# Mistral
|
||||
|
||||
## Overview
|
||||
|
||||
Mistral-7B-v0.1 is Mistral AI’s first Large Language Model (LLM).
|
||||
|
||||
## Model Details
|
||||
|
||||
Mistral-7B-v0.1 is a decoder-based LM with the following architectural choices:
|
||||
* Sliding Window Attention - Trained with 8k context length and fixed cache size, with a theoretical attention span of 128K tokens
|
||||
* GQA (Grouped Query Attention) - allowing faster inference and lower cache size.
|
||||
* Byte-fallback BPE tokenizer - ensures that characters are never mapped to out of vocabulary tokens.
|
||||
|
||||
We also provide an instruction fine-tuned model: `Mistral-7B-Instruct-v0.1` which can be used for chat-based inference.
|
||||
|
||||
For more details please read our [release blog post](https://mistral.ai/news/announcing-mistral-7b-v0.1/)
|
||||
|
||||
## License
|
||||
|
||||
Both `Mistral-7B-v0.1` and `Mistral-7B-Instruct-v0.1` are released under the Apache 2.0 license.
|
||||
|

`Mistral-7B-v0.1` and `Mistral-7B-Instruct-v0.1` can be found on the [Huggingface Hub](https://huggingface.co/mistralai)
|
||||
|
||||
These ready-to-use checkpoints can be downloaded and used via the HuggingFace Hub:
|
||||
|
||||
```python
|
||||
>>> from transformers import AutoModelForCausalLM, AutoTokenizer
|
||||
>>> device = "cuda" # the device to load the model onto
|
||||
|
||||
>>> model = AutoModelForCausalLM.from_pretrained("mistralai/Mistral-7B-v0.1")
|
||||
>>> tokenizer = AutoTokenizer.from_pretrained("mistralai/Mistral-7B-v0.1")
|
||||
|
||||
>>> prompt = "My favourite condiment is"
|
||||
|
||||
>>> model_inputs = tokenizer([prompt], return_tensors="pt").to(device)
|
||||
>>> model.to(device)
|
||||
|
||||
>>> generated_ids = model.generate(**model_inputs, max_new_tokens=100, do_sample=True)
|
||||
>>> tokenizer.batch_decode(generated_ids)[0]
|
||||
"The expected outupt"
|
||||
```
|
||||
|
||||
Raw weights for `Mistral-7B-v0.1` and `Mistral-7B-Instruct-v0.1` can be downloaded from:
|
||||
|
||||
| Model Name | Checkpoint |
|
||||
|----------------------------|-----------------------------------------------------------------------------------------|
|
||||
| `Mistral-7B-v0.1` | [Raw Checkpoint](https://files.mistral-7b-v0-1.mistral.ai/mistral-7B-v0.1.tar) |
|
||||
| `Mistral-7B-Instruct-v0.1` | [Raw Checkpoint](https://files.mistral-7b-v0-1.mistral.ai/mistral-7B-instruct-v0.1.tar) |
|
||||
|
||||
|
||||
To use these raw checkpoints with HuggingFace you can use the `convert_mistral_weights_to_hf.py` script to convert them to the HuggingFace format:
|
||||
|
||||
```bash
|
||||
python src/transformers/models/mistral/convert_mistral_weights_to_hf.py \
|
||||
--input_dir /path/to/downloaded/mistral/weights --model_size 7B --output_dir /output/path
|
||||
```
|
||||
|
||||
You can then load the converted model from the `output/path`:
|
||||
|
||||
```python
|
||||
from transformers import MistralForCausalLM, LlamaTokenzier
|
||||
|
||||
tokenizer = LlamaTokenizer.from_pretrained("/output/path")
|
||||
model = MistralForCausalLM.from_pretrained("/output/path")
|
||||
```

r"""
|
||||
This is the configuration class to store the configuration of a [`MistralModel`]. It is used to instantiate an
|
||||
Mistral model according to the specified arguments, defining the model architecture. Instantiating a configuration
|
||||
with the defaults will yield a similar configuration to that of the Mistral-7B-v0.1 or Mistral-7B-Instruct-v0.1.
|
||||
|
||||
[mistralai/Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1)
|
||||
[mistralai/Mistral-7B-Instruct-v0.1](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.1)
|
||||
|
||||
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
||||
documentation from [`PretrainedConfig`] for more information.
|
||||
|
||||
|
||||
Args:
|
||||
vocab_size (`int`, *optional*, defaults to 32000):
|
||||
Vocabulary size of the Mistral model. Defines the number of different tokens that can be represented by the
|
||||
`inputs_ids` passed when calling [`MistralModel`]
|
||||
hidden_size (`int`, *optional*, defaults to 4096):
|
||||
Dimension of the hidden representations.
|
||||
intermediate_size (`int`, *optional*, defaults to 14336):
|
||||
Dimension of the MLP representations.
|
||||
num_hidden_layers (`int`, *optional*, defaults to 32):
|
||||
Number of hidden layers in the Transformer encoder.
|
||||
num_attention_heads (`int`, *optional*, defaults to 32):
|
||||
Number of attention heads for each attention layer in the Transformer encoder.
|
||||
num_key_value_heads (`int`, *optional*, defaults to 8):
|
||||
This is the number of key_value heads that should be used to implement Grouped Query Attention. If
|
||||
`num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
|
||||
`num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
|
||||
converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
|
||||
by meanpooling all the original heads within that group. For more details checkout [this
|
||||
paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `8`.
|
||||
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
||||
The non-linear activation function (function or string) in the decoder.
|
||||
max_position_embeddings (`int`, *optional*, defaults to 4096*32):
|
||||
The maximum sequence length that this model might ever be used with. Mistral's sliding window attention
|
||||
allows sequence of up to 4096*32 tokens.
|
||||
initializer_range (`float`, *optional*, defaults to 0.02):
|
||||
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
||||
rms_norm_eps (`float`, *optional*, defaults to 1e-12):
|
||||
The epsilon used by the rms normalization layers.
|
||||
use_cache (`bool`, *optional*, defaults to `True`):
|
||||
Whether or not the model should return the last key/values attentions (not used by all models). Only
|
||||
relevant if `config.is_decoder=True`.
|
||||
tie_word_embeddings(`bool`, *optional*, defaults to `False`):
|
||||
Whether to tie weight embeddings
|
||||
rope_theta (`float`, *optional*, defaults to 10000.0):
|
||||
The base period of the RoPE embeddings.
|
||||
sliding_window (`int`, *optional*, defaults to 4096):
|
||||
Sliding window attention window size. If not specified, will default to `4096`.
|
||||
|
||||
Example:
|
||||
|
||||
```python
|
||||
>>> from transformers import MistralModel, MistralConfig
|
||||
|
||||
>>> # Initializing a Mistral 7B style configuration

input_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`):
|

Indices of input sequence tokens in the vocabulary. Padding will be ignored by default should you provide
|
||||
it.
|
||||
|
||||
Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
|
||||
[`PreTrainedTokenizer.__call__`] for details.
|
||||
|
||||
[What are input IDs?](../glossary#input-ids)
|
||||
attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):
|
||||
Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
|
||||
|
||||
- 1 for tokens that are **not masked**,
|
||||
- 0 for tokens that are **masked**.
|
||||
|
||||
[What are attention masks?](../glossary#attention-mask)
|

Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and

[`PreTrainedTokenizer.__call__`] for details.
|
||||
|
||||
If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
|
||||
`past_key_values`).
|
||||
|
||||
If you want to change padding behavior, you should read [`modeling_opt._prepare_decoder_attention_mask`]
|
||||
and modify to your needs. See diagram 1 in [the paper](https://arxiv.org/abs/1910.13461) for more
|
||||
information on the default strategy.
|
||||
|
||||
- 1 indicates the head is **not masked**,
|
||||
- 0 indicates the head is **masked**.
|
||||
position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
|
||||
Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0,
|
||||
config.n_positions - 1]`.
|
||||
|

[What are position IDs?](../glossary#position-ids)
|

past_key_values (`tuple(tuple(torch.FloatTensor))`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`):
|
||||
Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape
|
||||
`(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape
|
||||
`(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.
|
||||
|
||||
Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
|
||||
blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
|
||||
|
||||
If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
|
||||
don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
|
||||
`decoder_input_ids` of shape `(batch_size, sequence_length)`.
|
||||
inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
|
||||
Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
|
||||
is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
|
||||
model's internal embedding lookup matrix.
|
||||
use_cache (`bool`, *optional*):
|
||||
If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
|

`past_key_values`).
|
||||
output_attentions (`bool`, *optional*):
|
||||
Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
|
||||
tensors for more detail.
|

output_hidden_states (`bool`, *optional*):
|
||||
Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
|
||||
more detail.
|
||||
return_dict (`bool`, *optional*):
|

Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.

Since it does classification on the last token, it requires to know the position of the last token. If a
|
||||
`pad_token_id` is defined in the configuration, it finds the last token that is not a padding token in each row. If
|
||||
no `pad_token_id` is defined, it simply takes the last value in each row of the batch. Since it cannot guess the
|
||||
padding tokens when `inputs_embeds` are passed instead of `input_ids`, it does the same (take the last value in
|
||||
each row of the batch).
