+### Translating the Transformers documentation into your language
+
+As part of our mission to democratize machine learning, we'd love to make the Transformers library available in many more languages! Follow the steps below if you want to help translate the documentation into your language 🙏.
+
+**🗞️ Open an issue**
+
+To get started, navigate to the [Issues](https://github.com/huggingface/transformers/issues) page of this repo and check if anyone else has opened an issue for your language. If not, open a new issue by selecting the "Translation template" from the "New issue" button.
+
+Once an issue exists, post a comment to indicate which chapters you'd like to work on, and we'll add your name to the list.
+
+
+**🍴 Fork the repository**
+
+First, you'll need to [fork the Transformers repo](https://docs.github.com/en/get-started/quickstart/fork-a-repo). You can do this by clicking on the **Fork** button on the top-right corner of this repo's page.
+
+Once you've forked the repo, you'll want to get the files on your local machine for editing. You can do that by cloning the fork with Git as follows:
+
+```bash
+git clone https://github.com/YOUR-USERNAME/transformers.git
+```
+
+**📋 Copy-paste the English version with a new language code**
+
+The documentation files are in one leading directory:
+
+- [`docs/source`](https://github.com/huggingface/transformers/tree/main/docs/source): All the documentation materials are organized here by language.
+
+You'll only need to copy the files in the [`docs/source/en`](https://github.com/huggingface/transformers/tree/main/docs/source/en) directory, so first navigate to your fork of the repo and run the following:
+
+```bash
+cd ~/path/to/transformers/docs
+cp -r source/en source/LANG-ID
+```
+
+Here, `LANG-ID` should be one of the ISO 639-1 or ISO 639-2 language codes -- see [here](https://www.loc.gov/standards/iso639-2/php/code_list.php) for a handy table.
+
+**✍️ Start translating**
+
+The fun part comes - translating the text!
+
+The first thing we recommend is translating the part of the `_toctree.yml` file that corresponds to your doc chapter. This file is used to render the table of contents on the website. 
+
+> 🙋 If the `_toctree.yml` file doesn't yet exist for your language, you can create one by copy-pasting from the English version and deleting the sections unrelated to your chapter. Just make sure it exists in the `docs/source/LANG-ID/` directory!
+
+The fields you should add are `local` (with the name of the file containing the translation; e.g. `autoclass_tutorial`), and `title` (with the title of the doc in your language; e.g. `Load pretrained instances with an AutoClass`) -- as a reference, here is the `_toctree.yml` for [English](https://github.com/huggingface/transformers/blob/main/docs/source/en/_toctree.yml):
+
+```yaml
+- sections:
+  - local: pipeline_tutorial # Do not change this! Use the same name for your .md file
+    title: Pipelines for inference # Translate this!
+    ...
+  title: Tutorials # Translate this!
+```
+
+Once you have translated the `_toctree.yml` file, you can start translating the [MDX](https://mdxjs.com/) files associated with your docs chapter.
+
+> 🙋 If you'd like others to help you with the translation, you can either [open an issue](https://github.com/huggingface/transformers/issues) or tag @[espejelomar](https://twitter.com/espejelomar)
+ on Twitter to gain some visibility.

+# Instantiating a big model
+
+When you want to use a very big pretrained model, one challenge is to minimize the use of the RAM. The usual workflow
+from PyTorch is:
+
+1. Create your model with random weights.
+2. Load your pretrained weights.
+3. Put those pretrained weights in your random model.
+
+Step 1 and 2 both require a full version of the model in memory, which is not a problem in most cases, but if your model starts weighing several GigaBytes, those two copies can make you got our of RAM. Even worse, if you are using `torch.distributed` to launch a distributed training, each process will load the pretrained model and store these two copies in RAM.
+
+<Tip>
+
+Note that the randomly created model is initialized with "empty" tensors, which take the space in memory without filling it (thus the random values are whatever was in this chunk of memory at a given time). The random initialization following the appropriate distribution for the kind of model/parameters instatiated (like a normal distribution for instance) is only performed after step 3 on the non-initialized weights, to be as fast as possible! 
+
+</Tip>
+
+In this guide, we explore the solutions Transformers offer to deal with this issue. Note that this is an area of active development, so the APIs explained here may change slightly in the future.
+
+## Sharded checkpoints
+
+Since version 4.18.0, model checkpoints that end up taking more than 10GB of space are automatically sharded in smaller pieces. In terms of having one single checkpoint when you do `model.save_pretrained(save_dir)`, you will end up with several partial checkpoints (each of which being of size < 10GB) and an index that maps parameter names to the files they are stored in.
+
+You can control the maximum size before sharding with the `max_shard_size` parameter, so for the sake of an example, we'll use a normal-size models with a small shard size: let's take a traditional BERT model.
+
+```py
+from transformers import AutoModel
+
+model = AutoModel.from_pretrained("bert-base-cased")
+```
+
+If you save it using [`~PreTrainedModel.save_pretrained`], you will get a new folder with two files: the config of the model and its weights:
+
+```py
+>>> import os
+>>> import tempfile
+
+>>> with tempfile.TemporaryDirectory() as tmp_dir:
+...     model.save_pretrained(tmp_dir)
+...     print(sorted(os.listdir(tmp_dir)))
+['config.json', 'pytorch_model.bin']
+```
+
+Now let's use a maximum shard size of 200MB:
+
+```py
+>>> with tempfile.TemporaryDirectory() as tmp_dir:
+...     model.save_pretrained(tmp_dir, max_shard_size="200MB")
+...     print(sorted(os.listdir(tmp_dir)))
+['config.json', 'pytorch_model-00001-of-00003.bin', 'pytorch_model-00002-of-00003.bin', 'pytorch_model-00003-of-00003.bin', 'pytorch_model.bin.index.json']
+```
+
+On top of the configuration of the model, we see three different weights files, and an `index.json` file which is our index. A checkpoint like this can be fully reloaded using the [`~PreTrainedModel.from_pretrained`] method:
+
+```py
+>>> with tempfile.TemporaryDirectory() as tmp_dir:
+...     model.save_pretrained(tmp_dir, max_shard_size="200MB")
+...     new_model = AutoModel.from_pretrained(tmp_dir)
+```
+
+The main advantage of doing this for big models is that during step 2 of the workflow shown above, each shard of the checkpoint is loaded after the previous one, capping the memory usage in RAM to the model size plus the size of the biggest shard.
+
+Beind the scenes, the index file is used to determine which keys are in the checkpoint, and where the corresponding weights are stored. We can load that index like any json and get a dictionary:
+
+```py
+>>> import json
+
+>>> with tempfile.TemporaryDirectory() as tmp_dir:
+...     model.save_pretrained(tmp_dir, max_shard_size="200MB")
+...     with open(os.path.join(tmp_dir, "pytorch_model.bin.index.json"), "r") as f:
+...         index = json.load(f)
+
+>>> print(index.keys())
+dict_keys(['metadata', 'weight_map'])
+```
+
+The metadata just consists of the total size of the model for now. We plan to add several other informations in the future:
+
+```py
+>>> index["metadata"]
+{'total_size': 433245184}
+```
+
+The weights map is the main part of this index, which maps each parameter name (as usually found in a PyTorch model `state_dict`) to the file it's stored in:
+
+```py
+>>> index["weight_map"]
+{'embeddings.LayerNorm.bias': 'pytorch_model-00001-of-00003.bin',
+ 'embeddings.LayerNorm.weight': 'pytorch_model-00001-of-00003.bin',
+ ...
+```
+
+If you want to directly load such a sharded checkpoint inside a model without using [`~PreTrainedModel.from_pretrained`] (like you would do `model.load_state_dict()` for a full checkpoint) you should use [`~modeling_utils.load_sharded_checkpoint`]:
+
+```py
+>>> from transformers.modeling_utils import load_sharded_checkpoint
+
+>>> with tempfile.TemporaryDirectory() as tmp_dir:
+...     model.save_pretrained(tmp_dir, max_shard_size="200MB")
+...     load_sharded_checkpoint(model, tmp_dir)
+```
+
+## Low memory loading
+
+Sharded checkpoints reduce the memory usage during step 2 of the worflow mentioned above, but when loadin a pretrained model, why keep the random weights in memory? The option `low_cpu_mem_usage` will destroy the weights of the randomly initialized model, then progressively load the weights inside, then perform a random initialization for potential missing weights (if you are loadding a model with a newly initialized head for a fine-tuning task for instance).
+
+It's very easy to use, just add `low_cpu_mem_usage=True` to your call to [`~PreTrainedModel.from_pretrained`]:
+
+```py
+from transformers import AutoModelForSequenceClas
+
+model = AutoModel.from_pretrained("bert-base-cased", low_cpu_mem_usage=True)
+```
+
+This can be used in conjunction with a sharded checkpoint.

+### PyTorch Fully Sharded Data parallel
+
+To accelerate training huge models on larger batch sizes, we can use a fully sharded data parallel model.
+This type of data parallel paradigm enables fitting more data and larger models by sharding the optimizer states, gradients and parameters.
+To read more about it and the benefits, check out the [Fully Sharded Data Parallel blog](https://pytorch.org/blog/introducing-pytorch-fully-sharded-data-parallel-api/).
+We have integrated the latest PyTorch's Fully Sharded Data Parallel (FSDP) training feature.
+All you need to do is enable it through the config.
+
+**Required PyTorch version for FSDP support**: PyTorch Nightly (or 1.12.0 if you read this after it has been released)
+as the model saving with FSDP activated is only available with recent fixes.
+
+**Usage**:
+
+- Make sure you have added the distributed launcher
+`-m torch.distributed.launch --nproc_per_node=NUMBER_OF_GPUS_YOU_HAVE` if you haven't been using it already.
+
+- **Sharding Strategy**: 
+  - FULL_SHARD : Shards optimizer states + gradients + model parameters across data parallel workers/GPUs.
+  For this, add `--fsdp full_shard` to the command line arguments. 
+  - SHARD_GRAD_OP : Shards optimizer states + gradients across data parallel workers/GPUs.
+    For this, add `--fsdp shard_grad_op` to the command line arguments.
+- To offload the parameters and gradients to the CPU, 
+add `--fsdp "full_shard offload"` or `--fsdp "shard_grad_op offload"` to the command line arguments.
+-  To automatically recursively wrap layers with FSDP using `default_auto_wrap_policy`, 
+add `--fsdp "full_shard auto_wrap"` or `--fsdp "shard_grad_op auto_wrap"` to the command line arguments.
+- To enable both CPU offloading and auto wrapping, 
+add `--fsdp "full_shard offload auto_wrap"` or `--fsdp "shard_grad_op offload auto_wrap"` to the command line arguments.
+- If auto wrapping is enabled, please add `--fsdp_min_num_params <number>` to command line arguments.
+It specifies FSDP's minimum number of parameters for Default Auto Wrapping.
+
+**Few caveats to be aware of**
+- Mixed precision is currently not supported with FSDP as we wait for PyTorch to fix support for it.
+More details in this [issues](https://github.com/pytorch/pytorch/issues/75676).
+- FSDP currently doesn't support multiple parameter groups. 
+More details mentioned in this [issue](https://github.com/pytorch/pytorch/issues/76501)
+(`The original model parameters' .grads are not set, meaning that they cannot be optimized separately (which is why we cannot support multiple parameter groups)`).

+>>> # => Need to shift utf-8 character encodings by 3 before passing ids to model.

+
+>>> loss = model(input_ids, labels=labels).loss
+>>> loss.item()

 ```
 
 For batched inference and training it is however recommended to make use of the tokenizer:
 
 ```python
-from transformers import T5ForConditionalGeneration, AutoTokenizer
+>>> from transformers import T5ForConditionalGeneration, AutoTokenizer
 
-model = T5ForConditionalGeneration.from_pretrained("google/byt5-small")
-tokenizer = AutoTokenizer.from_pretrained("google/byt5-small")
+>>> model = T5ForConditionalGeneration.from_pretrained("google/byt5-small")
+>>> tokenizer = AutoTokenizer.from_pretrained("google/byt5-small")
 
-model_inputs = tokenizer(
-    ["Life is like a box of chocolates.", "Today is Monday."], padding="longest", return_tensors="pt"
-)
-labels = tokenizer(
-    ["La vie est comme une boîte de chocolat.", "Aujourd'hui c'est lundi."], padding="longest", return_tensors="pt"
-).input_ids
+>>> model_inputs = tokenizer(
+...     ["Life is like a box of chocolates.", "Today is Monday."], padding="longest", return_tensors="pt"
+... )
+>>> labels_dict = tokenizer(
+...     ["La vie est comme une boîte de chocolat.", "Aujourd'hui c'est lundi."], padding="longest", return_tensors="pt"
+... )
+>>> labels = labels_dict.input_ids
 
-loss = model(**model_inputs, labels=labels).loss  # forward pass
+>>> loss = model(**model_inputs, labels=labels).loss
+>>> loss.item()
+17.9
 ```
 
+Similar to [T5](t5), ByT5 was trained on the span-mask denoising task. However, 
+since the model works directly on characters, the pretraining task is a bit 
+different. Let's corrupt some characters of the 
+input sentence `"The dog chases a ball in the park."` and ask ByT5 to predict them 
+for us.
+
+```python
+>>> from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
+>>> import torch
+
+>>> tokenizer = AutoTokenizer.from_pretrained("google/byt5-base")
+>>> model = AutoModelForSeq2SeqLM.from_pretrained("google/byt5-base")
+
+>>> input_ids_prompt = "The dog chases a ball in the park."
+>>> input_ids = tokenizer(input_ids_prompt).input_ids
+
+>>> # Note that we cannot add "{extra_id_...}" to the string directly
+>>> # as the Byte tokenizer would incorrectly merge the tokens
+>>> # For ByT5, we need to work directly on the character level
+>>> # Contrary to T5, ByT5 does not use sentinel tokens for masking, but instead
+>>> # uses final utf character ids.
+>>> # UTF-8 is represented by 8 bits and ByT5 has 3 special tokens.
+>>> # => There are 2**8+2 = 259 input ids and mask tokens count down from index 258.
+>>> # => mask to "The dog [258]a ball [257]park."
+
+>>> input_ids = torch.tensor([input_ids[:8] + [258] + input_ids[14:21] + [257] + input_ids[28:]])
+>>> input_ids
+tensor([[ 87, 107, 104,  35, 103, 114, 106,  35, 258,  35, 100,  35, 101, 100, 111, 111, 257,  35, 115, 100, 117, 110,  49,   1]])
+
+>>> # ByT5 produces only one char at a time so we need to produce many more output characters here -> set `max_length=100`.
+>>> output_ids = model.generate(input_ids, max_length=100)[0].tolist()
+>>> output_ids

+# FLAVA
+
+## Overview
+
+The FLAVA model was proposed in [FLAVA: A Foundational Language And Vision Alignment Model](https://arxiv.org/abs/2112.04482) by Amanpreet Singh, Ronghang Hu, Vedanuj Goswami, Guillaume Couairon, Wojciech Galuba, Marcus Rohrbach, and Douwe Kiela and is accepted at CVPR 2022.
+
+The paper aims at creating a single unified foundation model which can work across vision, language 
+as well as vision-and-language multimodal tasks.
+
+The abstract from the paper is the following:
+
+*State-of-the-art vision and vision-and-language models rely on large-scale visio-linguistic pretraining for obtaining good performance on a variety 
+of downstream tasks. Generally, such models are often either cross-modal (contrastive) or multi-modal 
+(with earlier fusion) but not both; and they often only target specific modalities or tasks. A promising 
+direction would be to use a single holistic universal model, as a "foundation", that targets all modalities 
+at once -- a true vision and language foundation model should be good at vision tasks, language tasks, and 
+cross- and multi-modal vision and language tasks. We introduce FLAVA as such a model and demonstrate 
+impressive performance on a wide range of 35 tasks spanning these target modalities.*

+# OPT
+
+## Overview
+
+The OPT model was proposed in [Open Pre-trained Transformer Language Models](https://arxiv.org/pdf/2205.01068) by Meta AI.
+OPT is a series of open-sourced large causal language models which perform similar in performance to GPT3. 
+
+
+The abstract from the paper is the following:
+
+*Large language models, which are often trained for hundreds of thousands of compute days, have shown remarkable capabilities for zero- and few-shot learning. Given their computational cost, these models are difficult to replicate without significant capital. For the few that are available through APIs, no access is granted to the full model weights, making them difficult to study. We present Open Pre-trained Transformers (OPT), a suite of decoder-only pre-trained transformers ranging from 125M to 175B parameters, which we aim to fully and responsibly share with interested researchers. We show that OPT-175B is comparable to GPT-3, while requiring only 1/7th the carbon footprint to develop. We are also releasing our logbook detailing the infrastructure challenges we faced, along with code for experimenting with all of the released models.*
+
+Tips:
+- OPT has the same architecture as [`BartDecoder`].
+- Contrary to GPT2, OPT adds the EOS token `</s>` to the beginning of every prompt. **Note**: Make sure to pass `use_fast=False` when loading OPT's tokenizer with [`AutoTokenizer`] to get the correct tokenizer.

+# RegNet
+
+## Overview
+
+The RegNet model was proposed in [Designing Network Design Spaces](https://arxiv.org/abs/2003.13678) by Ilija Radosavovic, Raj Prateek Kosaraju, Ross Girshick, Kaiming He, Piotr Dollár.
+
+The authors design search spaces to perform Neural Architecture Search (NAS). They first start from a high dimensional search space and iteratively reduce the search space by empirically applying constraints based on the best-performing models sampled by the current search space.
+
+The abstract from the paper is the following:
+
+*In this work, we present a new network design paradigm. Our goal is to help advance the understanding of network design and discover design principles that generalize across settings. Instead of focusing on designing individual network instances, we design network design spaces that parametrize populations of networks. The overall process is analogous to classic manual design of networks, but elevated to the design space level. Using our methodology we explore the structure aspect of network design and arrive at a low-dimensional design space consisting of simple, regular networks that we call RegNet. The core insight of the RegNet parametrization is surprisingly simple: widths and depths of good networks can be explained by a quantized linear function. We analyze the RegNet design space and arrive at interesting findings that do not match the current practice of network design. The RegNet design space provides simple and fast networks that work well across a wide range of flop regimes. Under comparable training settings and flops, the RegNet models outperform the popular EfficientNet models while being up to 5x faster on GPUs.*
+
+Tips:
+
+- One can use [`AutoFeatureExtractor`] to prepare images for the model.
+- The huge 10B model from [Self-supervised Pretraining of Visual Features in the Wild](https://arxiv.org/abs/2103.01988), trained on one billion Instagram images, is available on the [hub](https://huggingface.co/facebook/regnet-y-10b-seer)

-  equal to 0 (i.e. the id of the pad token). Also note the task prefix: we prepend the input sequence with 'translate
-  English to German: ' before encoding it. This will help in improving the performance, as this task prefix was used
-  during T5's pre-training.

-  However, the example above only shows a single training example. In practice, one trains deep learning models in
-  batches. This entails that we must pad/truncate examples to the same length. For encoder-decoder models, one
-  typically defines a `max_source_length` and `max_target_length`, which determine the maximum length of the
-  input and output sequences respectively (otherwise they are truncated). These should be carefully set depending on
-  the task.
+As you can see, only 2 inputs are required for the model in order to compute a loss: `input_ids` (which are the

+# TAPEX
+
+## Overview
+
+The TAPEX model was proposed in [TAPEX: Table Pre-training via Learning a Neural SQL Executor](https://arxiv.org/abs/2107.07653) by Qian Liu,
+Bei Chen, Jiaqi Guo, Morteza Ziyadi, Zeqi Lin, Weizhu Chen, Jian-Guang Lou. TAPEX pre-trains a BART model to solve synthetic SQL queries, after
+which it can be fine-tuned to answer natural language questions related to tabular data, as well as performing table fact checking. 
+
+TAPEX has been fine-tuned on several datasets: 
+- [SQA](https://www.microsoft.com/en-us/download/details.aspx?id=54253) (Sequential Question Answering by Microsoft)
+- [WTQ](https://github.com/ppasupat/WikiTableQuestions) (Wiki Table Questions by Stanford University)
+- [WikiSQL](https://github.com/salesforce/WikiSQL) (by Salesforce)
+- [TabFact](https://tabfact.github.io/) (by USCB NLP Lab).
+
+The abstract from the paper is the following:
+
+*Recent progress in language model pre-training has achieved a great success via leveraging large-scale unstructured textual data. However, it is
+still a challenge to apply pre-training on structured tabular data due to the absence of large-scale high-quality tabular data. In this paper, we
+propose TAPEX to show that table pre-training can be achieved by learning a neural SQL executor over a synthetic corpus, which is obtained by automatically
+synthesizing executable SQL queries and their execution outputs. TAPEX addresses the data scarcity challenge via guiding the language model to mimic a SQL
+executor on the diverse, large-scale and high-quality synthetic corpus. We evaluate TAPEX on four benchmark datasets. Experimental results demonstrate that
+TAPEX outperforms previous table pre-training approaches by a large margin and achieves new state-of-the-art results on all of them. This includes improvements
+on the weakly-supervised WikiSQL denotation accuracy to 89.5% (+2.3%), the WikiTableQuestions denotation accuracy to 57.5% (+4.8%), the SQA denotation accuracy
+to 74.5% (+3.5%), and the TabFact accuracy to 84.2% (+3.2%). To our knowledge, this is the first work to exploit table pre-training via synthetic executable programs
+and to achieve new state-of-the-art results on various downstream tasks.*
+
+Tips:
+
+- TAPEX is a generative (seq2seq) model. One can directly plug in the weights of TAPEX into a BART model. 
+- TAPEX has checkpoints on the hub that are either pre-trained only, or fine-tuned on WTQ, SQA, WikiSQL and TabFact.
+- Sentences + tables are presented to the model as `sentence + " " + linearized table`. The linearized table has the following format: 
+  `col: col1 | col2 | col 3 row 1 : val1 | val2 | val3 row 2 : ...`.
+- TAPEX has its own tokenizer, that allows to prepare all data for the model easily. One can pass Pandas DataFrames and strings to the tokenizer,
+  and it will automatically create the `input_ids` and `attention_mask` (as shown in the usage examples below). 
+
+## Usage: inference
+
+Below, we illustrate how to use TAPEX for table question answering. As one can see, one can directly plug in the weights of TAPEX into a BART model.
+We use the [Auto API](auto), which will automatically instantiate the appropriate tokenizer ([`TapexTokenizer`]) and model ([`BartForConditionalGeneration`]) for us,
+based on the configuration file of the checkpoint on the hub.
+
+```python
+>>> from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
+>>> import pandas as pd
+
+>>> tokenizer = AutoTokenizer.from_pretrained("microsoft/tapex-large-finetuned-wtq")
+>>> model = AutoModelForSeq2SeqLM.from_pretrained("microsoft/tapex-large-finetuned-wtq")
+
+>>> # prepare table + question
+>>> data = {"Actors": ["Brad Pitt", "Leonardo Di Caprio", "George Clooney"], "Number of movies": ["87", "53", "69"]}
+>>> table = pd.DataFrame.from_dict(data)
+>>> question = "how many movies does Leonardo Di Caprio have?"
+
+>>> encoding = tokenizer(table, question, return_tensors="pt")
+
+>>> # let the model generate an answer autoregressively
+>>> outputs = model.generate(**encoding)
+
+>>> # decode back to text
+>>> predicted_answer = tokenizer.batch_decode(outputs, skip_special_tokens=True)[0]
+>>> print(predicted_answer)
+53
+```
+
+Note that [`TapexTokenizer`] also supports batched inference. Hence, one can provide a batch of different tables/questions, or a batch of a single table
+and multiple questions, or a batch of a single query and multiple tables. Let's illustrate this:
+
+```python
+>>> # prepare table + question
+>>> data = {"Actors": ["Brad Pitt", "Leonardo Di Caprio", "George Clooney"], "Number of movies": ["87", "53", "69"]}
+>>> table = pd.DataFrame.from_dict(data)
+>>> questions = [
+...     "how many movies does Leonardo Di Caprio have?",
+...     "which actor has 69 movies?",
+...     "what's the first name of the actor who has 87 movies?",
+... ]
+>>> encoding = tokenizer(table, questions, padding=True, return_tensors="pt")
+
+>>> # let the model generate an answer autoregressively
+>>> outputs = model.generate(**encoding)
+
+>>> # decode back to text
+>>> tokenizer.batch_decode(outputs, skip_special_tokens=True)
+[' 53', ' george clooney', ' brad pitt']
+```
+
+In case one wants to do table verification (i.e. the task of determining whether a given sentence is supported or refuted by the contents
+of a table), one can instantiate a [`BartForSequenceClassification`] model. TAPEX has checkpoints on the hub fine-tuned on TabFact, an important
+benchmark for table fact checking (it achieves 84% accuracy). The code example below again leverages the [Auto API](auto).
+
+```python
+>>> from transformers import AutoTokenizer, AutoModelForSequenceClassification
+
+>>> tokenizer = AutoTokenizer.from_pretrained("microsoft/tapex-large-finetuned-tabfact")
+>>> model = AutoModelForSequenceClassification.from_pretrained("microsoft/tapex-large-finetuned-tabfact")
+
+>>> # prepare table + sentence
+>>> data = {"Actors": ["Brad Pitt", "Leonardo Di Caprio", "George Clooney"], "Number of movies": ["87", "53", "69"]}
+>>> table = pd.DataFrame.from_dict(data)
+>>> sentence = "George Clooney has 30 movies"
+
+>>> encoding = tokenizer(table, sentence, return_tensors="pt")
+
+>>> # forward pass
+>>> outputs = model(**encoding)
+
+>>> # print prediction
+>>> predicted_class_idx = outputs.logits[0].argmax(dim=0).item()
+>>> print(model.config.id2label[predicted_class_idx])
+Refused
+```

+# YOLOS
+
+## Overview
+
+The YOLOS model was proposed in [You Only Look at One Sequence: Rethinking Transformer in Vision through Object Detection](https://arxiv.org/abs/2106.00666) by Yuxin Fang, Bencheng Liao, Xinggang Wang, Jiemin Fang, Jiyang Qi, Rui Wu, Jianwei Niu, Wenyu Liu.
+YOLOS proposes to just leverage the plain [Vision Transformer (ViT)](vit) for object detection, inspired by DETR. It turns out that a base-sized encoder-only Transformer can also achieve 42 AP on COCO, similar to DETR and much more complex frameworks such as Faster R-CNN.
+
+The abstract from the paper is the following:
+
+*Can Transformer perform 2D object- and region-level recognition from a pure sequence-to-sequence perspective with minimal knowledge about the 2D spatial structure? To answer this question, we present You Only Look at One Sequence (YOLOS), a series of object detection models based on the vanilla Vision Transformer with the fewest possible modifications, region priors, as well as inductive biases of the target task. We find that YOLOS pre-trained on the mid-sized ImageNet-1k dataset only can already achieve quite competitive performance on the challenging COCO object detection benchmark, e.g., YOLOS-Base directly adopted from BERT-Base architecture can obtain 42.0 box AP on COCO val. We also discuss the impacts as well as limitations of current pre-train schemes and model scaling strategies for Transformer in vision through YOLOS.*
+
+Tips:
+
+- One can use [`YolosFeatureExtractor`] for preparing images (and optional targets) for the model. Contrary to [DETR](detr), YOLOS doesn't require a `pixel_mask` to be created.
+- Demo notebooks (regarding inference and fine-tuning on custom data) can be found [here](https://github.com/NielsRogge/Transformers-Tutorials/tree/master/YOLOS).

 Audio classification assigns a label or class to audio data. It is similar to text classification, except an audio input is continuous and must be discretized, whereas text can be split into tokens. Some practical applications of audio classification include identifying intent, speakers, and even animal species by their sounds.

+# Carga instancias preentrenadas con un AutoClass
+
+Con tantas arquitecturas diferentes de Transformer puede ser retador crear una para tu checkpoint. Como parte de la filosofía central de 🤗 Transformers para hacer que la biblioteca sea fácil, simple y flexible de usar; una `AutoClass` automáticamente infiere y carga la arquitectura correcta desde un checkpoint dado. El método `from_pretrained` te permite cargar rápidamente un modelo preentrenado para cualquier arquitectura, por lo que no tendrás que dedicar tiempo y recursos para entrenar uno desde cero. Producir este tipo de código con checkpoint implica que si funciona con uno, funcionará también con otro (siempre que haya sido entrenado para una tarea similar) incluso si la arquitectura es distinta.
+
+<Tip>
+
+Recuerda, la arquitectura se refiere al esqueleto del modelo y los checkpoints son los pesos para una arquitectura dada. Por ejemplo, [BERT](https://huggingface.co/bert-base-uncased) es una arquitectura, mientras que `bert-base-uncased` es un checkpoint. Modelo es un término general que puede significar una arquitectura o un checkpoint.
+
+</Tip>
+
+En este tutorial, aprende a:
+
+* Cargar un tokenizador preentrenado.
+* Cargar un extractor de características (feature extractor) preentrenado.
+* Cargar un procesador preentrenado.
+* Cargar un modelo preentrenado.
+
+## AutoTokenizer
+
+Casi cualquier tarea de Natural Language Processing comienza con un tokenizador. Un tokenizador convierte tu input a un formato que puede ser procesado por el modelo.
+
+Carga un tokenizador con [`AutoTokenizer.from_pretrained`]:
+
+```py
+>>> from transformers import AutoTokenizer
+
+>>> tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
+```
+
+Luego tokeniza tu input como lo mostrado a continuación:
+
+```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
+
+Para tareas de audio y visión, un extractor de características procesa la señal de audio o imagen al formato de input correcto.
+
+Carga un extractor de características con [`AutoFeatureExtractor.from_pretrained`]:
+
+```py
+>>> from transformers import AutoFeatureExtractor
+
+>>> feature_extractor = AutoFeatureExtractor.from_pretrained(
+...     "ehcalabres/wav2vec2-lg-xlsr-en-speech-emotion-recognition"
+... )
+```
+
+## AutoProcessor
+
+Las tareas multimodales requieren un procesador que combine dos tipos de herramientas de preprocesamiento. Por ejemplo, el modelo [LayoutLMV2](model_doc/layoutlmv2) requiere que un extractor de características maneje las imágenes y que un tokenizador maneje el texto; un procesador combina ambas.
+
+Carga un procesador con [`AutoProcessor.from_pretrained`]:
+
+```py
+>>> from transformers import AutoProcessor
+
+>>> processor = AutoProcessor.from_pretrained("microsoft/layoutlmv2-base-uncased")
+```
+
+## AutoModel
+
+<frameworkcontent>
+<pt>
+Finalmente, las clases `AutoModelFor` te permiten cargar un modelo preentrenado para una tarea dada (revisa [aquí](model_doc/auto) para conocer la lista completa de tareas disponibles). Por ejemplo, cargue un modelo para clasificación de secuencias con [`AutoModelForSequenceClassification.from_pretrained`]:
+
+```py
+>>> from transformers import AutoModelForSequenceClassification
+
+>>> model = AutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased")
+```
+
+Reutilice fácilmente el mismo checkpoint para cargar una aquitectura para alguna tarea diferente:
+
+```py
+>>> from transformers import AutoModelForTokenClassification
+
+>>> model = AutoModelForTokenClassification.from_pretrained("distilbert-base-uncased")
+```
+
+Generalmente recomendamos utilizar las clases `AutoTokenizer` y `AutoModelFor` para cargar instancias preentrenadas de modelos. Ésto asegurará que cargues la arquitectura correcta en cada ocasión. En el siguiente [tutorial](preprocessing), aprende a usar tu tokenizador recién cargado, el extractor de características y el procesador para preprocesar un dataset para fine-tuning.
+</pt>
+<tf>
+Finalmente, la clase `TFAutoModelFor` te permite cargar tu modelo preentrenado para una tarea dada (revisa [aquí](model_doc/auto) para conocer la lista completa de tareas disponibles). Por ejemplo, carga un modelo para clasificación de secuencias con [`TFAutoModelForSequenceClassification.from_pretrained`]:
+
+```py
+>>> from transformers import TFAutoModelForSequenceClassification
+
+>>> model = TFAutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased")
+```
+
+Reutilice fácilmente el mismo checkpoint para cargar una aquitectura para alguna tarea diferente:
+
+```py
+>>> from transformers import TFAutoModelForTokenClassification
+
+>>> model = TFAutoModelForTokenClassification.from_pretrained("distilbert-base-uncased")
+```
+
+Generalmente recomendamos utilizar las clases `AutoTokenizer` y `TFAutoModelFor` para cargar instancias de modelos preentrenados. Ésto asegurará que cargues la arquitectura correcta cada vez. En el siguiente [tutorial](preprocessing), aprende a usar tu tokenizador recién cargado, el extractor de características y el procesador para preprocesar un dataset para fine-tuning.

+# Usa los tokenizadores de 🤗 Tokenizers
+
+[`PreTrainedTokenizerFast`] depende de la biblioteca [🤗 Tokenizers](https://huggingface.co/docs/tokenizers). Los tokenizadores obtenidos desde la biblioteca 🤗 Tokenizers pueden ser 
+cargados de forma muy sencilla en los 🤗 Transformers.
+
+Antes de entrar en detalles, comencemos creando un tokenizador dummy en unas cuantas líneas:
+
+```python
+>>> from tokenizers import Tokenizer
+>>> from tokenizers.models import BPE
+>>> from tokenizers.trainers import BpeTrainer
+>>> from tokenizers.pre_tokenizers import Whitespace
+
+>>> tokenizer = Tokenizer(BPE(unk_token="[UNK]"))
+>>> trainer = BpeTrainer(special_tokens=["[UNK]", "[CLS]", "[SEP]", "[PAD]", "[MASK]"])
+
+>>> tokenizer.pre_tokenizer = Whitespace()
+>>> files = [...]
+>>> tokenizer.train(files, trainer)
+```
+
+Ahora tenemos un tokenizador entrenado en los archivos que definimos. Lo podemos seguir utilizando en ese entorno de ejecución (runtime en inglés), o puedes guardarlo
+en un archivo JSON para reutilizarlo en un futuro.
+
+## Cargando directamente desde el objeto tokenizador 
+
+Veamos cómo utilizar este objeto tokenizador en la biblioteca 🤗 Transformers. La clase
+[`PreTrainedTokenizerFast`] permite una instanciación fácil, al aceptar el objeto
+*tokenizer* instanciado como argumento:
+
+```python
+>>> from transformers import PreTrainedTokenizerFast
+
+>>> fast_tokenizer = PreTrainedTokenizerFast(tokenizer_object=tokenizer)
+```
+
+Este objeto ya puede ser utilizado con todos los métodos compartidos por los tokenizadores de 🤗 Transformers! Visita la [página sobre tokenizadores
+](main_classes/tokenizer) para más información.
+
+## Cargando desde un archivo JSON
+
+Para cargar un tokenizador desde un archivo JSON, comencemos por guardar nuestro tokenizador:
+
+```python
+>>> tokenizer.save("tokenizer.json")
+```
+
+La localización (path en inglés) donde este archivo es guardado puede ser incluida en el método de inicialización de [`PreTrainedTokenizerFast`]
+utilizando el parámetro `tokenizer_file`:
+
+```python
+>>> from transformers import PreTrainedTokenizerFast
+
+>>> fast_tokenizer = PreTrainedTokenizerFast(tokenizer_file="tokenizer.json")
+```
+
+Este objeto ya puede ser utilizado con todos los métodos compartidos por los tokenizadores de 🤗 Transformers! Visita la [página sobre tokenizadores
+](main_classes/tokenizer) para más información.

+# Modelado de lenguaje
+
+El modelado de lenguaje predice palabras en un enunciado. Hay dos formas de modelado de lenguaje.
+
+<Youtube id="Vpjb1lu0MDk"/>
+
+El modelado de lenguaje causal predice el siguiente token en una secuencia de tokens, y el modelo solo puede considerar los tokens a la izquierda.
+
+<Youtube id="mqElG5QJWUg"/>
+
+El modelado de lenguaje por enmascaramiento predice un token enmascarado en una secuencia, y el modelo puede considerar los tokens bidireccionalmente.
+
+Esta guía te mostrará cómo realizar fine-tuning [DistilGPT2](https://huggingface.co/distilgpt2) para modelos de lenguaje causales y [DistilRoBERTa](https://huggingface.co/distilroberta-base) para modelos de lenguaje por enmascaramiento en el [r/askscience](https://www.reddit.com/r/askscience/) subdataset [ELI5](https://huggingface.co/datasets/eli5). 
+
+<Tip>
+
+Puedes realizar fine-tuning a otras arquitecturas para modelos de lenguaje como [GPT-Neo](https://huggingface.co/EleutherAI/gpt-neo-125M), [GPT-J](https://huggingface.co/EleutherAI/gpt-j-6B) y [BERT](https://huggingface.co/bert-base-uncased) siguiendo los mismos pasos presentados en esta guía!
+
+Mira la [página de tarea](https://huggingface.co/tasks/text-generation) para generación de texto y la [página de tarea](https://huggingface.co/tasks/fill-mask) para modelos de lenguajes por enmascaramiento para obtener más información sobre los modelos, datasets, y métricas asociadas.
+
+</Tip>
+
+## Carga el dataset ELI5
+
+Carga solo los primeros 5000 registros desde la biblioteca 🤗 Datasets, dado que es bastante grande:
+
+```py
+>>> from datasets import load_dataset
+
+>>> eli5 = load_dataset("eli5", split="train_asks[:5000]")
+```
+
+Divide este dataset en subdatasets para el entrenamiento y el test:
+
+```py
+eli5 = eli5.train_test_split(test_size=0.2)
+```
+
+Luego observa un ejemplo:
+
+```py
+>>> eli5["train"][0]
+{'answers': {'a_id': ['c3d1aib', 'c3d4lya'],
+  'score': [6, 3],
+  'text': ["The velocity needed to remain in orbit is equal to the square root of Newton's constant times the mass of earth divided by the distance from the center of the earth. I don't know the altitude of that specific mission, but they're usually around 300 km. That means he's going 7-8 km/s.\n\nIn space there are no other forces acting on either the shuttle or the guy, so they stay in the same position relative to each other. If he were to become unable to return to the ship, he would presumably run out of oxygen, or slowly fall into the atmosphere and burn up.",
+   "Hope you don't mind me asking another question, but why aren't there any stars visible in this photo?"]},
+ 'answers_urls': {'url': []},
+ 'document': '',
+ 'q_id': 'nyxfp',
+ 'selftext': '_URL_0_\n\nThis was on the front page earlier and I have a few questions about it. Is it possible to calculate how fast the astronaut would be orbiting the earth? Also how does he stay close to the shuttle so that he can return safely, i.e is he orbiting at the same speed and can therefore stay next to it? And finally if his propulsion system failed, would he eventually re-enter the atmosphere and presumably die?',
+ 'selftext_urls': {'url': ['http://apod.nasa.gov/apod/image/1201/freeflyer_nasa_3000.jpg']},
+ 'subreddit': 'askscience',
+ 'title': 'Few questions about this space walk photograph.',
+ 'title_urls': {'url': []}}
+```
+
+Observa que `text` es un subcampo anidado dentro del diccionario `answers`. Cuando preproceses el dataset, deberás extraer el subcampo `text` en una columna aparte.
+
+## Preprocesamiento
+
+<Youtube id="ma1TrR7gE7I"/>
+
+Para modelados de lenguaje causales carga el tokenizador DistilGPT2 para procesar el subcampo `text`:
+
+```py
+>>> from transformers import AutoTokenizer
+
+>>> tokenizer = AutoTokenizer.from_pretrained("distilgpt2")
+```
+
+<Youtube id="8PmhEIXhBvI"/>
+
+Para modelados de lenguaje por enmascaramiento carga el tokenizador DistilRoBERTa, en lugar de DistilGPT2:
+
+```py
+>>> from transformers import AutoTokenizer
+
+>>> tokenizer = AutoTokenizer.from_pretrained("distilroberta-base")
+```
+
+Extrae el subcampo `text` desde su estructura anidado con el método [`flatten`](https://huggingface.co/docs/datasets/process.html#flatten):
+
+```py
+>>> eli5 = eli5.flatten()
+>>> eli5["train"][0]
+{'answers.a_id': ['c3d1aib', 'c3d4lya'],
+ 'answers.score': [6, 3],
+ 'answers.text': ["The velocity needed to remain in orbit is equal to the square root of Newton's constant times the mass of earth divided by the distance from the center of the earth. I don't know the altitude of that specific mission, but they're usually around 300 km. That means he's going 7-8 km/s.\n\nIn space there are no other forces acting on either the shuttle or the guy, so they stay in the same position relative to each other. If he were to become unable to return to the ship, he would presumably run out of oxygen, or slowly fall into the atmosphere and burn up.",
+  "Hope you don't mind me asking another question, but why aren't there any stars visible in this photo?"],
+ 'answers_urls.url': [],
+ 'document': '',
+ 'q_id': 'nyxfp',
+ 'selftext': '_URL_0_\n\nThis was on the front page earlier and I have a few questions about it. Is it possible to calculate how fast the astronaut would be orbiting the earth? Also how does he stay close to the shuttle so that he can return safely, i.e is he orbiting at the same speed and can therefore stay next to it? And finally if his propulsion system failed, would he eventually re-enter the atmosphere and presumably die?',
+ 'selftext_urls.url': ['http://apod.nasa.gov/apod/image/1201/freeflyer_nasa_3000.jpg'],
+ 'subreddit': 'askscience',
+ 'title': 'Few questions about this space walk photograph.',
+ 'title_urls.url': []}
+```
+
+Cada subcampo es ahora una columna separada, como lo indica el prefijo `answers`. Observa que `answers.text` es una lista. En lugar de tokenizar cada enunciado por separado, convierte la lista en un string para tokenizarlos conjuntamente.
+
+Así es como puedes crear una función de preprocesamiento para convertir la lista en una cadena y truncar las secuencias para que no superen la longitud máxima de input de DistilGPT2:
+
+```py
+>>> def preprocess_function(examples):
+...     return tokenizer([" ".join(x) for x in examples["answers.text"]], truncation=True)
+```
+
+Usa de 🤗 Datasets la función [`map`](https://huggingface.co/docs/datasets/package_reference/main_classes.html#datasets.Dataset.map) para aplicar la función de preprocesamiento sobre el dataset en su totalidad. Puedes acelerar la función `map` configurando el argumento `batched=True` para procesar múltiples elementos del dataset a la vez y aumentar la cantidad de procesos con `num_proc`. Elimina las columnas que no necesitas:
+
+```py
+>>> tokenized_eli5 = eli5.map(
+...     preprocess_function,
+...     batched=True,
+...     num_proc=4,
+...     remove_columns=eli5["train"].column_names,
+... )
+```
+
+Ahora necesitas una segunda función de preprocesamiento para capturar el texto truncado de cualquier ejemplo demasiado largo para evitar cualquier pérdida de información. Esta función de preprocesamiento debería:
+
+- Concatenar todo el texto.
+- Dividir el texto concatenado en trozos más pequeños definidos por un `block_size`.
+
+```py
+>>> block_size = 128
+
+
+>>> def group_texts(examples):
+...     concatenated_examples = {k: sum(examples[k], []) for k in examples.keys()}
+...     total_length = len(concatenated_examples[list(examples.keys())[0]])
+...     result = {
+...         k: [t[i : i + block_size] for i in range(0, total_length, block_size)]
+...         for k, t in concatenated_examples.items()
+...     }
+...     result["labels"] = result["input_ids"].copy()
+...     return result
+```
+
+Aplica la función `group_texts` sobre todo el dataset:
+
+```py
+>>> lm_dataset = tokenized_eli5.map(group_texts, batched=True, num_proc=4)
+```
+
+Para modelados de lenguaje causales, usa [`DataCollatorForLanguageModeling`] para crear un lote de ejemplos. Esto también *rellenará dinámicamente* tu texto a la dimensión del elemento más largo del lote para que de esta manera tengan largo uniforme. Si bien es posible rellenar tu texto en la función `tokenizer` mediante el argumento `padding=True`, el rellenado dinámico es más eficiente. 
+
+<frameworkcontent>
+<pt>
+Puedes usar el token de final de secuencia como el token de relleno y asignar `mlm=False`. Esto usará los inputs como etiquetas movidas un elemento hacia la derecha:
+
+```py
+>>> from transformers import DataCollatorForLanguageModeling
+
+>>> tokenizer.pad_token = tokenizer.eos_token
+>>> data_collator = DataCollatorForLanguageModeling(tokenizer=tokenizer, mlm=False)
+```
+
+Para modelados de lenguaje por enmascaramiento usa el mismo [`DataCollatorForLanguageModeling`] excepto que deberás especificar `mlm_probability` para enmascarar tokens aleatoriamente cada vez que iteras sobre los datos.
+
+```py
+>>> from transformers import DataCollatorForLanguageModeling
+
+>>> tokenizer.pad_token = tokenizer.eos_token
+>>> data_collator = DataCollatorForLanguageModeling(tokenizer=tokenizer, mlm_probability=0.15)
+```
+</pt>
+<tf>
+Puedes usar el token de final de secuencia como el token de relleno y asignar `mlm=False`. Esto usará los inputs como etiquetas movidas un elemento hacia la derecha:
+
+```py
+>>> from transformers import DataCollatorForLanguageModeling
+
+>>> data_collator = DataCollatorForLanguageModeling(tokenizer=tokenizer, mlm=False, return_tensors="tf")
+```
+
+Para modelados de lenguajes por enmascaramiento usa el mismo [`DataCollatorForLanguageModeling`] excepto que deberás especificar `mlm_probability` para enmascarar tokens aleatoriamente cada vez que iteras sobre los datos.
+

+>>> from transformers import DataCollatorForLanguageModeling
+
+>>> data_collator = DataCollatorForLanguageModeling(tokenizer=tokenizer, mlm=False, return_tensors="tf")
+```

+
+## Modelado de lenguaje causal
+
+El modelado de lenguaje causal es frecuentemente utilizado para generación de texto. Esta sección te muestra cómo realizar fine-tuning a [DistilGPT2](https://huggingface.co/distilgpt2) para generar nuevo texto.
+
+### Entrenamiento
+
+<frameworkcontent>
+<pt>
+Carga DistilGPT2 con [`AutoModelForCausalLM`]:
+
+```py
+>>> from transformers import AutoModelForCausalLM, TrainingArguments, Trainer
+
+>>> model = AutoModelForCausalLM.from_pretrained("distilgpt2")
+```
+
+<Tip>
+
+Si no estás familiarizado con el proceso de realizar fine-tuning sobre un modelo con [`Trainer`], considera el tutorial básico [aquí](../training#finetune-with-trainer)!
+
+</Tip>
+
+A este punto, solo faltan tres pasos:
+
+1. Definir tus hiperparámetros de entrenamiento en [`TrainingArguments`].
+2. Pasarle los argumentos de entrenamiento a [`Trainer`] junto con el modelo, dataset, y el data collator.
+3. Realiza la llamada [`~Trainer.train`] para realizar el fine-tuning sobre tu modelo.
+
+```py
+>>> training_args = TrainingArguments(
+...     output_dir="./results",
+...     evaluation_strategy="epoch",
+...     learning_rate=2e-5,
+...     weight_decay=0.01,
+... )
+
+>>> trainer = Trainer(
+...     model=model,
+...     args=training_args,
+...     train_dataset=lm_dataset["train"],
+...     eval_dataset=lm_dataset["test"],
+...     data_collator=data_collator,
+... )
+
+>>> trainer.train()
+```
+</pt>
+<tf>
+Para realizar el fine-tuning de un modelo en TensorFlow, comienza por convertir tus datasets al formato `tf.data.Dataset` con [`to_tf_dataset`](https://huggingface.co/docs/datasets/package_reference/main_classes.html#datasets.Dataset.to_tf_dataset). Especifica los inputs y etiquetas en `columns`, ya sea para mezclar el dataset, tamaño de lote, y el data collator:
+
+```py
+>>> tf_train_set = lm_dataset["train"].to_tf_dataset(
+...     columns=["attention_mask", "input_ids", "labels"],
+...     dummy_labels=True,
+...     shuffle=True,
+...     batch_size=16,
+...     collate_fn=data_collator,
+... )
+
+>>> tf_test_set = lm_dataset["test"].to_tf_dataset(
+...     columns=["attention_mask", "input_ids", "labels"],
+...     dummy_labels=True,
+...     shuffle=False,
+...     batch_size=16,
+...     collate_fn=data_collator,
+... )
+```
+
+<Tip>
+
+Si no estás familiarizado con realizar fine-tuning de tus modelos con Keras, considera el tutorial básico [aquí](training#finetune-with-keras)!
+
+</Tip>
+
+Crea la función optimizadora, la tasa de aprendizaje, y algunos hiperparámetros de entrenamiento:
+
+```py
+>>> from transformers import create_optimizer, AdamWeightDecay
+
+>>> optimizer = AdamWeightDecay(learning_rate=2e-5, weight_decay_rate=0.01)
+```
+
+Carga DistilGPT2 con [`TFAutoModelForCausalLM`]:
+
+```py
+>>> from transformers import TFAutoModelForCausalLM
+
+>>> model = TFAutoModelForCausalLM.from_pretrained("distilgpt2")
+```
+
+Configura el modelo para entrenamiento con [`compile`](https://keras.io/api/models/model_training_apis/#compile-method):
+
+```py
+>>> import tensorflow as tf
+
+>>> model.compile(optimizer=optimizer)
+```
+
+Llama a [`fit`](https://keras.io/api/models/model_training_apis/#fit-method) para realizar el fine-tuning del modelo:
+
+```py
+>>> model.fit(x=tf_train_set, validation_data=tf_test_set, epochs=3)
+```
+</tf>
+</frameworkcontent>
+
+## Modelado de lenguaje por enmascaramiento
+
+El modelado de lenguaje por enmascaramiento es también conocido como una tarea de rellenar la máscara, pues predice un token enmascarado dada una secuencia. Los modelos de lenguaje por enmascaramiento requieren una buena comprensión del contexto de una secuencia entera, en lugar de solo el contexto a la izquierda. Esta sección te enseña como realizar el fine-tuning de [DistilRoBERTa](https://huggingface.co/distilroberta-base) para predecir una palabra enmascarada.

+
+# Filosofía
+
+🤗 Transformers es una biblioteca construida para:
+
+- Los investigadores y educadores de NLP que busquen usar/estudiar/extender modelos transformers a gran escala 
+- Profesionales que quieren optimizar esos modelos y/o ponerlos en producción 
+- Ingenieros que solo quieren descargar un modelo preentrenado y usarlo para resolver una tarea NLP dada. 
+
+La biblioteca fue diseñada con dos fuertes objetivos en mente:
+
+- Que sea tan fácil y rápida de utilizar como sea posible:
+
+  - Hemos limitado enormemente el número de abstracciones que el usuario tiene que aprender. De hecho, no hay casi abstracciones,
+    solo tres clases estándar necesarias para usar cada modelo: [configuration](main_classes/configuration),
+    [models](main_classes/model) y [tokenizer](main_classes/tokenizer).
+  - Todas estas clases pueden ser inicializadas de forma simple y unificada a partir de ejemplos pre-entrenados mediante el uso de un método
+    `from_pretrained()` común de solicitud que se encargará de descargar (si es necesario), almacenar y cargar la solicitud de clase relacionada y datos asociados
+    (configurations' hyper-parameters, tokenizers' vocabulary, and models' weights) a partir de un control pre-entrenado proporcionado en
+    [Hugging Face Hub](https://huggingface.co/models) o de tu propio control guardado.
+  - Por encima de esas tres clases estándar, la biblioteca proporciona dos APIs: [`pipeline`] para usar rápidamente un modelo (junto a su configuracion y tokenizer asociados)
+    sobre una tarea dada, y [`Trainer`]/`Keras.fit` para entrenar u optimizar de forma rápida un modelo dado.
+  - Como consecuencia, esta biblioteca NO es una caja de herramientas modular de bloques individuales para redes neuronales. Si quieres extender/construir sobre la biblioteca,
+    usa simplemente los módulos regulares de Python/PyTorch/TensorFlow/Keras y emplea las clases estándar de la biblioteca como punto de partida para reutilizar funcionalidades
+    tales como abrir/guardar modelo.
+    
+- Proporciona modelos modernos con rendimientos lo más parecido posible a los modelos originales:
+
+  - Proporcionamos al menos un ejemplo para cada arquitectura que reproduce un resultado proporcionado por los autores de dicha arquitectura.
+  - El código normalmente es parecido al código base original, lo cual significa que algún código Pytorch puede no ser tan 
+    *pytorchic* como podría ser por haber sido convertido a código TensorFlow, y viceversa. 
+
+Unos cuantos objetivos adicionales:
+
+- Exponer las características internas de los modelos de la forma más coherente posible:
+
+  - Damos acceso, mediante una sola API, a todos los estados ocultos y pesos de atención.
+  - Tokenizer y el modelo de API base están estandarizados para cambiar fácilmente entre modelos.
+
+- Incorporar una selección subjetiva de herramientas de gran potencial para la optimización/investigación de estos modelos:
+
+  - Una forma sencilla/coherente de añadir nuevos tokens al vocabulario e incrustraciones (embeddings, en inglés) para optimización.
+  - Formas sencillas de camuflar y reducir "transformer heads".
+
+- Cambiar fácilmente entre PyTorch y TensorFlow 2.0, permitiendo el entrenamiento usando un marco y la inferencia usando otro.
+
+## Conceptos principales 
+
+La biblioteca está construida alrededor de tres tipos de clases para cada modelo:
+
+- **Model classes** como [`BertModel`], que consisten en más de 30 modelos PyTorch ([torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module)) o modelos Keras ([tf.keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model)) que funcionan con pesos pre-entrenados proporcionados en la
+  biblioteca.
+- **Configuration classes** como [`BertConfig`], que almacena todos los parámetros necesarios para construir un modelo. 
+  No siempre tienes que generarla tu. En particular, si estas usando un modelo pre-entrenado sin ninguna modificación,
+  la creación del modelo se encargará automáticamente de generar la configuración (que es parte del modelo).
+- **Tokenizer classes** como [`BertTokenizer`], que almacena el vocabulario para cada modelo y proporciona métodos para
+  codificar/decodificar strings en una lista de índices de "token embeddings" para ser empleados en un modelo.          
+
+Todas estas clases pueden ser generadas a partir de ejemplos pre-entrenados, y guardados localmente usando dos métodos:
+
+- `from_pretrained()` permite generar un modelo/configuración/tokenizer a partir de una versión pre-entrenada proporcionada ya sea por
+  la propia biblioteca (los modelos compatibles se pueden encontrar en [Model Hub](https://huggingface.co/models)) o
+  guardados localmente (o en un servidor) por el usuario. 
+- `save_pretrained()` permite guardar un modelo/configuración/tokenizer localmente, de forma que puede ser empleado de nuevo usando
+  `from_pretrained()`.

-* Análisis de Sentimientos: clasifica la polaridad de un texto dado.
-* Generación de texto (solo en inglés): genera texto a partir de un input dado.
-* Name entity recognition (NER): etiqueta cada palabra con la entidad que representa (persona, fecha, ubicación, etc.).
-* Responder preguntas: extrae la respuesta del contexto dado un contexto y una pregunta.
-* Fill-mask: rellena el espacio faltante dado un texto con palabras enmascaradas.
-* Summarization: genera un resumen de una secuencia larga de texto o un documento.
-* Traducción: traduce un texto a otro idioma.
-* Extracción de características: crea una representación tensorial del texto.

+#### Upload your data to the hub, as a (possibly private) repo
 
-## Sharing your model on 🤗 Hub
+It's very easy (and convenient) to upload your image dataset to the hub using the [`ImageFolder`](https://huggingface.co/docs/datasets/v2.0.0/en/image_process#imagefolder) feature available in 🤗 Datasets. Simply do the following:
+
+```python
+from datasets import load_dataset
+
+# example 1: local folder
+dataset = load_dataset("imagefolder", data_dir="path_to_your_folder")
+
+# example 2: local files (suppoted formats are tar, gzip, zip, xz, rar, zstd)
+dataset = load_dataset("imagefolder", data_files="path_to_zip_file")
+
+# example 3: remote files (suppoted formats are tar, gzip, zip, xz, rar, zstd)
+dataset = load_dataset("imagefolder", data_files="https://download.microsoft.com/download/3/E/1/3E1C3F21-ECDB-4869-8368-6DEBA77B919F/kagglecatsanddogs_3367a.zip")
+
+# example 4: providing several splits
+dataset = load_dataset("imagefolder", data_files={"train": ["path/to/file1", "path/to/file2"], "test": ["path/to/file3", "path/to/file4"]})
+```
+
+`ImageFolder` will create a `label` column, and the label name is based on the directory name.
+
+Next, push it to the hub!
+
+```python
+# assuming you have ran the huggingface-cli login command in a terminal
+dataset.push_to_hub("name_of_your_dataset")
+
+# if you want to push to a private repo, simply pass private=True:
+dataset.push_to_hub("name_of_your_dataset", private=True)
+```
+
+and that's it! You can now train your model by simply setting the `--dataset_name` argument to the name of your dataset on the hub (as explained in [Using datasets from the 🤗 hub](#using-datasets-from-hub)).
+

+## PyTorch version, no Trainer
+
+Based on the script [`run_image_classification_no_trainer.py`](https://github.com/huggingface/transformers/blob/main/examples/pytorch/image-classification/run_image_classification_no_trainer.py).
+
+Like `run_image_classification.py`, this script allows you to fine-tune any of the models on the [hub](https://huggingface.co/models) on an image classification task. The main difference is that this script exposes the bare training loop, to allow you to quickly experiment and add any customization you would like.
+
+It offers less options than the script with `Trainer` (for instance you can easily change the options for the optimizer
+or the dataloaders directly in the script) but still run in a distributed setup, and supports mixed precision by
+the means of the [🤗 `Accelerate`](https://github.com/huggingface/accelerate) library. You can use the script normally
+after installing it:
+
+```bash
+pip install git+https://github.com/huggingface/accelerate
+```
+
+You can then use your usual launchers to run in it in a distributed environment, but the easiest way is to run
+
+```bash
+accelerate config
+```
+
+and reply to the questions asked. Then
+
+```bash
+accelerate test
+```
+
+that will check everything is ready for training. Finally, you can launch training with
+
+```bash
+accelerate launch run_image_classification_trainer.py
+```
+
+This command is the same and will work for:
+
+- single/multiple CPUs
+- single/multiple GPUs
+- TPUs
+
+Note that this library is in alpha release so your feedback is more than welcome if you encounter any problem using it.
+
+Regarding using custom data with this script, we refer to [using your own data](#using-your-own-data).
