that 0s have been added on the right of the first sentence to make it the same length as the second one:
+
+```python
+>>> padded_sequences["input_ids"]
+[[101, 1188, 1110, 170, 1603, 4954, 119, 102, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [101, 1188, 1110, 170, 1897, 1263, 4954, 119, 1135, 1110, 1120, 1655, 2039, 1190, 1103, 4954, 138, 119, 102]]
+```
+
+This can then be converted into a tensor in PyTorch or TensorFlow. The attention mask is a binary tensor indicating the
+position of the padded indices so that the model does not attend to them. For the [`BertTokenizer`],
+`1` indicates a value that should be attended to, while `0` indicates a padded value. This attention mask is
+in the dictionary returned by the tokenizer under the key "attention_mask":
+
+```python
+>>> padded_sequences["attention_mask"]
+[[1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]]
+```
+
+<a id='token-type-ids'></a>
+
+### Token Type IDs
+
+Some models' purpose is to do classification on pairs of sentences or question answering.
+
+<Youtube id="0u3ioSwev3s"/>
+
+These require two different sequences to be joined in a single "input_ids" entry, which usually is performed with the
+help of special tokens, such as the classifier (`[CLS]`) and separator (`[SEP]`) tokens. For example, the BERT
+model builds its two sequence input as such:
+
+```python
+>>> # [CLS] SEQUENCE_A [SEP] SEQUENCE_B [SEP]
+```
+
+We can use our tokenizer to automatically generate such a sentence by passing the two sequences to `tokenizer` as two
+arguments (and not a list, like before) like this:
+
+```python
+>>> from transformers import BertTokenizer
+
+>>> tokenizer = BertTokenizer.from_pretrained("bert-base-cased")
+>>> sequence_a = "HuggingFace is based in NYC"
+>>> sequence_b = "Where is HuggingFace based?"
+
+>>> encoded_dict = tokenizer(sequence_a, sequence_b)
+>>> decoded = tokenizer.decode(encoded_dict["input_ids"])
+```
+
+which will return:
+
+```python
+>>> print(decoded)
+[CLS] HuggingFace is based in NYC [SEP] Where is HuggingFace based? [SEP]
+```
+
+This is enough for some models to understand where one sequence ends and where another begins. However, other models,
+such as BERT, also deploy token type IDs (also called segment IDs). They are represented as a binary mask identifying
+the two types of sequence in the model.
+
+The tokenizer returns this mask as the "token_type_ids" entry:
+
+```python
+>>> encoded_dict["token_type_ids"]
+[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1]
+```
+
+The first sequence, the "context" used for the question, has all its tokens represented by a `0`, whereas the
+second sequence, corresponding to the "question", has all its tokens represented by a `1`.
+
+Some models, like [`XLNetModel`] use an additional token represented by a `2`.
+
+<a id='position-ids'></a>
+
+### Position IDs
+
+Contrary to RNNs that have the position of each token embedded within them, transformers are unaware of the position of
+each token. Therefore, the position IDs (`position_ids`) are used by the model to identify each token's position in
+the list of tokens.
+
+They are an optional parameter. If no `position_ids` are passed to the model, the IDs are automatically created as
+absolute positional embeddings.
+
+Absolute positional embeddings are selected in the range `[0, config.max_position_embeddings - 1]`. Some models use
+other types of positional embeddings, such as sinusoidal position embeddings or relative position embeddings.
+
+<a id='labels'></a>
+
+### Labels
+
+The labels are an optional argument which can be passed in order for the model to compute the loss itself. These labels
+should be the expected prediction of the model: it will use the standard loss in order to compute the loss between its
+predictions and the expected value (the label).
+
+These labels are different according to the model head, for example:
+
+- For sequence classification models (e.g., [`BertForSequenceClassification`]), the model expects a
+  tensor of dimension `(batch_size)` with each value of the batch corresponding to the expected label of the
+  entire sequence.
+- For token classification models (e.g., [`BertForTokenClassification`]), the model expects a tensor
+  of dimension `(batch_size, seq_length)` with each value corresponding to the expected label of each individual
+  token.
+- For masked language modeling (e.g., [`BertForMaskedLM`]), the model expects a tensor of dimension
+  `(batch_size, seq_length)` with each value corresponding to the expected label of each individual token: the
+  labels being the token ID for the masked token, and values to be ignored for the rest (usually -100).
+- For sequence to sequence tasks,(e.g., [`BartForConditionalGeneration`],
+  [`MBartForConditionalGeneration`]), the model expects a tensor of dimension `(batch_size, tgt_seq_length)` with each value corresponding to the target sequences associated with each input sequence. During
+  training, both *BART* and *T5* will make the appropriate *decoder_input_ids* and decoder attention masks internally.
+  They usually do not need to be supplied. This does not apply to models leveraging the Encoder-Decoder framework. See
+  the documentation of each model for more information on each specific model's labels.
+
+The base models (e.g., [`BertModel`]) do not accept labels, as these are the base transformer
+models, simply outputting features.
+
+<a id='decoder-input-ids'></a>
+
+### Decoder input IDs
+
+This input is specific to encoder-decoder models, and contains the input IDs that will be fed to the decoder. These
+inputs should be used for sequence to sequence tasks, such as translation or summarization, and are usually built in a
+way specific to each model.
+
+Most encoder-decoder models (BART, T5) create their `decoder_input_ids` on their own from the `labels`. In
+such models, passing the `labels` is the preferred way to handle training.
+
+Please check each model's docs to see how they handle these input IDs for sequence to sequence training.
+
+<a id='feed-forward-chunking'></a>
+
+### Feed Forward Chunking
+
+In each residual attention block in transformers the self-attention layer is usually followed by 2 feed forward layers.
+The intermediate embedding size of the feed forward layers is often bigger than the hidden size of the model (e.g., for
+`bert-base-uncased`).
+
+For an input of size `[batch_size, sequence_length]`, the memory required to store the intermediate feed forward
+embeddings `[batch_size, sequence_length, config.intermediate_size]` can account for a large fraction of the memory
+use. The authors of [Reformer: The Efficient Transformer](https://arxiv.org/abs/2001.04451) noticed that since the
+computation is independent of the `sequence_length` dimension, it is mathematically equivalent to compute the output
+embeddings of both feed forward layers `[batch_size, config.hidden_size]_0, ..., [batch_size, config.hidden_size]_n`
+individually and concat them afterward to `[batch_size, sequence_length, config.hidden_size]` with `n = sequence_length`, which trades increased computation time against reduced memory use, but yields a mathematically
+**equivalent** result.
+
+For models employing the function [`apply_chunking_to_forward`], the `chunk_size` defines the
+number of output embeddings that are computed in parallel and thus defines the trade-off between memory and time
+complexity. If `chunk_size` is set to 0, no feed forward chunking is done.

-This argument indicates to the model which tokens should be attended to, and which should not.

-    [[101, 1188, 1110, 170, 1603, 4954, 119, 102, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [101, 1188, 1110, 170, 1897, 1263, 4954, 119, 1135, 1110, 1120, 1655, 2039, 1190, 1103, 4954, 138, 119, 102]]
-
-This can then be converted into a tensor in PyTorch or TensorFlow. The attention mask is a binary tensor indicating the
-position of the padded indices so that the model does not attend to them. For the :class:`~transformers.BertTokenizer`,
-:obj:`1` indicates a value that should be attended to, while :obj:`0` indicates a padded value. This attention mask is
-in the dictionary returned by the tokenizer under the key "attention_mask":
-
-.. code-block::
-
-    >>> padded_sequences["attention_mask"]
-    [[1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]]
-
-.. _token-type-ids:
-
-Token Type IDs
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Some models' purpose is to do classification on pairs of sentences or question answering.
-
-.. raw:: html
-
-   <iframe width="560" height="315" src="https://www.youtube.com/embed/0u3ioSwev3s" title="YouTube video player"
-   frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope;
-   picture-in-picture" allowfullscreen></iframe>
-
-These require two different sequences to be joined in a single "input_ids" entry, which usually is performed with the
-help of special tokens, such as the classifier (``[CLS]``) and separator (``[SEP]``) tokens. For example, the BERT
-model builds its two sequence input as such:
-
-.. code-block::
-
-    >>> # [CLS] SEQUENCE_A [SEP] SEQUENCE_B [SEP]
-
-We can use our tokenizer to automatically generate such a sentence by passing the two sequences to ``tokenizer`` as two
-arguments (and not a list, like before) like this:
-
-.. code-block::
-
-    >>> from transformers import BertTokenizer
-    >>> tokenizer = BertTokenizer.from_pretrained("bert-base-cased")
-    >>> sequence_a = "HuggingFace is based in NYC"
-    >>> sequence_b = "Where is HuggingFace based?"
-
-    >>> encoded_dict = tokenizer(sequence_a, sequence_b)
-    >>> decoded = tokenizer.decode(encoded_dict["input_ids"])
-
-which will return:
-
-.. code-block::
-
-    >>> print(decoded)
-    [CLS] HuggingFace is based in NYC [SEP] Where is HuggingFace based? [SEP]
-
-This is enough for some models to understand where one sequence ends and where another begins. However, other models,
-such as BERT, also deploy token type IDs (also called segment IDs). They are represented as a binary mask identifying
-the two types of sequence in the model.
-
-The tokenizer returns this mask as the "token_type_ids" entry:
-
-.. code-block::
-
-    >>> encoded_dict['token_type_ids']
-    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1]
-
-The first sequence, the "context" used for the question, has all its tokens represented by a :obj:`0`, whereas the
-second sequence, corresponding to the "question", has all its tokens represented by a :obj:`1`.
-
-Some models, like :class:`~transformers.XLNetModel` use an additional token represented by a :obj:`2`.
-
-.. _position-ids:
-
-Position IDs
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Contrary to RNNs that have the position of each token embedded within them, transformers are unaware of the position of
-each token. Therefore, the position IDs (``position_ids``) are used by the model to identify each token's position in
-the list of tokens.
-
-They are an optional parameter. If no ``position_ids`` are passed to the model, the IDs are automatically created as
-absolute positional embeddings.
-
-Absolute positional embeddings are selected in the range ``[0, config.max_position_embeddings - 1]``. Some models use
-other types of positional embeddings, such as sinusoidal position embeddings or relative position embeddings.
-
-.. _labels:
-
-Labels
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The labels are an optional argument which can be passed in order for the model to compute the loss itself. These labels
-should be the expected prediction of the model: it will use the standard loss in order to compute the loss between its
-predictions and the expected value (the label).
-
-These labels are different according to the model head, for example:
-
-- For sequence classification models (e.g., :class:`~transformers.BertForSequenceClassification`), the model expects a
-  tensor of dimension :obj:`(batch_size)` with each value of the batch corresponding to the expected label of the
-  entire sequence.
-- For token classification models (e.g., :class:`~transformers.BertForTokenClassification`), the model expects a tensor
-  of dimension :obj:`(batch_size, seq_length)` with each value corresponding to the expected label of each individual
-  token.
-- For masked language modeling (e.g., :class:`~transformers.BertForMaskedLM`), the model expects a tensor of dimension
-  :obj:`(batch_size, seq_length)` with each value corresponding to the expected label of each individual token: the
-  labels being the token ID for the masked token, and values to be ignored for the rest (usually -100).
-- For sequence to sequence tasks,(e.g., :class:`~transformers.BartForConditionalGeneration`,
-  :class:`~transformers.MBartForConditionalGeneration`), the model expects a tensor of dimension :obj:`(batch_size,
-  tgt_seq_length)` with each value corresponding to the target sequences associated with each input sequence. During
-  training, both `BART` and `T5` will make the appropriate `decoder_input_ids` and decoder attention masks internally.
-  They usually do not need to be supplied. This does not apply to models leveraging the Encoder-Decoder framework. See
-  the documentation of each model for more information on each specific model's labels.
-
-The base models (e.g., :class:`~transformers.BertModel`) do not accept labels, as these are the base transformer
-models, simply outputting features.
-
-.. _decoder-input-ids:
-
-Decoder input IDs
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This input is specific to encoder-decoder models, and contains the input IDs that will be fed to the decoder. These
-inputs should be used for sequence to sequence tasks, such as translation or summarization, and are usually built in a
-way specific to each model.
-
-Most encoder-decoder models (BART, T5) create their :obj:`decoder_input_ids` on their own from the :obj:`labels`. In
-such models, passing the :obj:`labels` is the preferred way to handle training.
-
-Please check each model's docs to see how they handle these input IDs for sequence to sequence training.
-
-.. _feed-forward-chunking:
-
-Feed Forward Chunking
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In each residual attention block in transformers the self-attention layer is usually followed by 2 feed forward layers.
-The intermediate embedding size of the feed forward layers is often bigger than the hidden size of the model (e.g., for
-``bert-base-uncased``).
-
-For an input of size ``[batch_size, sequence_length]``, the memory required to store the intermediate feed forward
-embeddings ``[batch_size, sequence_length, config.intermediate_size]`` can account for a large fraction of the memory
-use. The authors of `Reformer: The Efficient Transformer <https://arxiv.org/abs/2001.04451>`_ noticed that since the
-computation is independent of the ``sequence_length`` dimension, it is mathematically equivalent to compute the output
-embeddings of both feed forward layers ``[batch_size, config.hidden_size]_0, ..., [batch_size, config.hidden_size]_n``
-individually and concat them afterward to ``[batch_size, sequence_length, config.hidden_size]`` with ``n =
-sequence_length``, which trades increased computation time against reduced memory use, but yields a mathematically
-**equivalent** result.
-
-For models employing the function :func:`~.transformers.apply_chunking_to_forward`, the ``chunk_size`` defines the
-number of output embeddings that are computed in parallel and thus defines the trade-off between memory and time
-complexity. If ``chunk_size`` is set to 0, no feed forward chunking is done.

-# Installation
-
-🤗 Transformers is tested on Python 3.6+, and PyTorch 1.1.0+ or TensorFlow 2.0+.
-
-You should install 🤗 Transformers in a [virtual environment](https://docs.python.org/3/library/venv.html). If you're
-unfamiliar with Python virtual environments, check out the [user guide](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/). Create a virtual environment with the version of Python you're going
-to use and activate it.
-
-Now, if you want to use 🤗 Transformers, you can install it with pip. If you'd like to play with the examples, you
-must install it from source.
-
-## Installation with pip
-
-First you need to install one of, or both, TensorFlow 2.0 and PyTorch.
-Please refer to [TensorFlow installation page](https://www.tensorflow.org/install/pip#tensorflow-2.0-rc-is-available),
-[PyTorch installation page](https://pytorch.org/get-started/locally/#start-locally) and/or
-[Flax installation page](https://github.com/google/flax#quick-install)
-regarding the specific install command for your platform.
-
-When TensorFlow 2.0 and/or PyTorch has been installed, 🤗 Transformers can be installed using pip as follows:
-
-```bash
-pip install transformers
-```
-
-Alternatively, for CPU-support only, you can install 🤗 Transformers and PyTorch in one line with:
-
-```bash
-pip install transformers[torch]
-```
-
-or 🤗 Transformers and TensorFlow 2.0 in one line with:
-
-```bash
-pip install transformers[tf-cpu]
-```
-
-or 🤗 Transformers and Flax in one line with:
-
-```bash
-pip install transformers[flax]
-```
-
-To check 🤗 Transformers is properly installed, run the following command:
-
-```bash
-python -c "from transformers import pipeline; print(pipeline('sentiment-analysis')('we love you'))"
-```
-
-It should download a pretrained model then print something like
-
-```bash
-[{'label': 'POSITIVE', 'score': 0.9998704791069031}]
-```
-
-(Note that TensorFlow will print additional stuff before that last statement.)
-
-## Installing from source
-
-Here is how to quickly install `transformers` from source:
-
-```bash
-pip install git+https://github.com/huggingface/transformers
-```
-
-Note that this will install not the latest released version, but the bleeding edge `master` version, which you may want to use in case a bug has been fixed since the last official release and a new release hasn't been yet rolled out.
-
-While we strive to keep `master` operational at all times, if you notice some issues, they usually get fixed within a few hours or a day and you're more than welcome to help us detect any problems by opening an [Issue](https://github.com/huggingface/transformers/issues) and this way, things will get fixed even sooner.
-
-Again, you can run:
-
-```bash
-python -c "from transformers import pipeline; print(pipeline('sentiment-analysis')('I hate you'))"
-```
-
-to check 🤗 Transformers is properly installed.
-
-## Editable install
-
-If you want to constantly use the bleeding edge `master` version of the source code, or if you want to contribute to the library and need to test the changes in the code you're making, you will need an editable install. This is done by cloning the repository and installing with the following commands:
-
-``` bash
-git clone https://github.com/huggingface/transformers.git
-cd transformers
-pip install -e .
-```
-
-This command performs a magical link between the folder you cloned the repository to and your python library paths, and it'll look inside this folder in addition to the normal library-wide paths. So if normally your python packages get installed into:
-```
-~/anaconda3/envs/main/lib/python3.7/site-packages/
-```
-now this editable install will reside where you clone the folder to, e.g. `~/transformers/` and python will search it too.
-
-Do note that you have to keep that `transformers` folder around and not delete it to continue using the  `transformers` library.
-
-Now, let's get to the real benefit of this installation approach. Say, you saw some new feature has been just committed into `master`. If you have already performed all the steps above, to update your transformers to include all the latest commits, all you need to do is to `cd` into that cloned repository folder and update the clone to the latest version:
-
-```
-cd ~/transformers/
-git pull
-```
-
-There is nothing else to do. Your python environment will find the bleeding edge version of `transformers` on the next run.
-
-
-## With conda
-
-Since Transformers version v4.0.0, we now have a conda channel: `huggingface`.
-
-🤗 Transformers can be installed using conda as follows:
-
-```
-conda install -c huggingface transformers
-```
-
-Follow the installation pages of TensorFlow, PyTorch or Flax to see how to install them with conda.
-
-## Caching models
-
-This library provides pretrained models that will be downloaded and cached locally. Unless you specify a location with
-`cache_dir=...` when you use methods like `from_pretrained`, these models will automatically be downloaded in the
-folder given by the shell environment variable ``TRANSFORMERS_CACHE``. The default value for it will be the Hugging
-Face cache home followed by ``/transformers/``. This is (by order of priority):
-
-  * shell environment variable ``HF_HOME``
-  * shell environment variable ``XDG_CACHE_HOME`` + ``/huggingface/``
-  * default: ``~/.cache/huggingface/``
-
-So if you don't have any specific environment variable set, the cache directory will be at
-``~/.cache/huggingface/transformers/``.
-
-**Note:** If you have set a shell environment variable for one of the predecessors of this library
-(``PYTORCH_TRANSFORMERS_CACHE`` or ``PYTORCH_PRETRAINED_BERT_CACHE``), those will be used if there is no shell
-environment variable for ``TRANSFORMERS_CACHE``.
-
-### Offline mode
-
-It's possible to run 🤗 Transformers in a firewalled or a no-network environment.
-
-Setting environment variable `TRANSFORMERS_OFFLINE=1` will tell 🤗 Transformers to use local files only and will not try to look things up.
-
-Most likely you may want to couple this with `HF_DATASETS_OFFLINE=1` that performs the same for 🤗 Datasets if you're using the latter.
-
-Here is an example of how this can be used on a filesystem that is shared between a normally networked and a firewalled to the external world instances.
-
-On the instance with the normal network run your program which will download and cache models (and optionally datasets if you use 🤗 Datasets). For example:
-
-```
-python examples/pytorch/translation/run_translation.py --model_name_or_path t5-small --dataset_name wmt16 --dataset_config ro-en ...
-```
-
-and then with the same filesystem you can now run the same program on a firewalled instance:
-```
-HF_DATASETS_OFFLINE=1 TRANSFORMERS_OFFLINE=1 \
-python examples/pytorch/translation/run_translation.py --model_name_or_path t5-small --dataset_name wmt16 --dataset_config ro-en ...
-```
-and it should succeed without any hanging waiting to timeout.
-
-#### Fetching models and tokenizers to use offline
-
-When running a script the first time like mentioned above, the downloaded files will be cached for future reuse. 
-However, it is also possible to download files and point to their local path instead.
-
-Downloading files can be done through the Web Interface by clicking on the "Download" button, but it can also be handled
-programmatically using the `huggingface_hub` library that is a dependency to `transformers`:
-
-- Using `snapshot_download` to download an entire repository
-- Using `hf_hub_download` to download a specific file
-
-See the reference for these methods in the huggingface_hub
-[documentation](https://github.com/huggingface/huggingface_hub/tree/main/src/huggingface_hub).
-
-## Do you want to run a Transformer model on a mobile device?
-
-You should check out our [swift-coreml-transformers](https://github.com/huggingface/swift-coreml-transformers) repo.
-
-It contains a set of tools to convert PyTorch or TensorFlow 2.0 trained Transformer models (currently contains `GPT-2`,
-`DistilGPT-2`, `BERT`, and `DistilBERT`) to CoreML models that run on iOS devices.
-
-At some point in the future, you'll be able to seamlessly move from pretraining or fine-tuning models in PyTorch or
-TensorFlow 2.0 to productizing them in CoreML, or prototype a model or an app in CoreML then research its
-hyperparameters or architecture from PyTorch or TensorFlow 2.0. Super exciting!

+
+# Installation
+
+Install 🤗 Transformers for whichever deep learning library you're working with, setup your cache, and optionally configure 🤗 Transformers to run offline.
+
+🤗 Transformers is tested on Python 3.6+, PyTorch 1.1.0+, TensorFlow 2.0+, and Flax. Follow the installation instructions below for the deep learning library you are using:
+
+* [PyTorch](https://pytorch.org/get-started/locally/) installation instructions.
+* [TensorFlow 2.0](https://www.tensorflow.org/install/pip) installation instructions.
+* [Flax](https://flax.readthedocs.io/en/latest/) installation instructions.
+
+## Install with pip
+
+You should install 🤗 Transformers in a [virtual environment](https://docs.python.org/3/library/venv.html). If you're unfamiliar with Python virtual environments, take a look at this [guide](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/). A virtual environment makes it easier to manage different projects, and avoid compatibility issues between dependencies.
+
+Start by creating a virtual environment in your project directory:
+
+```bash
+python -m venv .env
+```
+
+Activate the virtual environment:
+
+```bash
+source .env/bin/activate
+```
+
+Now you're ready to install 🤗 Transformers with the following command:
+
+```bash
+pip install transformers
+```
+
+For CPU-support only, you can conveniently install 🤗 Transformers and a deep learning library in one line. For example, install 🤗 Transformers and PyTorch with:
+
+```bash
+pip install transformers[torch]
+```
+
+🤗 Transformers and TensorFlow 2.0:
+
+```bash
+pip install transformers[tf-cpu]
+```
+
+🤗 Transformers and Flax:
+
+```bash
+pip install transformers[flax]
+```
+
+Finally, check if 🤗 Transformers has been properly installed by running the following command. It will download a pretrained model:
+
+```bash
+python -c "from transformers import pipeline; print(pipeline('sentiment-analysis')('we love you'))"
+```
+
+Then print out the label and score:
+
+```bash
+[{'label': 'POSITIVE', 'score': 0.9998704791069031}]
+```
+
+## Install from source
+
+Install 🤗 Transformers from source with the following command:
+
+```bash
+pip install git+https://github.com/huggingface/transformers
+```
+
+This command installs the bleeding edge `master` version rather than the latest `stable` version. The `master` version is useful for staying up-to-date with the latest developments. For instance, if a bug has been fixed since the last official release but a new release hasn't been rolled out yet. However, this means the `master` version may not always be stable. We strive to keep the `master` version operational, and most issues are usually resolved within a few hours or a day. If you run into a problem, please open an [Issue](https://github.com/huggingface/transformers/issues) so we can fix it even sooner!
+
+Check if 🤗 Transformers has been properly installed by running the following command:
+
+```bash
+python -c "from transformers import pipeline; print(pipeline('sentiment-analysis')('I love you'))"
+```
+
+## Editable install
+
+You will need an editable install if you'd like to:
+
+* Use the `master` version of the source code.
+* Contribute to 🤗 Transformers and need to test changes in the code.
+
+Clone the repository and install 🤗 Transformers with the following commands:
+
+```bash
+git clone https://github.com/huggingface/transformers.git
+cd transformers
+pip install -e .
+```
+
+These commands will link the folder you cloned the repository to and your Python library paths. Python will now look inside the folder you cloned to in addition to the normal library paths. For example, if your Python packages are typically installed in `~/anaconda3/envs/main/lib/python3.7/site-packages/`, Python will also search the folder you cloned to: `~/transformers/`.
+
+<Tip warning={true}>
+
+You must keep the `transformers` folder if you want to keep using the library.
+
+</Tip>
+
+Now you can easily update your clone to the latest version of 🤗 Transformers with the following command:
+
+```bash
+cd ~/transformers/
+git pull
+```
+
+Your Python environment will find the `master` version of 🤗 Transformers on the next run.
+
+## Install with conda
+
+Install from the conda channel `huggingface`:
+
+```bash
+conda install -c huggingface transformers
+```
+
+## Cache setup
+
+Pretrained models are downloaded and locally cached at: `~/.cache/huggingface/transformers/`. This is the default directory given by the shell environment variable `TRANSFORMERS_CACHE`. On Windows, the default directory is given by `C:\Users\username\.cache\huggingface\transformers`. You can change the shell environment variables shown below - in order of priority - to specify a different cache directory:
+
+1. Shell environment variable (default): `TRANSFORMERS_CACHE`.
+2. Shell environment variable: `HF_HOME` + `transformers/`.
+3. Shell environment variable: `XDG_CACHE_HOME` + `/huggingface/transformers`.
+
+<Tip>
+
+🤗 Transformers will use the shell environment variables `PYTORCH_TRANSFORMERS_CACHE` or `PYTORCH_PRETRAINED_BERT_CACHE` if you are coming from an earlier iteration of this library and have set those environment variables, unless you specify the shell environment variable `TRANSFORMERS_CACHE`.
+
+</Tip>
+
+## Offline mode
+
+🤗 Transformers is able to run in a firewalled or offline environment by only using local files. Set the environment variable `TRANSFORMERS_OFFLINE=1` to enable this behavior.
+
+<Tip>
+
+Add [🤗 Datasets](https://huggingface.co/docs/datasets/) to your offline training workflow by setting the environment variable `HF_DATASETS_OFFLINE=1`.
+
+</Tip>
+
+For example, you would typically run a program on a normal network firewalled to external instances with the following command:
+
+```bash
+python examples/pytorch/translation/run_translation.py --model_name_or_path t5-small --dataset_name wmt16 --dataset_config ro-en ...
+```
+
+Run this same program in an offline instance with:
+
+```bash
+HF_DATASETS_OFFLINE=1 TRANSFORMERS_OFFLINE=1 \
+python examples/pytorch/translation/run_translation.py --model_name_or_path t5-small --dataset_name wmt16 --dataset_config ro-en ...
+```
+
+The script should now run without hanging or waiting to timeout because it knows it should only look for local files.
+
+### Fetch models and tokenizers to use offline
+
+Another option for using 🤗 Transformers offline is to download the files ahead of time, and then point to their local path when you need to use them offline. There are three ways to do this:
+
+* Download a file through the user interface on the [Model Hub](https://huggingface.co/models) by clicking on the ↓ icon.
+
+    ![download-icon](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/download-icon.png)
+
+* Use the [`PreTrainedModel.from_pretrained`] and [`PreTrainedModel.save_pretrained`] workflow:
+
+    1. Download your files ahead of time with [`PreTrainedModel.from_pretrained`]:
+
+    ```py
+    >>> from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
+
+    >>> tokenizer = AutoTokenizer.from_pretrained("bigscience/T0_3B")
+    >>> model = AutoModelForSeq2SeqLM.from_pretrained("bigscience/T0_3B")
+    ```
+
+    2. Save your files to a specified directory with [`PreTrainedModel.save_pretrained`]:
+
+    ```py
+    >>> tokenizer.save_pretrained("./your/path/bigscience_t0")
+    >>> model.save_pretrained("./your/path/bigscience_t0")
+    ```
+
+    3. Now when you're offline, reload your files with [`PreTrainedModel.from_pretrained`] from the specified directory:
+
+    ```py
+    >>> tokenizer = AutoTokenizer.from_pretrained("./your/path/bigscience_t0")
+    >>> model = AutoModel.from_pretrained("./your/path/bigscience_t0")
+    ```
+
+* Programmatically download files with the [huggingface_hub](https://github.com/huggingface/huggingface_hub/tree/main/src/huggingface_hub) library:
+
+    1. Install the `huggingface_hub` library in your virtual environment:
+
+    ```bash
+    python -m pip install huggingface_hub
+    ```
+
+    2. Use the [`hf_hub_download`](https://huggingface.co/docs/hub/adding-a-library#download-files-from-the-hub) function to download a file to a specific path. For example, the following command downloads the `config.json` file from the [T0](https://huggingface.co/bigscience/T0_3B) model to your desired path:
+
+    ```py
+    >>> from huggingface_hub import hf_hub_download
+
+    >>> hf_hub_download(repo_id="bigscience/T0_3B", filename="config.json", cache_dir="./your/path/bigscience_t0")
+    ```
+
+Once your file is downloaded and locally cached, specify it's local path to load and use it:
+
+```py
+>>> from transformers import AutoConfig
+
+>>> config = AutoConfig.from_pretrained("./your/path/bigscience_t0/config.json")
+```
+
+<Tip>
+
+See the [How to download files from the Hub](https://huggingface.co/docs/hub/how-to-downstream) section for more details on downloading files stored on the Hub.
+
+</Tip>

+# Utilities for Generation
+
+This page lists all the utility functions used by [`~generation_utils.GenerationMixin.generate`],
+[`~generation_utils.GenerationMixin.greedy_search`],
+[`~generation_utils.GenerationMixin.sample`],
+[`~generation_utils.GenerationMixin.beam_search`],
+[`~generation_utils.GenerationMixin.beam_sample`],
+[`~generation_utils.GenerationMixin.group_beam_search`], and
+[`~generation_utils.GenerationMixin.constrained_beam_search`].
+
+Most of those are only useful if you are studying the code of the generate methods in the library.
+
+## Generate Outputs
+
+The output of [`~generation_utils.GenerationMixin.generate`] is an instance of a subclass of
+[`~file_utils.ModelOutput`]. This output is a data structure containing all the information returned
+by [`~generation_utils.GenerationMixin.generate`], but that can also be used as tuple or dictionary.
+
+Here's an example:
+
+```python
+from transformers import GPT2Tokenizer, GPT2LMHeadModel
+
+tokenizer = GPT2Tokenizer.from_pretrained("gpt2")
+model = GPT2LMHeadModel.from_pretrained("gpt2")
+
+inputs = tokenizer("Hello, my dog is cute and ", return_tensors="pt")
+generation_output = model.generate(**inputs, return_dict_in_generate=True, output_scores=True)
+```
+
+The `generation_output` object is a [`~generation_utils.GreedySearchDecoderOnlyOutput`], as we can
+see in the documentation of that class below, it means it has the following attributes:
+
+- `sequences`: the generated sequences of tokens
+- `scores` (optional): the prediction scores of the language modelling head, for each generation step
+- `hidden_states` (optional): the hidden states of the model, for each generation step
+- `attentions` (optional): the attention weights of the model, for each generation step
+
+Here we have the `scores` since we passed along `output_scores=True`, but we don't have `hidden_states` and
+`attentions` because we didn't pass `output_hidden_states=True` or `output_attentions=True`.
+
+You can access each attribute as you would usually do, and if that attribute has not been returned by the model, you
+will get `None`. Here for instance `generation_output.scores` are all the generated prediction scores of the
+language modeling head, and `generation_output.attentions` is `None`.
+
+When using our `generation_output` object as a tuple, it only keeps the attributes that don't have `None` values.
+Here, for instance, it has two elements, `loss` then `logits`, so
+
+```python
+generation_output[:2]
+```
+
+will return the tuple `(generation_output.sequences, generation_output.scores)` for instance.
+
+When using our `generation_output` object as a dictionary, it only keeps the attributes that don't have `None`
+values. Here, for instance, it has two keys that are `sequences` and `scores`.
+
+We document here all output types.

+# Callbacks
+
+Callbacks are objects that can customize the behavior of the training loop in the PyTorch
+[`Trainer`] (this feature is not yet implemented in TensorFlow) that can inspect the training loop
+state (for progress reporting, logging on TensorBoard or other ML platforms...) and take decisions (like early
+stopping).
+
+Callbacks are "read only" pieces of code, apart from the [`TrainerControl`] object they return, they
+cannot change anything in the training loop. For customizations that require changes in the training loop, you should
+subclass [`Trainer`] and override the methods you need (see [trainer](trainer) for examples).
+
+By default a [`Trainer`] will use the following callbacks:
+
+- [`DefaultFlowCallback`] which handles the default behavior for logging, saving and evaluation.
+- [`PrinterCallback`] or [`ProgressCallback`] to display progress and print the
+  logs (the first one is used if you deactivate tqdm through the [`TrainingArguments`], otherwise
+  it's the second one).
+- [`~integrations.TensorBoardCallback`] if tensorboard is accessible (either through PyTorch >= 1.4
+  or tensorboardX).
+- [`~integrations.WandbCallback`] if [wandb](https://www.wandb.com/) is installed.
+- [`~integrations.CometCallback`] if [comet_ml](https://www.comet.ml/site/) is installed.
+- [`~integrations.MLflowCallback`] if [mlflow](https://www.mlflow.org/) is installed.
+- [`~integrations.AzureMLCallback`] if [azureml-sdk](https://pypi.org/project/azureml-sdk/) is
+  installed.
+- [`~integrations.CodeCarbonCallback`] if [codecarbon](https://pypi.org/project/codecarbon/) is
+  installed.
+
+The main class that implements callbacks is [`TrainerCallback`]. It gets the
+[`TrainingArguments`] used to instantiate the [`Trainer`], can access that
+Trainer's internal state via [`TrainerState`], and can take some actions on the training loop via
+[`TrainerControl`].
+
+
+## Available Callbacks
+
+Here is the list of the available [`TrainerCallback`] in the library:
+
+[[autodoc]] integrations.CometCallback
+    - setup
+
+[[autodoc]] DefaultFlowCallback
+
+[[autodoc]] PrinterCallback
+
+[[autodoc]] ProgressCallback
+
+[[autodoc]] EarlyStoppingCallback

+    - setup
+
+[[autodoc]] integrations.MLflowCallback
+    - setup
+
+[[autodoc]] integrations.AzureMLCallback
+
+[[autodoc]] integrations.CodeCarbonCallback
+
+## TrainerCallback
+
+[[autodoc]] TrainerCallback
+
+Here is an example of how to register a custom callback with the PyTorch [`Trainer`]:
+
+```python
+class MyCallback(TrainerCallback):
+    "A callback that prints a message at the beginning of training"
+
+    def on_train_begin(self, args, state, control, **kwargs):
+        print("Starting training")
+
+
+trainer = Trainer(
+    model,
+    args,
+    train_dataset=train_dataset,
+    eval_dataset=eval_dataset,
+    callbacks=[MyCallback],  # We can either pass the callback class this way or an instance of it (MyCallback())
+)
+```
+
+Another way to register a callback is to call `trainer.add_callback()` as follows:
+
+```python
+trainer = Trainer(...)
+trainer.add_callback(MyCallback)
+# Alternatively, we can pass an instance of the callback class
+trainer.add_callback(MyCallback())
+```

+Data collators are objects that will form a batch by using a list of dataset elements as input. These elements are of
+the same type as the elements of `train_dataset` or `eval_dataset`.
+
+To be able to build batches, data collators may apply some processing (like padding). Some of them (like
+[`DataCollatorForLanguageModeling`]) also apply some random data augmentation (like random masking)
+on the formed batch.

 Additionally DeepSpeed is currently developing a related product called Deepspeed-Inference which has no relationship
 to the ZeRO technology, but instead uses tensor parallelism to scale models that can't fit onto a single GPU. This is a
 work in progress and we will provide the integration once that product is complete.
 
 
+### Memory Requirements
+
+Since Deepspeed ZeRO can offload memory to CPU (and NVMe) the framework provides utils that allow one to tell how much CPU and GPU memory will be needed depending on the number of GPUs being used.
+
+Let's estimate how much memory is needed to finetune "bigscience/T0_3B" on a single GPU:
+
+```bash
+$ python -c 'from transformers import AutoModel; \
+from deepspeed.runtime.zero.stage3 import estimate_zero3_model_states_mem_needs_all_live; \
+model = AutoModel.from_pretrained("bigscience/T0_3B"); \
+estimate_zero3_model_states_mem_needs_all_live(model, num_gpus_per_node=1, num_nodes=1)'
+[...]
+Estimated memory needed for params, optim states and gradients for a:
+HW: Setup with 1 node, 1 GPU per node.
+SW: Model with 2783M total params, 65M largest layer params.
+  per CPU  |  per GPU |   Options
+   70.00GB |   0.25GB | offload_param=cpu , offload_optimizer=cpu , zero_init=1
+   70.00GB |   0.25GB | offload_param=cpu , offload_optimizer=cpu , zero_init=0
+   62.23GB |   5.43GB | offload_param=none, offload_optimizer=cpu , zero_init=1
+   62.23GB |   5.43GB | offload_param=none, offload_optimizer=cpu , zero_init=0
+    0.37GB |  46.91GB | offload_param=none, offload_optimizer=none, zero_init=1
+   15.56GB |  46.91GB | offload_param=none, offload_optimizer=none, zero_init=0
+```
+
+So you can fit it on a single 80GB GPU and no CPU offload, or a tiny 8GB GPU but then need ~60GB of CPU memory. (Remember this is just the memory for params, optimizer states and gradients - you will need a bit more memory for cuda kernels, activations and temps.)
+
+Then it's a tradeoff of cost vs speed. It'll be cheaper to buy/rent a smaller GPU (or less GPUs since you can use multiple GPUs with Deepspeed ZeRO. But then it'll be slower, so even if you don't care about how fast something will be done, the slowdown has a direct impact on the duration of using the GPU and thus bigger cost. So experiment and compare which works the best.
+
+If you have enough GPU memory make sure to disable the CPU/NVMe offload as it'll make everything faster.
+
+For example, let's repeat the same for 2 GPUs:
+
+```bash
+$ python -c 'from transformers import AutoModel; \
+from deepspeed.runtime.zero.stage3 import estimate_zero3_model_states_mem_needs_all_live; \
+model = AutoModel.from_pretrained("bigscience/T0_3B"); \
+estimate_zero3_model_states_mem_needs_all_live(model, num_gpus_per_node=2, num_nodes=1)'
+[...]
+Estimated memory needed for params, optim states and gradients for a:
+HW: Setup with 1 node, 2 GPUs per node.
+SW: Model with 2783M total params, 65M largest layer params.
+  per CPU  |  per GPU |   Options
+   70.00GB |   0.25GB | offload_param=cpu , offload_optimizer=cpu , zero_init=1
+   70.00GB |   0.25GB | offload_param=cpu , offload_optimizer=cpu , zero_init=0
+   62.23GB |   2.84GB | offload_param=none, offload_optimizer=cpu , zero_init=1
+   62.23GB |   2.84GB | offload_param=none, offload_optimizer=cpu , zero_init=0
+    0.74GB |  23.58GB | offload_param=none, offload_optimizer=none, zero_init=1
+   31.11GB |  23.58GB | offload_param=none, offload_optimizer=none, zero_init=0
+
+```
+
+So here you'd want 2x 32GB GPUs or higher without offloading to CPU.

 ### Troubleshooting
 
-- `deepspeed` process gets killed at startup without a traceback
+#### the `deepspeed` process gets killed at startup without a traceback
 
 If the `deepspeed` process gets killed at launch time without a traceback, that usually means that the program tried
 to allocate more CPU memory than your system has or your process is allowed to allocate and the OS kernel killed that
 process. This is because your configuration file most likely has either `offload_optimizer` or `offload_param` or
 both configured to offload to `cpu`. If you have NVMe, experiment with offloading to NVMe if you're running under
-ZeRO-3.

+ZeRO-3. Here is how you can [estimate how much memory is needed for a specific model](https://deepspeed.readthedocs.io/en/latest/memory.html).
 
 
+#### training and/or eval/predict loss is `NaN`
 
+This often happens when one takes a model pre-trained in bf16 mixed precision mode and tries to use it under fp16 (with or without mixed precision). Most models trained on TPU and often the ones released by Google are in this category (e.g. almost all t5-based models). Here the solution is to either use fp32 or bf16 if your hardware supports it (TPU, Ampere GPUs or newer).
+
+The other problem may have to do with using fp16. When you configure this section:
+
+```json
+{
+    "fp16": {
+        "enabled": "auto",
+        "loss_scale": 0,
+        "loss_scale_window": 1000,
+        "initial_scale_power": 16,
+        "hysteresis": 2,
+        "min_loss_scale": 1
+    }
+}
+```
+
+and you see in your log that Deepspeed reports `OVERFLOW!` as follows:
+
+```
+0%|                                                                                                                             | 0/189 [00:00<?, ?it/s]

+(the log was massaged to be more readable here.)

+### Custom DeepSpeed ZeRO Inference
+
+Here is an example of how one could do DeepSpeed ZeRO Inference without using [`Trainer`] when one can't fit a model onto a single GPU. The solution includes using additional GPUs or/and offloading GPU memory to CPU memory.
+
+The important nuance to understand here is that the way ZeRO is designed you can process different inputs on different GPUs in parallel.
+
+The example has copious notes and is self-documenting.
+
+Make sure to:
+
+1. disable CPU offload if you have enough GPU memory (since it slows things down)
+2. enable bf16 if you own an Ampere or a newer GPU to make things faster. If you don't have that hardware you may enable fp16 as long as you don't use any model that was pre-trained in bf16 mixed precision (such as most t5 models). These usually overflow in fp16 and you will see garbage as output.
+
+```python
+#!/usr/bin/env python
+
+# This script demonstrates how to use Deepspeed ZeRO in an inference mode when one can't fit a model
+# into a single GPU
+#
+# 1. Use 1 GPU with CPU offload
+# 2. Or use multiple GPUs instead
+#
+# First you need to install deepspeed: pip install deepspeed
+#
+# Here we use a 3B "bigscience/T0_3B" model which needs about 15GB GPU RAM - so 1 largish or 2
+# small GPUs can handle it. or 1 small GPU and a lot of CPU memory.
+#
+# To use a larger model like "bigscience/T0" which needs about 50GB, unless you have an 80GB GPU -
+# you will need 2-4 gpus. And then you can adapt the script to handle more gpus if you want to
+# process multiple inputs at once.
+#
+# The provided deepspeed config also activates CPU memory offloading, so chances are that if you
+# have a lot of available CPU memory and you don't mind a slowdown you should be able to load a
+# model that doesn't normally fit into a single GPU. If you have enough GPU memory the program will
+# run faster if you don't want offload to CPU - so disable that section then.
+#
+# To deploy on 1 gpu:
+#
+# deepspeed --num_gpus 1 t0.py
+# or:
+# python -m torch.distributed.run --nproc_per_node=1 t0.py
+#

+# Logging
+
+🤗 Transformers has a centralized logging system, so that you can setup the verbosity of the library easily.
+
+Currently the default verbosity of the library is `WARNING`.
+
+To change the level of verbosity, just use one of the direct setters. For instance, here is how to change the verbosity
+to the INFO level.
+
+```python
+import transformers
+
+transformers.logging.set_verbosity_info()
+```
+
+You can also use the environment variable `TRANSFORMERS_VERBOSITY` to override the default verbosity. You can set it
+to one of the following: `debug`, `info`, `warning`, `error`, `critical`. For example:
+
+```bash
+TRANSFORMERS_VERBOSITY=error ./myprogram.py
+```
+
+Additionally, some `warnings` can be disabled by setting the environment variable
+`TRANSFORMERS_NO_ADVISORY_WARNINGS` to a true value, like *1*. This will disable any warning that is logged using
+[`logger.warning_advice`]. For example:
+
+```bash
+TRANSFORMERS_NO_ADVISORY_WARNINGS=1 ./myprogram.py
+```
+
+Here is an example of how to use `logging` in a module:
+
+```python
+from transformers.utils import logging
+
+logging.set_verbosity_info()
+logger = logging.get_logger(__name__)
+logger.info("INFO")
+logger.warning("WARN")
+```
+
+Above, a `logger` instance is created from `logging.get_logger(__name__)`. If you want to use `logging` in a script, you shouldn't pass `__name__` to `logging.get_logger`. For example:
+
+```python
+from transformers.utils import logging
+
+if __name__ == "__main__":
+    logging.set_verbosity_info()
+    # leave it empy or use a string
+    logger = logging.get_logger()
+    logger.info("INFO")
+    logger.warning("WARN")
+```
+
+All the methods of this logging module are documented below, the main ones are
+[`logging.get_verbosity`] to get the current level of verbosity in the logger and
+[`logging.set_verbosity`] to set the verbosity to the level of your choice. In order (from the least
+verbose to the most verbose), those levels (with their corresponding int values in parenthesis) are:
+
+- `transformers.logging.CRITICAL` or `transformers.logging.FATAL` (int value, 50): only report the most
+  critical errors.
+- `transformers.logging.ERROR` (int value, 40): only report errors.
+- `transformers.logging.WARNING` or `transformers.logging.WARN` (int value, 30): only reports error and
+  warnings. This the default level used by the library.
+- `transformers.logging.INFO` (int value, 20): reports error, warnings and basic information.
+- `transformers.logging.DEBUG` (int value, 10): report all information.
+
+By default, `tqdm` progress bars will be displayed during model download. [`logging.disable_progress_bar`] and [`logging.enable_progress_bar`] can be used to suppress or unsuppress this behavior.

-:meth:`logger.warning_advice`. For example:
-
-
-.. code-block:: bash
-
-    TRANSFORMERS_NO_ADVISORY_WARNINGS=1 ./myprogram.py
-
-All the methods of this logging module are documented below, the main ones are
-:func:`transformers.logging.get_verbosity` to get the current level of verbosity in the logger and
-:func:`transformers.logging.set_verbosity` to set the verbosity to the level of your choice. In order (from the least
-verbose to the most verbose), those levels (with their corresponding int values in parenthesis) are:
-
-- :obj:`transformers.logging.CRITICAL` or :obj:`transformers.logging.FATAL` (int value, 50): only report the most
-  critical errors.
-- :obj:`transformers.logging.ERROR` (int value, 40): only report errors.
-- :obj:`transformers.logging.WARNING` or :obj:`transformers.logging.WARN` (int value, 30): only reports error and
-  warnings. This the default level used by the library.
-- :obj:`transformers.logging.INFO` (int value, 20): reports error, warnings and basic information.
-- :obj:`transformers.logging.DEBUG` (int value, 10): report all information.

+# Models
+
+The base classes [`PreTrainedModel`], [`TFPreTrainedModel`], and
+[`FlaxPreTrainedModel`] implement the common methods for loading/saving a model either from a local
+file or directory, or from a pretrained model configuration provided by the library (downloaded from HuggingFace's AWS
+S3 repository).
+
+[`PreTrainedModel`] and [`TFPreTrainedModel`] also implement a few methods which
+are common among all the models to:
+
+- resize the input token embeddings when new tokens are added to the vocabulary
+- prune the attention heads of the model.
+
+The other methods that are common to each model are defined in [`~modeling_utils.ModuleUtilsMixin`]
+(for the PyTorch models) and [`~modeling_tf_utils.TFModuleUtilsMixin`] (for the TensorFlow models) or
+for text generation, [`~generation_utils.GenerationMixin`] (for the PyTorch models),
+[`~generation_tf_utils.TFGenerationMixin`] (for the TensorFlow models) and
+[`~generation_flax_utils.FlaxGenerationMixin`] (for the Flax/JAX models).

+### Model Instantiation dtype
+
+Under Pytorch a model normally gets instantiated with `torch.float32` format. This can be an issue if one tries to
+load a model whose weights are in fp16, since it'd require twice as much memory. To overcome this limitation, you can
+either explicitly pass the desired `dtype` using `torch_dtype` argument:
+
+```python
+model = T5ForConditionalGeneration.from_pretrained("t5", torch_dtype=torch.float16)
+```
+
+or, if you want the model to always load in the most optimal memory pattern, you can use the special value `"auto"`,
+and then `dtype` will be automatically derived from the model's weights:
+
+```python
+model = T5ForConditionalGeneration.from_pretrained("t5", torch_dtype="auto")
+```
+
+Models instantiated from scratch can also be told which `dtype` to use with:
+
+```python
+config = T5Config.from_pretrained("t5")
+model = AutoModel.from_config(config)
+```
+
+Due to Pytorch design, this functionality is only available for floating dtypes.

+# Exporting 🤗 Transformers models to ONNX
+
+🤗 Transformers provides a `transformers.onnx` package that enables you to
+convert model checkpoints to an ONNX graph by leveraging configuration objects.
+
+See the [guide](../serialization) on exporting 🤗 Transformers models for more
+details.
+
+## ONNX Configurations
+
+We provide three abstract classes that you should inherit from, depending on the
+type of model architecture you wish to export:
+
+* Encoder-based models inherit from [`~onnx.config.OnnxConfig`]
+* Decoder-based models inherit from [`~onnx.config.OnnxConfigWithPast`]
+* Encoder-decoder models inherit from [`~onnx.config.OnnxSeq2SeqConfigWithPast`]
+
+### OnnxConfig
+
+[[autodoc]] onnx.config.OnnxConfig
+
+### OnnxConfigWithPast
+
+[[autodoc]] onnx.config.OnnxConfigWithPast
+
+### OnnxSeq2SeqConfigWithPast
+
+[[autodoc]] onnx.config.OnnxSeq2SeqConfigWithPast
+
+## ONNX Features
+
+Each ONNX configuration is associated with a set of _features_ that enable you
+to export models for different types of topologies or tasks.

+# Model outputs
+
+All models have outputs that are instances of subclasses of [`~file_utils.ModelOutput`]. Those are
+data structures containing all the information returned by the model, but that can also be used as tuples or
+dictionaries.
+
+Let's see of this looks on an example:
+
+```python
+from transformers import BertTokenizer, BertForSequenceClassification
+import torch
+
+tokenizer = BertTokenizer.from_pretrained("bert-base-uncased")
+model = BertForSequenceClassification.from_pretrained("bert-base-uncased")
+
+inputs = tokenizer("Hello, my dog is cute", return_tensors="pt")
+labels = torch.tensor([1]).unsqueeze(0)  # Batch size 1
+outputs = model(**inputs, labels=labels)
+```
+
+The `outputs` object is a [`~modeling_outputs.SequenceClassifierOutput`], as we can see in the
+documentation of that class below, it means it has an optional `loss`, a `logits` an optional `hidden_states` and
+an optional `attentions` attribute. Here we have the `loss` since we passed along `labels`, but we don't have
+`hidden_states` and `attentions` because we didn't pass `output_hidden_states=True` or
+`output_attentions=True`.
+
+You can access each attribute as you would usually do, and if that attribute has not been returned by the model, you
+will get `None`. Here for instance `outputs.loss` is the loss computed by the model, and `outputs.attentions` is
+`None`.
+
+When considering our `outputs` object as tuple, it only considers the attributes that don't have `None` values.
+Here for instance, it has two elements, `loss` then `logits`, so
+
+```python
+outputs[:2]
+```
+
+will return the tuple `(outputs.loss, outputs.logits)` for instance.
+
+When considering our `outputs` object as dictionary, it only considers the attributes that don't have `None`
+values. Here for instance, it has two keys that are `loss` and `logits`.
+
+We document here the generic model outputs that are used by more than one model type. Specific output types are
+documented on their corresponding model page.

-Model outputs
------------------------------------------------------------------------------------------------------------------------
-
-All models have outputs that are instances of subclasses of :class:`~transformers.file_utils.ModelOutput`. Those are
-data structures containing all the information returned by the model, but that can also be used as tuples or
-dictionaries.
-
-Let's see of this looks on an example:
-
-.. code-block::
-
-    from transformers import BertTokenizer, BertForSequenceClassification
-    import torch
-
-    tokenizer = BertTokenizer.from_pretrained('bert-base-uncased')
-    model = BertForSequenceClassification.from_pretrained('bert-base-uncased')
-
-    inputs = tokenizer("Hello, my dog is cute", return_tensors="pt")
-    labels = torch.tensor([1]).unsqueeze(0)  # Batch size 1
-    outputs = model(**inputs, labels=labels)
-
-The ``outputs`` object is a :class:`~transformers.modeling_outputs.SequenceClassifierOutput`, as we can see in the
-documentation of that class below, it means it has an optional ``loss``, a ``logits`` an optional ``hidden_states`` and
-an optional ``attentions`` attribute. Here we have the ``loss`` since we passed along ``labels``, but we don't have
-``hidden_states`` and ``attentions`` because we didn't pass ``output_hidden_states=True`` or
-``output_attentions=True``.
-
-You can access each attribute as you would usually do, and if that attribute has not been returned by the model, you
-will get ``None``. Here for instance ``outputs.loss`` is the loss computed by the model, and ``outputs.attentions`` is
-``None``.
-
-When considering our ``outputs`` object as tuple, it only considers the attributes that don't have ``None`` values.
-Here for instance, it has two elements, ``loss`` then ``logits``, so
-
-.. code-block::
-
-    outputs[:2]
-
-will return the tuple ``(outputs.loss, outputs.logits)`` for instance.
-
-When considering our ``outputs`` object as dictionary, it only considers the attributes that don't have ``None``
-values. Here for instance, it has two keys that are ``loss`` and ``logits``.
-
-We document here the generic model outputs that are used by more than one model type. Specific output types are
-documented on their corresponding model page.

+# Pipelines
+
+The pipelines are a great and easy way to use models for inference. These pipelines are objects that abstract most of
+the complex code from the library, offering a simple API dedicated to several tasks, including Named Entity
+Recognition, Masked Language Modeling, Sentiment Analysis, Feature Extraction and Question Answering. See the
+[task summary](../task_summary) for examples of use.
+
+There are two categories of pipeline abstractions to be aware about:
+
+- The [`pipeline`] which is the most powerful object encapsulating all other pipelines.
+- The other task-specific pipelines:
+
+  - [`AudioClassificationPipeline`]
+  - [`AutomaticSpeechRecognitionPipeline`]
+  - [`ConversationalPipeline`]
+  - [`FeatureExtractionPipeline`]
+  - [`FillMaskPipeline`]
+  - [`ImageClassificationPipeline`]
+  - [`ImageSegmentationPipeline`]
+  - [`ObjectDetectionPipeline`]
+  - [`QuestionAnsweringPipeline`]
+  - [`SummarizationPipeline`]
+  - [`TableQuestionAnsweringPipeline`]
+  - [`TextClassificationPipeline`]
+  - [`TextGenerationPipeline`]
+  - [`Text2TextGenerationPipeline`]
+  - [`TokenClassificationPipeline`]
+  - [`TranslationPipeline`]
+  - [`ZeroShotClassificationPipeline`]
+
+## The pipeline abstraction
+
+The *pipeline* abstraction is a wrapper around all the other available pipelines. It is instantiated as any other
+pipeline but can provide additional quality of life.
+
+Simple call on one item:
+
+```python
+>>> pipe = pipeline("text-classification")
+>>> pipe("This restaurant is awesome")
+[{'label': 'POSITIVE', 'score': 0.9998743534088135}]
+```
+
+If you want to use a specific model from the [hub](https://huggingface.co) you can ignore the task if the model on
+the hub already defines it:
+
+```python
+>>> pipe = pipeline(model="roberta-large-mnli")
+>>> pipe("This restaurant is awesome")
+[{'label': 'POSITIVE', 'score': 0.9998743534088135}]
+```
+
+To call a pipeline on many items, you can either call with a *list*.
+
+```python
+>>> pipe = pipeline("text-classification")
+>>> pipe(["This restaurant is awesome", "This restaurant is aweful"])
+[{'label': 'POSITIVE', 'score': 0.9998743534088135},
+ {'label': 'NEGATIVE', 'score': 0.9996669292449951}]
+```
+
+To iterate of full datasets it is recommended to use a `dataset` directly. This means you don't need to allocate
+the whole dataset at once, nor do you need to do batching yourself. This should work just as fast as custom loops on
+GPU. If it doesn't don't hesitate to create an issue.
+
+```python
+import datasets
+from transformers import pipeline
+from transformers.pipelines.pt_utils import KeyDataset
+from tqdm.auto import tqdm
+
+pipe = pipeline("automatic-speech-recognition", model="facebook/wav2vec2-base-960h", device=0)
+dataset = datasets.load_dataset("superb", name="asr", split="test")
+
+# KeyDataset (only *pt*) will simply return the item in the dict returned by the dataset item
+# as we're not interested in the *target* part of the dataset.
+for out in tqdm(pipe(KeyDataset(dataset, "file"))):
+    print(out)
+    # {"text": "NUMBER TEN FRESH NELLY IS WAITING ON YOU GOOD NIGHT HUSBAND"}
+    # {"text": ....}
+    # ....
+```
+
+For ease of use, a generator is also possible:
+
+
+```python
+from transformers import pipeline
+
+pipe = pipeline("text-classification")
+
+
+def data():
+    while True:
+        # This could come from a dataset, a database, a queue or HTTP request
+        # in a server
+        # Caveat: because this is iterative, you cannot use `num_workers > 1` variable
+        # to use multiple threads to preprocess data. You can still have 1 thread that
+        # does the preprocessing while the main runs the big inference
+        yield "This is a test"
+
+
+for out in pipe(data()):
+    print(out)
+    # {"text": "NUMBER TEN FRESH NELLY IS WAITING ON YOU GOOD NIGHT HUSBAND"}
+    # {"text": ....}
+    # ....
+```
+
+[[autodoc]] pipeline
+
+## Pipeline batching
+
+All pipelines can use batching. This will work
+whenever the pipeline uses its streaming ability (so when passing lists or `Dataset` or `generator`).
+
+```python
+from transformers import pipeline
+from transformers.pipelines.pt_utils import KeyDataset
+import datasets
+
+dataset = datasets.load_dataset("imdb", name="plain_text", split="unsupervised")
+pipe = pipeline("text-classification", device=0)
+for out in pipe(KeyDataset(dataset, "text"), batch_size=8, truncation="only_first"):
+    print(out)
+    # [{'label': 'POSITIVE', 'score': 0.9998743534088135}]
+    # Exactly the same output as before, but the content are passed
+    # as batches to the model
+```
+
+<Tip warning={true}>
+
+However, this is not automatically a win for performance. It can be either a 10x speedup or 5x slowdown depending
+on hardware, data and the actual model being used.
+
+Example where it's mostly a speedup:
+
+</Tip>
+
+```python
+from transformers import pipeline
+from torch.utils.data import Dataset
+from tqdm.auto import tqdm
+
+pipe = pipeline("text-classification", device=0)
+
+
+class MyDataset(Dataset):
+    def __len__(self):
+        return 5000
+
+    def __getitem__(self, i):
+        return "This is a test"
+
+
+dataset = MyDataset()
+
+for batch_size in [1, 8, 64, 256]:
+    print("-" * 30)
+    print(f"Streaming batch_size={batch_size}")
+    for out in tqdm(pipe(dataset, batch_size=batch_size), total=len(dataset)):
+        pass
+```

+        else:
+            n = 1
+        return "This is a test" * n
+```
+
+This is a occasional very long sentence compared to the other. In that case, the **whole** batch will need to be 400
+tokens long, so the whole batch will be [64, 400] instead of [64, 4], leading to the high slowdown. Even worse, on
+bigger batches, the program simply crashes.

+
+There are no good (general) solutions for this problem, and your mileage may vary depending on your use cases. Rule of
+thumb:
+
+For users, a rule of thumb is:
+
+- **Measure performance on your load, with your hardware. Measure, measure, and keep measuring. Real numbers are the
+  only way to go.**
+- If you are latency constrained (live product doing inference), don't batch
+- If you are using CPU, don't batch.
+- If you are using throughput (you want to run your model on a bunch of static data), on GPU, then:
+
+  - If you have no clue about the size of the sequence_length ("natural" data), by default don't batch, measure and
+    try tentatively to add it, add OOM checks to recover when it will fail (and it will at some point if you don't
+    control the sequence_length.)
+  - If your sequence_length is super regular, then batching is more likely to be VERY interesting, measure and push
+    it until you get OOMs.
+  - The larger the GPU the more likely batching is going to be more interesting
+- As soon as you enable batching, make sure you can handle OOMs nicely.
+
+## Pipeline chunk batching
+
+`zero-shot-classification` and `question-answering` are slightly specific in the sense, that a single input might yield
+multiple forward pass of a model. Under normal circumstances, this would yield issues with `batch_size` argument.
+
+In order to circumvent this issue, both of these pipelines are a bit specific, they are `ChunkPipeline` instead of
+regular `Pipeline`. In short:
+
+
+```python
+preprocessed = pipe.preprocess(inputs)
+model_outputs = pipe.forward(preprocessed)
+outputs = pipe.postprocess(model_outputs)
+```
+
+Now becomes:
+
+
+```python
+all_model_outputs = []
+for preprocessed in pipe.preprocess(inputs):
+    model_outputs = pipe.forward(preprocessed)
+    all_model_outputs.append(model_outputs)
+outputs = pipe.postprocess(all_model_outputs)
+```
+
+This should be very transparent to your code because the pipelines are used in
+the same way.
+
+This is a simplified view, since the pipeline can handle automatically the batch to ! Meaning you don't have to care
+about how many forward passes you inputs are actually going to trigger, you can optimize the `batch_size`
+independently of the inputs. The caveats from the previous section still apply.
+
+## Pipeline custom code
+
+If you want to override a specific pipeline.
+
+Don't hesitate to create an issue for your task at hand, the goal of the pipeline is to be easy to use and support most
+cases, so `transformers` could maybe support your use case.
+
+
+If you want to try simply you can:
+
+- Subclass your pipeline of choice
+
+```python
+class MyPipeline(TextClassificationPipeline):
+    def postprocess():
+        # Your code goes here
+        scores = scores * 100
+        # And here
+
+
+my_pipeline = MyPipeline(model=model, tokenizer=tokenizer, ...)
+# or if you use *pipeline* function, then:
+my_pipeline = pipeline(model="xxxx", pipeline_class=MyPipeline)
+```
+
+That should enable you to do all the custom code you want.

-Pipelines
------------------------------------------------------------------------------------------------------------------------
-
-The pipelines are a great and easy way to use models for inference. These pipelines are objects that abstract most of
-the complex code from the library, offering a simple API dedicated to several tasks, including Named Entity
-Recognition, Masked Language Modeling, Sentiment Analysis, Feature Extraction and Question Answering. See the
-:doc:`task summary <../task_summary>` for examples of use.
-
-There are two categories of pipeline abstractions to be aware about:
-
-- The :func:`~transformers.pipeline` which is the most powerful object encapsulating all other pipelines.
-- The other task-specific pipelines:
-
-    - :class:`~transformers.AudioClassificationPipeline`
-    - :class:`~transformers.AutomaticSpeechRecognitionPipeline`
-    - :class:`~transformers.ConversationalPipeline`
-    - :class:`~transformers.FeatureExtractionPipeline`
-    - :class:`~transformers.FillMaskPipeline`
-    - :class:`~transformers.ImageClassificationPipeline`
-    - :class:`~transformers.ImageSegmentationPipeline`
-    - :class:`~transformers.ObjectDetectionPipeline`
-    - :class:`~transformers.QuestionAnsweringPipeline`
-    - :class:`~transformers.SummarizationPipeline`
-    - :class:`~transformers.TableQuestionAnsweringPipeline`
-    - :class:`~transformers.TextClassificationPipeline`
-    - :class:`~transformers.TextGenerationPipeline`
-    - :class:`~transformers.Text2TextGenerationPipeline`
-    - :class:`~transformers.TokenClassificationPipeline`
-    - :class:`~transformers.TranslationPipeline`
-    - :class:`~transformers.ZeroShotClassificationPipeline`
-
-The pipeline abstraction
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The `pipeline` abstraction is a wrapper around all the other available pipelines. It is instantiated as any other
-pipeline but can provide additional quality of life.
-
-Simple call on one item:
-
-.. code-block::
-
-    >>> pipe = pipeline("text-classification")
-    >>> pipe("This restaurant is awesome")
-    [{'label': 'POSITIVE', 'score': 0.9998743534088135}]
-
-If you want to use a specific model from the `hub <https://huggingface.co>`__ you can ignore the task if the model on
-the hub already defines it:
-
-.. code-block::
-
-    >>> pipe = pipeline(model="roberta-large-mnli")
-    >>> pipe("This restaurant is awesome")
-    [{'label': 'POSITIVE', 'score': 0.9998743534088135}]
-
-To call a pipeline on many items, you can either call with a `list`.
-
-.. code-block::
-
-    >>> pipe = pipeline("text-classification")
-    >>> pipe(["This restaurant is awesome", "This restaurant is aweful"])
-    [{'label': 'POSITIVE', 'score': 0.9998743534088135},
-     {'label': 'NEGATIVE', 'score': 0.9996669292449951}]
-
-
-To iterate of full datasets it is recommended to use a :obj:`dataset` directly. This means you don't need to allocate
-the whole dataset at once, nor do you need to do batching yourself. This should work just as fast as custom loops on
-GPU. If it doesn't don't hesitate to create an issue.
-
-.. code-block::
-
-    import datasets
-    from transformers import pipeline
-    from transformers.pipelines.base import KeyDataset
-    import tqdm
-
-    pipe = pipeline("automatic-speech-recognition", model="facebook/wav2vec2-base-960h", device=0)
-    dataset = datasets.load_dataset("superb", name="asr", split="test")
-
-    # KeyDataset (only `pt`) will simply return the item in the dict returned by the dataset item
-    # as we're not interested in the `target` part of the dataset.
-    for out in tqdm.tqdm(pipe(KeyDataset(dataset, "file"))):
-        print(out)
-        # {"text": "NUMBER TEN FRESH NELLY IS WAITING ON YOU GOOD NIGHT HUSBAND"}
-        # {"text": ....}
-        # ....
-
-
-.. autofunction:: transformers.pipeline
-
-Pipeline batching
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-All pipelines (except `zero-shot-classification` and `question-answering` currently) can use batching. This will work
-whenever the pipeline uses its streaming ability (so when passing lists or :obj:`Dataset`).
-
-.. code-block::
-
-    from transformers import pipeline                                                   
-    from transformers.pipelines.base import KeyDataset
-    import datasets
-    import tqdm                                                                         
-
-    dataset = datasets.load_dataset("imdb", name="plain_text", split="unsupervised")
-    pipe = pipeline("text-classification", device=0)
-    for out in pipe(KeyDataset(dataset, "text"), batch_size=8, truncation="only_first"):
-        print(out)
-        # [{'label': 'POSITIVE', 'score': 0.9998743534088135}]
-        # Exactly the same output as before, but the content are passed
-        # as batches to the model
-
-
-.. warning::
-
-    However, this is not automatically a win for performance. It can be either a 10x speedup or 5x slowdown depending
-    on hardware, data and the actual model being used.
-
-    Example where it's most a speedup:
-
-
-.. code-block::
-
-    from transformers import pipeline

-    pipe = pipeline("text-classification", device=0)

-
-This is a occasional very long sentence compared to the other. In that case, the **whole** batch will need to be 400
-tokens long, so the whole batch will be [64, 400] instead of [64, 4], leading to the high slowdown. Even worse, on
-bigger batches, the program simply crashes.

-
-There are no good (general) solutions for this problem, and your mileage may vary depending on your use cases. Rule of
-thumb:
-
-For users, a rule of thumb is:
-
-- **Measure performance on your load, with your hardware. Measure, measure, and keep measuring. Real numbers are the
-  only way to go.**
-- If you are latency constrained (live product doing inference), don't batch
-- If you are using CPU, don't batch.
-- If you are using throughput (you want to run your model on a bunch of static data), on GPU, then:
-
-      - If you have no clue about the size of the sequence_length ("natural" data), by default don't batch, measure and
-        try tentatively to add it, add OOM checks to recover when it will fail (and it will at some point if you don't
-        control the sequence_length.)
-      - If your sequence_length is super regular, then batching is more likely to be VERY interesting, measure and push
-        it until you get OOMs.
-      - The larger the GPU the more likely batching is going to be more interesting
-- As soon as you enable batching, make sure you can handle OOMs nicely.

-Pipeline custom code
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If you want to override a specific pipeline.
-
-Don't hesitate to create an issue for your task at hand, the goal of the pipeline is to be easy to use and support most
-cases, so :obj:`transformers` could maybe support your use case.
-
-
-If you want to try simply you can:
-
-- Subclass your pipeline of choice
-
-.. code-block::
-
-    class MyPipeline(TextClassificationPipeline):
-        def postprocess(...):
-            ...
-            scores = scores * 100
-            ...
-
-    my_pipeline = MyPipeline(model=model, tokenizer=tokenizer, ...)
-    # or if you use `pipeline` function, then:
-    my_pipeline = pipeline(model="xxxx", pipeline_class=MyPipeline)
-
-That should enable you to do all the custom code you want.

+# Processors
+
+Processors can mean two different things in the Transformers library:
+- the objects that pre-process inputs for multi-modal models such as [Wav2Vec2](../model_doc/wav2vec2) (speech and text)
+  or [CLIP](../model_doc/clip) (text and vision)
+- deprecated objects that were used in older versions of the library to preprocess data for GLUE or SQUAD.
+
+## Multi-modal processors
+
+Any multi-modal model will require an object to encode or decode the data that groups several modalities (among text,
+vision and audio). This is handled by objects called processors, which group tokenizers (for the text modality) and
+feature extractors (for vision and audio).
+
+Those processors inherit from the following base class that implements the saving and loading functionality:
+
+[[autodoc]] ProcessorMixin
+
+## Deprecated processors
+
+All processors follow the same architecture which is that of the
+[`~data.processors.utils.DataProcessor`]. The processor returns a list of
+[`~data.processors.utils.InputExample`]. These
+[`~data.processors.utils.InputExample`] can be converted to
+[`~data.processors.utils.InputFeatures`] in order to be fed to the model.

+
+## GLUE
+
+[General Language Understanding Evaluation (GLUE)](https://gluebenchmark.com/) is a benchmark that evaluates the
+performance of models across a diverse set of existing NLU tasks. It was released together with the paper [GLUE: A
+multi-task benchmark and analysis platform for natural language understanding](https://openreview.net/pdf?id=rJ4km2R5t7)
+
+This library hosts a total of 10 processors for the following tasks: MRPC, MNLI, MNLI (mismatched), CoLA, SST2, STSB,
+QQP, QNLI, RTE and WNLI.
+
+Those processors are:
+
+- [`~data.processors.utils.MrpcProcessor`]
+- [`~data.processors.utils.MnliProcessor`]
+- [`~data.processors.utils.MnliMismatchedProcessor`]
+- [`~data.processors.utils.Sst2Processor`]
+- [`~data.processors.utils.StsbProcessor`]
+- [`~data.processors.utils.QqpProcessor`]
+- [`~data.processors.utils.QnliProcessor`]
+- [`~data.processors.utils.RteProcessor`]
+- [`~data.processors.utils.WnliProcessor`]
+
+Additionally, the following method can be used to load values from a data file and convert them to a list of
+[`~data.processors.utils.InputExample`].

+
+
+## XNLI
+
+[The Cross-Lingual NLI Corpus (XNLI)](https://www.nyu.edu/projects/bowman/xnli/) is a benchmark that evaluates the
+quality of cross-lingual text representations. XNLI is crowd-sourced dataset based on [*MultiNLI*](http://www.nyu.edu/projects/bowman/multinli/): pairs of text are labeled with textual entailment annotations for 15

+## SQuAD
+
+[The Stanford Question Answering Dataset (SQuAD)](https://rajpurkar.github.io/SQuAD-explorer//) is a benchmark that
+evaluates the performance of models on question answering. Two versions are available, v1.1 and v2.0. The first version
+(v1.1) was released together with the paper [SQuAD: 100,000+ Questions for Machine Comprehension of Text](https://arxiv.org/abs/1606.05250). The second version (v2.0) was released alongside the paper [Know What You Don't
+Know: Unanswerable Questions for SQuAD](https://arxiv.org/abs/1806.03822).
+
+This library hosts a processor for each of the two versions:
+
+### Processors
+
+Those processors are:
+
+- [`~data.processors.utils.SquadV1Processor`]
+- [`~data.processors.utils.SquadV2Processor`]
+
+They both inherit from the abstract class [`~data.processors.utils.SquadProcessor`]
+
+[[autodoc]] data.processors.squad.SquadProcessor
+    - all
+
+Additionally, the following method can be used to convert SQuAD examples into
+[`~data.processors.utils.SquadFeatures`] that can be used as model inputs.
+
+[[autodoc]] data.processors.squad.squad_convert_examples_to_features
+
+
+These processors as well as the aforementionned method can be used with files containing the data as well as with the
+*tensorflow_datasets* package. Examples are given below.
+
+
+### Example usage
+
+Here is an example using the processors as well as the conversion method using data files:
+
+```python
+# Loading a V2 processor
+processor = SquadV2Processor()
+examples = processor.get_dev_examples(squad_v2_data_dir)
+
+# Loading a V1 processor
+processor = SquadV1Processor()
+examples = processor.get_dev_examples(squad_v1_data_dir)
+
+features = squad_convert_examples_to_features(
+    examples=examples,
+    tokenizer=tokenizer,
+    max_seq_length=max_seq_length,
+    doc_stride=args.doc_stride,
+    max_query_length=max_query_length,
+    is_training=not evaluate,
+)
+```
+
+Using *tensorflow_datasets* is as easy as using a data file:
+
+```python
+# tensorflow_datasets only handle Squad V1.
+tfds_examples = tfds.load("squad")
+examples = SquadV1Processor().get_examples_from_dataset(tfds_examples, evaluate=evaluate)
+
+features = squad_convert_examples_to_features(
+    examples=examples,
+    tokenizer=tokenizer,
+    max_seq_length=max_seq_length,
+    doc_stride=args.doc_stride,
+    max_query_length=max_query_length,
+    is_training=not evaluate,
+)
+```
+
+Another example using these processors is given in the [run_squad.py](https://github.com/huggingface/transformers/tree/master/examples/legacy/question-answering/run_squad.py) script.

+# Tokenizer
+
+A tokenizer is in charge of preparing the inputs for a model. The library contains tokenizers for all the models. Most
+of the tokenizers are available in two flavors: a full python implementation and a "Fast" implementation based on the
+Rust library [🤗 Tokenizers](https://github.com/huggingface/tokenizers). The "Fast" implementations allows:
+
+1. a significant speed-up in particular when doing batched tokenization and
+2. additional methods to map between the original string (character and words) and the token space (e.g. getting the
+   index of the token comprising a given character or the span of characters corresponding to a given token). Currently
+   no "Fast" implementation is available for the SentencePiece-based tokenizers (for T5, ALBERT, CamemBERT, XLM-RoBERTa
+   and XLNet models).
+
+The base classes [`PreTrainedTokenizer`] and [`PreTrainedTokenizerFast`]
+implement the common methods for encoding string inputs in model inputs (see below) and instantiating/saving python and
+"Fast" tokenizers either from a local file or directory or from a pretrained tokenizer provided by the library
+(downloaded from HuggingFace's AWS S3 repository). They both rely on
+[`~tokenization_utils_base.PreTrainedTokenizerBase`] that contains the common methods, and
+[`~tokenization_utils_base.SpecialTokensMixin`].
+
+[`PreTrainedTokenizer`] and [`PreTrainedTokenizerFast`] thus implement the main
+methods for using all the tokenizers:
+
+- Tokenizing (splitting strings in sub-word token strings), converting tokens strings to ids and back, and
+  encoding/decoding (i.e., tokenizing and converting to integers).
+- Adding new tokens to the vocabulary in a way that is independent of the underlying structure (BPE, SentencePiece...).
+- Managing special tokens (like mask, beginning-of-sentence, etc.): adding them, assigning them to attributes in the
+  tokenizer for easy access and making sure they are not split during tokenization.
+
+[`BatchEncoding`] holds the output of the
+[`~tokenization_utils_base.PreTrainedTokenizerBase`]'s encoding methods (`__call__`,
+`encode_plus` and `batch_encode_plus`) and is derived from a Python dictionary. When the tokenizer is a pure python
+tokenizer, this class behaves just like a standard python dictionary and holds the various model inputs computed by
+these methods (`input_ids`, `attention_mask`...). When the tokenizer is a "Fast" tokenizer (i.e., backed by
+HuggingFace [tokenizers library](https://github.com/huggingface/tokenizers)), this class provides in addition
+several advanced alignment methods which can be used to map between the original string (character and words) and the
+token space (e.g., getting the index of the token comprising a given character or the span of characters corresponding
+to a given token).

+## Specific GPUs Selection
+
+Let's discuss how you can tell your program which GPUs are to be used and in what order.
+
+When using [`DistributedDataParallel`](https://pytorch.org/docs/stable/generated/torch.nn.parallel.DistributedDataParallel.html) to use only a subset of your GPUs, you simply specify the number of GPUs to use. For example, if you have 4 GPUs, but you wish to use the first 2 you can do:
+
+```bash
+python -m torch.distributed.launch --nproc_per_node=2  trainer-program.py ...
+```
+
+if you have either [`accelerate`](https://github.com/huggingface/accelerate) or [`deepspeed`](https://github.com/microsoft/DeepSpeed) installed you can also accomplish the same by using one of:
+```bash
+accelerate launch --num_processes 2 trainer-program.py ...
+```
+
+```bash
+deepspeed --num_gpus 2 trainer-program.py ...
+```
+
+You don't need to use the Accelerate or [the Deepspeed integration](Deepspeed) features to use these launchers.
+
+
+Until now you were able to tell the program how many GPUs to use. Now let's discuss how to select specific GPUs and control their order.
+
+The following environment variables help you control which GPUs to use and their order.
+
+**`CUDA_VISIBLE_DEVICES`**
+
+If you have multiple GPUs and you'd like to use only 1 or a few of those GPUs, set the environment variable `CUDA_VISIBLE_DEVICES` to a list of the GPUs to be used.
+
+For example, let's say you have 4 GPUs: 0, 1, 2 and 3. To run only on the physical GPUs 0 and 2, you can do:
+
+```bash
+CUDA_VISIBLE_DEVICES=0,2 python -m torch.distributed.launch trainer-program.py ...
+```
+
+So now pytorch will see only 2 GPUs, where your physical GPUs 0 and 2 are mapped to `cuda:0` and `cuda:1` correspondingly.
+
+You can even change their order:
+
+```bash
+CUDA_VISIBLE_DEVICES=2,0 python -m torch.distributed.launch trainer-program.py ...
+```
+
+Here your physical GPUs 0 and 2 are mapped to `cuda:1` and `cuda:0` correspondingly.
+
+The above examples were all for `DistributedDataParallel` use pattern, but the same method works for [`DataParallel`](https://pytorch.org/docs/stable/generated/torch.nn.DataParallel.html) as well:
+```bash
+CUDA_VISIBLE_DEVICES=2,0 python trainer-program.py ...
+```
+
+To emulate an environment without GPUs simply set this environment variable to an empty value like so:
+
+```bash
+CUDA_VISIBLE_DEVICES= python trainer-program.py ...
+```
+
+As with any environment variable you can, of course, export those instead of adding these to the command line, as in:
+
+
+```bash
+export CUDA_VISIBLE_DEVICES=0,2
+python -m torch.distributed.launch trainer-program.py ...
+```
+
+but this approach can be confusing since you may forget you set up the environment variable earlier and not understand why the wrong GPUs are used. Therefore, it's a common practice to set the environment variable just for a specific run on the same command line as it's shown in most examples of this section.
+
+**`CUDA_DEVICE_ORDER`**
+
+There is an additional environment variable `CUDA_DEVICE_ORDER` that controls how the physical devices are ordered. The two choices are:
+
+1. ordered by PCIe bus IDs (matches `nvidia-smi`'s order) - this is the default.
+
+```bash
+export CUDA_DEVICE_ORDER=PCI_BUS_ID
+```
+
+2. ordered by GPU compute capabilities
+
+```bash
+export CUDA_DEVICE_ORDER=FASTEST_FIRST
+```
+
+Most of the time you don't need to care about this environment variable, but it's very helpful if you have a lopsided setup where you have an old and a new GPUs physically inserted in such a way so that the slow older card appears to be first. One way to fix that is to swap the cards. But if you can't swap the cards (e.g., if the cooling of the devices gets impacted) then setting `CUDA_DEVICE_ORDER=FASTEST_FIRST` will always put the newer faster card first. It'll be somewhat confusing though since `nvidia-smi` will still report them in the PCIe order.
+
+The other solution to swapping the order is to use:
+
+```bash
+export CUDA_VISIBLE_DEVICES=1,0
+```
+In this example we are working with just 2 GPUs, but of course the same would apply to as many GPUs as your computer has.
+
+Also if you do set this environment variable it's the best to set it in your `~/.bashrc` file or some other startup config file and forget about it.

+# Auto Classes
+
+In many cases, the architecture you want to use can be guessed from the name or the path of the pretrained model you
+are supplying to the `from_pretrained()` method. AutoClasses are here to do this job for you so that you
+automatically retrieve the relevant model given the name/path to the pretrained weights/config/vocabulary.
+
+Instantiating one of [`AutoConfig`], [`AutoModel`], and
+[`AutoTokenizer`] will directly create a class of the relevant architecture. For instance
+
+
+```python
+model = AutoModel.from_pretrained("bert-base-cased")
+```
+
+will create a model that is an instance of [`BertModel`].
+
+There is one class of `AutoModel` for each task, and for each backend (PyTorch, TensorFlow, or Flax).
+
+## Extending the Auto Classes
+
+Each of the auto classes has a method to be extended with your custom classes. For instance, if you have defined a
+custom class of model `NewModel`, make sure you have a `NewModelConfig` then you can add those to the auto
+classes like this:
+
+```python
+from transformers import AutoConfig, AutoModel
+
+AutoConfig.register("new-model", NewModelConfig)
+AutoModel.register(NewModelConfig, NewModel)
+```
+
+You will then be able to use the auto classes like you would usually do!
+
+<Tip warning={true}>
+
+If your `NewModelConfig` is a subclass of [`~transformer.PretrainedConfig`], make sure its
+`model_type` attribute is set to the same key you use when registering the config (here `"new-model"`).
+
+Likewise, if your `NewModel` is a subclass of [`PreTrainedModel`], make sure its
+`config_class` attribute is set to the same class you use when registering the model (here
+`NewModelConfig`).
