# Mistral

[Mistral](https://huggingface.co/papers/2310.06825) is a 7B parameter language model, available as a pretrained and instruction-tuned variant, focused on balancing
the scaling costs of large models with performance and efficient inference. This model uses sliding window attention (SWA) trained with a 8K context length and a fixed cache size to handle longer sequences more effectively. Grouped-query attention (GQA) speeds up inference and reduces memory requirements. Mistral also features a byte-fallback BPE tokenizer to improve token handling and efficiency by ensuring characters are never mapped to out-of-vocabulary tokens.

You can find all the original Mistral checkpoints under the [Mistral AI_](https://huggingface.co/mistralai) organization.

> [!TIP]
> Click on the Mistral models in the right sidebar for more examples of how to apply Mistral to different language tasks.

The example below demonstrates how to chat with [Pipeline](/docs/transformers/v5.0.0/en/main_classes/pipelines#transformers.Pipeline) or the [AutoModel](/docs/transformers/v5.0.0/en/model_doc/auto#transformers.AutoModel), and from the command line.

```python
>>> import torch
>>> from transformers import pipeline

>>> messages = [
...     {"role": "user", "content": "What is your favourite condiment?"},
...     {"role": "assistant", "content": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"},
...     {"role": "user", "content": "Do you have mayonnaise recipes?"}
... ]

>>> chatbot = pipeline("text-generation", model="mistralai/Mistral-7B-Instruct-v0.3", dtype=torch.bfloat16, device=0)
>>> chatbot(messages)
```

```python
>>> import torch
>>> from transformers import AutoModelForCausalLM, AutoTokenizer

>>> model = AutoModelForCausalLM.from_pretrained("mistralai/Mistral-7B-Instruct-v0.3", dtype=torch.bfloat16, attn_implementation="sdpa", device_map="auto")
>>> tokenizer = AutoTokenizer.from_pretrained("mistralai/Mistral-7B-Instruct-v0.3")

>>> messages = [
...     {"role": "user", "content": "What is your favourite condiment?"},
...     {"role": "assistant", "content": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"},
...     {"role": "user", "content": "Do you have mayonnaise recipes?"}
... ]

>>> model_inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)

>>> generated_ids = model.generate(model_inputs, max_new_tokens=100, do_sample=True)
>>> tokenizer.batch_decode(generated_ids)[0]
"Mayonnaise can be made as follows: (...)"
```

```python
echo -e "My favorite condiment is" | transformers chat mistralai/Mistral-7B-v0.3 --dtype auto --device 0 --attn_implementation flash_attention_2
```

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.

The example below uses [bitsandbytes](../quantization/bitsandbytes) to only quantize the weights to 4-bits.

```python
>>> import torch
>>> from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig

>>> # specify how to quantize the model
>>> quantization_config = BitsAndBytesConfig(
...         load_in_4bit=True,
...         bnb_4bit_quant_type="nf4",
...         bnb_4bit_compute_dtype="torch.float16",
... )

>>> model = AutoModelForCausalLM.from_pretrained("mistralai/Mistral-7B-Instruct-v0.3", quantization_config=True, dtype=torch.bfloat16, device_map="auto")
>>> tokenizer = AutoTokenizer.from_pretrained("mistralai/Mistral-7B-Instruct-v0.3")

>>> prompt = "My favourite condiment is"

>>> messages = [
...     {"role": "user", "content": "What is your favourite condiment?"},
...     {"role": "assistant", "content": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"},
...     {"role": "user", "content": "Do you have mayonnaise recipes?"}
... ]

>>> model_inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)

>>> generated_ids = model.generate(model_inputs, max_new_tokens=100, do_sample=True)
>>> tokenizer.batch_decode(generated_ids)[0]
"The expected output"
```

Use the [AttentionMaskVisualizer](https://github.com/huggingface/transformers/blob/beb9b5b02246b9b7ee81ddf938f93f44cfeaad19/src/transformers/utils/attention_visualizer.py#L139) to better understand what tokens the model can and cannot attend to.

```py
>>> from transformers.utils.attention_visualizer import AttentionMaskVisualizer

>>> visualizer = AttentionMaskVisualizer("mistralai/Mistral-7B-Instruct-v0.3")
>>> visualizer("Do you have mayonnaise recipes?")
```

#### transformers.MistralConfig[[transformers.MistralConfig]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/models/mistral/configuration_mistral.py#L24)

This is the configuration class to store the configuration of a [MistralModel](/docs/transformers/v5.0.0/en/model_doc/mistral#transformers.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](/docs/transformers/v5.0.0/en/main_classes/configuration#transformers.PreTrainedConfig) and can be used to control the model outputs. Read the
documentation from [PreTrainedConfig](/docs/transformers/v5.0.0/en/main_classes/configuration#transformers.PreTrainedConfig) for more information.

```python
>>> from transformers import MistralModel, MistralConfig

>>> # Initializing a Mistral 7B style configuration
>>> configuration = MistralConfig()

>>> # Initializing a model from the Mistral 7B style configuration
>>> model = MistralModel(configuration)

>>> # Accessing the model configuration
>>> configuration = model.config
```

**Parameters:**

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](/docs/transformers/v5.0.0/en/model_doc/mistral#transformers.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_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, check out [this paper](https://huggingface.co/papers/2305.13245). If it is not specified, will default to `8`.

head_dim (`int`, *optional*, defaults to `hidden_size // num_attention_heads`) : The attention head dimension.

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.

attention_dropout (`float`, *optional*, defaults to 0.0) : The dropout ratio for the attention probabilities.

## MistralCommonBackend[[transformers.MistralCommonBackend]]

#### transformers.MistralCommonBackend[[transformers.MistralCommonBackend]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L186)

Class to wrap `mistral-common` tokenizers.

`mistral-common` is the official tokenizer library for Mistral AI models. To use it, you need to install it with:

```bash
pip install transformers[mistral-common]
```

Otherwise the tokenizer falls back to the Transformers implementation of the tokenizer.

For more info on `mistral-common`, see [mistral-common](https://github.com/mistralai/mistral-common).

This class is a wrapper around a `mistral_common.tokens.tokenizers.mistral.MistralTokenizer`.
It provides a Hugging Face compatible interface to tokenize using the official mistral-common tokenizer and inherits from the `PreTrainedTokenizerBase` class.

Here are the key behavior differences with the `PythonBackend` class:

- Pair of sequences are not supported. The signature has been kept for compatibility but all arguments related to pair of sequences are ignored. The return values for pairs are returned as `None`.
- The `is_split_into_words` argument is not supported.
- It is not possible to add new tokens to the tokenizer. Special tokens are handled differently from Transformers. In `mistral-common`, special tokens are never encoded directly. This means that: `tokenizer.encode("")` will not return the ID of the `` token. Instead, it will return a list of IDs corresponding to the tokenization of the string `""`. For more information, see the [mistral-common documentation](https://mistralai.github.io/mistral-common/usage/tokenizers/#special-tokens).

If you have suggestions to improve this class, please open an issue on the [mistral-common GitHub repository](https://github.com/mistralai/mistral-common/issues) if it is related to the tokenizer or on the [Transformers GitHub repository](https://github.com/huggingface/transformers/issues) if it is related to the Hugging Face interface.

`MistralCommonBackend` does not implement `add_special_tokens` by design.

If you would like this behaviour to be implemented, please open an issue in the `Transformers` or `mistral-common` repositories to request it.
#### add_tokens[[transformers.MistralCommonBackend.add_tokens]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1604)

`MistralCommonBackend` does not implement `add_special_tokens` by design.

If you would like this behaviour to be implemented, please open an issue in the `Transformers` or `mistral-common` repositories to request it.
#### apply_chat_template[[transformers.MistralCommonBackend.apply_chat_template]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1041)

Converts a list of dictionaries with `"role"` and `"content"` keys to a list of token
ids.

**Parameters:**

conversation (Union[List[Dict[str, str]], List[List[Dict[str, str]]]]) : A list of dicts with "role" and "content" keys, representing the chat history so far.

tools (`List[Union[Dict, Callable]]`, *optional*) : A list of tools (callable functions) that will be accessible to the model. If the template does not support function calling, this argument will have no effect. Each tool should be passed as a JSON Schema, giving the name, description and argument types for the tool. See our [chat templating guide](https://huggingface.co/docs/transformers/main/en/chat_templating#automated-function-conversion-for-tool-use) for more information.

add_generation_prompt (`bool`, *optional*) : This argument is a no-op for `MistralCommonBackend`. However, it cannot be used at the same time as `continue_final_message` to keep the API consistent. If any conversation ends with an assistant message, it will raise an error. In such cases, use `continue_final_message` instead.

continue_final_message (bool, *optional*) : If this is set, the chat will be formatted so that the final message in the chat is open-ended, without any EOS tokens. The model will continue this message rather than starting a new one. This allows you to "prefill" part of the model's response for it. Cannot be used at the same time as `add_generation_prompt`.

tokenize (`bool`, defaults to `True`) : Whether to tokenize the output. If `False`, the output will be a string.

padding (`bool`, `str` or [PaddingStrategy](/docs/transformers/v5.0.0/en/internal/file_utils#transformers.utils.PaddingStrategy), *optional*, defaults to `False`) : Select a strategy to pad the returned sequences (according to the model's padding side and padding index) among:  - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single sequence if provided). - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different lengths).

truncation (`bool`, defaults to `False`) : Whether to truncate sequences at the maximum length. Has no effect if tokenize is `False`.

max_length (`int`, *optional*) : Maximum length (in tokens) to use for padding or truncation. Has no effect if tokenize is `False`. If not specified, the tokenizer's `max_length` attribute will be used as a default.

return_tensors (`str` or [TensorType](/docs/transformers/v5.0.0/en/internal/file_utils#transformers.TensorType), *optional*) : If set, will return tensors of a particular framework. Has no effect if tokenize is `False`. Acceptable values are: - `'pt'`: Return PyTorch `torch.Tensor` objects.

return_dict (`bool`, defaults to `False`) : Whether to return a dictionary with named outputs. Has no effect if tokenize is `False`. If at least one conversation contains an image, its pixel values will be returned in the `pixel_values` key.

kwargs (additional keyword arguments, *optional*) : Not supported by `MistralCommonBackend.apply_chat_template`. Will raise an error if used.

**Returns:**

``Union[str, list[int], list[str], list[list[int]], BatchEncoding]``

The tokenized chat so far, including control tokens. This output is ready to pass to the model, either directly or via methods like `generate()`.
#### batch_decode[[transformers.MistralCommonBackend.batch_decode]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L515)

Convert a list of lists of token ids into a list of strings by calling decode.

This method is provided for backwards compatibility. The `decode` method now handles batched input natively,
so you can use `decode` directly instead of `batch_decode`.

**Parameters:**

sequences (`Union[list[int], list[list[int]], np.ndarray, torch.Tensor]`) : List of tokenized input ids. Can be obtained using the `__call__` method.

skip_special_tokens (`bool`, *optional*, defaults to `False`) : Whether or not to remove special tokens in the decoding.

clean_up_tokenization_spaces (`bool`, *optional*) : Whether or not to clean up the tokenization spaces. If `None`, will default to `self.clean_up_tokenization_spaces`.

kwargs (additional keyword arguments, *optional*) : Not supported by `MistralCommonBackend.batch_decode`. Will raise an error if used.

**Returns:**

``list[str]``

The list of decoded sentences.
#### build_inputs_with_special_tokens[[transformers.MistralCommonBackend.build_inputs_with_special_tokens]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1252)

Build model inputs from a sequence by adding special tokens.

This method dynamically builds inputs based on the tokenizer's `mode`:
- `"test"`: seq0 [EOS]
- `"finetuning"`: [BOS] seq0

**Parameters:**

token_ids_0 (`list[int]`) : List of IDs to which the special tokens will be added.

token_ids_1 (`None`, *optional*) : None, kept to match Transformers' signature.

**Returns:**

``list[int]``

List of input IDs with the appropriate special tokens.
#### convert_added_tokens[[transformers.MistralCommonBackend.convert_added_tokens]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1617)

`MistralCommonBackend` does not implement `convert_added_tokens` by design.

If you would like this behaviour to be implemented, please open an issue in the `Transformers` or `mistral-common` repositories to request it.
#### create_token_type_ids_from_sequences[[transformers.MistralCommonBackend.create_token_type_ids_from_sequences]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1281)

Create a mask of zeroes from the token ids with special tokens added.

Kept to match Transformers' implementation.

**Parameters:**

token_ids_0 (`list[int]`) : List of IDs.

token_ids_1 (`None`, *optional*) : None, kept to match Transformers' signature.

**Returns:**

``list[int]``

Token type IDs according to the configured pattern.

tokens and clean up tokenization spaces.

**Parameters:**

token_ids (`Union[int, list[int], list[list[int]], np.ndarray, torch.Tensor]`) : A single sequence or a batch (list of sequences) of tokenized input ids. Can be obtained using the `__call__` method.

skip_special_tokens (`bool`, *optional*, defaults to `False`) : Whether or not to remove special tokens in the decoding.

clean_up_tokenization_spaces (`bool`, *optional*) : Whether or not to clean up the tokenization spaces. If `None`, will default to `self.clean_up_tokenization_spaces`.

``Union[str, list[str]]``

The decoded string for a single sequence, or a list of decoded strings for a
batch of sequences.
#### encode[[transformers.MistralCommonBackend.encode]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L365)

Converts a string to a sequence of ids (integer), using the tokenizer and vocabulary.

**Parameters:**

text (`str` or `list[int]`) : The first sequence to be encoded. This can be a string or a list of integers (tokenized string ids).

text_pair (`None`, *optional*) : Not supported by `MistralCommonBackend.encode`. Kept to match `PreTrainedTokenizerBase.encode` signature. 

add_special_tokens (`bool`, *optional*, defaults to `True`) : Whether or not to add special tokens when encoding the sequences. This will use the underlying `PretrainedTokenizerBase.build_inputs_with_special_tokens` function, which defines which tokens are automatically added to the input ids. This is useful if you want to add `bos` or `eos` tokens automatically. When Tokenizer is loading with `finetuning` mode it adds both `bos` and `eos`. Else, for "test" mode it only adds `bos`.

padding (`bool`, `str` or [PaddingStrategy](/docs/transformers/v5.0.0/en/internal/file_utils#transformers.utils.PaddingStrategy), *optional*, defaults to `False`) : Activates and controls padding. Accepts the following values:  - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single sequence is provided). - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different lengths).

truncation (`bool`, `str` or [TruncationStrategy](/docs/transformers/v5.0.0/en/internal/tokenization_utils#transformers.tokenization_utils_base.TruncationStrategy), *optional*, defaults to `False`) : Activates and controls truncation. Accepts the following values:  - `True` or `'longest_first'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths greater than the model maximum admissible input size).

max_length (`int`, *optional*) : Controls the maximum length to use by one of the truncation/padding parameters.  If left unset or set to `None`, this will use the predefined model maximum length if a maximum length is required by one of the truncation/padding parameters. If the model has no specific maximum input length (like XLNet) truncation/padding to a maximum length will be deactivated.

stride (`int`, *optional*, defaults to 0) : If set to a number along with `max_length`, the overflowing tokens returned when `return_overflowing_tokens=True` will contain some tokens from the end of the truncated sequence returned to provide some overlap between truncated and overflowing sequences. The value of this argument defines the number of overlapping tokens.

pad_to_multiple_of (`int`, *optional*) : If set will pad the sequence to a multiple of the provided value. Requires `padding` to be activated. This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability `>= 7.5` (Volta).

padding_side (`str`, *optional*) : The side on which the model should have padding applied. Should be selected between ['right', 'left']. Default value is picked from the class attribute of the same name.

return_tensors (`str` or [TensorType](/docs/transformers/v5.0.0/en/internal/file_utils#transformers.TensorType), *optional*) : If set, will return tensors instead of list of python integers. Acceptable values are:  - `'pt'`: Return PyTorch `torch.Tensor` objects. 

- ****kwargs** : Not supported by `MistralCommonBackend.encode`. Will raise an error if used.

**Returns:**

``list[int]`, `torch.Tensor``

The tokenized ids of the text.
#### from_pretrained[[transformers.MistralCommonBackend.from_pretrained]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1405)

Instantiate a `MistralCommonBackend` from a predefined
tokenizer.

**Parameters:**

pretrained_model_name_or_path (`str` or `os.PathLike`) : Can be either:  - A string, the *model id* of a predefined tokenizer hosted inside a model repo on huggingface.co. - A path to a *directory* containing the tokenizer config, for instance saved using the `MistralCommonBackend.tokenization_mistral_common.save_pretrained` method, e.g., `./my_model_directory/`.

mode (`Union[str, ValidationMode]`, *optional*, defaults to `ValidationMode.test`) : Validation mode for the `MistralTokenizer` tokenizer. Possible values are: - `"finetuning"` or `ValidationMode.finetuning`: The fine-tuning mode. - `"test"` or `ValidationMode.test`: The test mode. It changes how the tokenizer validates the input and prepares the request to the model.

cache_dir (`str` or `os.PathLike`, *optional*) : Path to a directory in which a downloaded predefined tokenizer vocabulary files should be cached if the standard cache should not be used.

force_download (`bool`, *optional*, defaults to `False`) : Whether or not to force the (re-)download the vocabulary files and override the cached versions if they exist.

token (`str` or *bool*, *optional*) : The token to use as HTTP bearer authorization for remote files. If `True`, will use the token generated when running `hf auth login` (stored in `~/.huggingface`).

local_files_only (`bool`, *optional*, defaults to `False`) : Whether or not to only rely on local files and not to attempt to download any files.

revision (`str`, *optional*, defaults to `"main"`) : The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, so `revision` can be any identifier allowed by git.

max_length (`int`, *optional*) : Controls the maximum length to use by one of the truncation/padding parameters.  If left unset or set to `None`, this will use the predefined model maximum length if a maximum length is required by one of the truncation/padding parameters. If the model has no specific maximum input length (like XLNet) truncation/padding to a maximum length will be deactivated.

padding_side (`str`, *optional*, defaults to `"left"`) : The side on which the model should have padding applied. Should be selected between ['right', 'left']. Default value is picked from the class attribute of the same name.

truncation_side (`str`, *optional*, defaults to `"right"`) : The side on which the model should have truncation applied. Should be selected between ['right', 'left'].

model_input_names (`List[str]`, *optional*) : The list of inputs accepted by the forward pass of the model (like `"token_type_ids"` or `"attention_mask"`). Default value is picked from the class attribute of the same name.

clean_up_tokenization_spaces (`bool`, *optional*, defaults to `False`) : Whether or not the model should clean up the spaces that were added when splitting the input text during the tokenization process.

kwargs (additional keyword arguments, *optional*) : Not supported by `MistralCommonBackend.from_pretrained`. Will raise an error if used.
#### get_chat_template[[transformers.MistralCommonBackend.get_chat_template]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1626)

`MistralCommonBackend` does not implement `get_chat_template` by design as `mistral-common` does not use chat templates.
#### get_special_tokens_mask[[transformers.MistralCommonBackend.get_special_tokens_mask]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L694)

special tokens using the tokenizer `prepare_for_model` or `encode_plus` methods.

**Parameters:**

token_ids_0 (`list[int]`) : List of ids of the sequence.

token_ids_1 (`None`, *optional*) : None, kept to match Transformers' implementation.

already_has_special_tokens (`bool`, *optional*, defaults to `False`) : Whether or not the token list is already formatted with special tokens for the model.

**Returns:**

`A list of integers in the range [0, 1]`

#### get_vocab[[transformers.MistralCommonBackend.get_vocab]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L339)

Returns the vocabulary as a dictionary of token to index.

This is a lossy conversion. There may be multiple token ids that decode to the same
string due to partial UTF-8 byte sequences being converted to �.

**Returns:**

``Dict[str, int]``

#### num_special_tokens_to_add[[transformers.MistralCommonBackend.num_special_tokens_to_add]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1305)

Returns the number of added tokens when encoding a sequence with special tokens.

This encodes a dummy input and checks the number of added tokens, and is therefore not efficient. Do not put
this inside your training loop.

#### prepare_for_model[[transformers.MistralCommonBackend.prepare_for_model]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L847)

Prepares a sequence of input id so that it can be used by the model. It
adds special tokens, truncates sequences if overflowing while taking into account the special tokens and
manages a moving window (with user defined stride) for overflowing tokens.

**Parameters:**

ids (`list[int]`) : Tokenized input ids of the first sequence.

pair_ids (`None`, *optional*) : Not supported by `MistralCommonBackend`. Kept to match the interface of `PreTrainedTokenizerBase`. 

add_special_tokens (`bool`, *optional*, defaults to `True`) : Whether or not to add special tokens when encoding the sequences. This will use the underlying `PretrainedTokenizerBase.build_inputs_with_special_tokens` function, which defines which tokens are automatically added to the input ids. This is useful if you want to add `bos` or `eos` tokens automatically. When Tokenizer is loading with `finetuning` mode it adds both `bos` and `eos`. Else, for "test" mode it only adds `bos`.

padding (`bool`, `str` or [PaddingStrategy](/docs/transformers/v5.0.0/en/internal/file_utils#transformers.utils.PaddingStrategy), *optional*, defaults to `False`) : Activates and controls padding. Accepts the following values:  - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single sequence is provided). - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different lengths).

truncation (`bool`, `str` or [TruncationStrategy](/docs/transformers/v5.0.0/en/internal/tokenization_utils#transformers.tokenization_utils_base.TruncationStrategy), *optional*, defaults to `False`) : Activates and controls truncation. Accepts the following values:  - `True` or `'longest_first'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths greater than the model maximum admissible input size).

max_length (`int`, *optional*) : Controls the maximum length to use by one of the truncation/padding parameters.  If left unset or set to `None`, this will use the predefined model maximum length if a maximum length is required by one of the truncation/padding parameters. If the model has no specific maximum input length (like XLNet) truncation/padding to a maximum length will be deactivated.

stride (`int`, *optional*, defaults to 0) : If set to a number along with `max_length`, the overflowing tokens returned when `return_overflowing_tokens=True` will contain some tokens from the end of the truncated sequence returned to provide some overlap between truncated and overflowing sequences. The value of this argument defines the number of overlapping tokens.

pad_to_multiple_of (`int`, *optional*) : If set will pad the sequence to a multiple of the provided value. Requires `padding` to be activated. This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability `>= 7.5` (Volta).

padding_side (`str`, *optional*) : The side on which the model should have padding applied. Should be selected between ['right', 'left']. Default value is picked from the class attribute of the same name.

return_tensors (`str` or [TensorType](/docs/transformers/v5.0.0/en/internal/file_utils#transformers.TensorType), *optional*) : If set, will return tensors instead of list of python integers. Acceptable values are:  - `'pt'`: Return PyTorch `torch.Tensor` objects. 

return_token_type_ids (`bool`, *optional*) : Whether to return token type IDs. For `MistralCommonBackend` it returns a list of zeros of the sequence length as only one sequence is supported.  [What are token type IDs?](../glossary#token-type-ids)

return_attention_mask (`bool`, *optional*) : Whether to return the attention mask. If left to the default, will return the attention mask according to the specific tokenizer's default, defined by the `return_outputs` attribute.  [What are attention masks?](../glossary#attention-mask)

return_overflowing_tokens (`bool`, *optional*, defaults to `False`) : Whether or not to return overflowing token sequences. If a pair of sequences of input ids (or a batch of pairs) is provided with `truncation_strategy = longest_first` or `True`, an error is raised instead of returning overflowing tokens.

return_special_tokens_mask (`bool`, *optional*, defaults to `False`) : Whether or not to return special tokens mask information.

return_length  (`bool`, *optional*, defaults to `False`) : Whether or not to return the lengths of the encoded inputs.

verbose (`bool`, *optional*, defaults to `True`) : Whether or not to print more information and warnings.

return_offsets_mapping (`Literal[False]`, *optional*) : False, kept to match Transformers' signature.

split_special_tokens (`Literal[False]`, *optional*) : False, kept to match Transformers' signature.

**Returns:**

`[BatchEncoding](/docs/transformers/v5.0.0/en/main_classes/tokenizer#transformers.BatchEncoding)`

#### save_vocabulary[[transformers.MistralCommonBackend.save_vocabulary]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0/src/transformers/tokenization_mistral_common.py#L1642)

`MistralCommonBackend` does not implement `save_vocabulary` by design.

This is because `mistral-common` is configured by one tokenizer file. If you'd like to save the vocabulary, please consider using the `save_pretrained` method instead.

the latter silently ignores them.

Example:

```python

>>> model = MistralForCausalLM.from_pretrained("meta-mistral/Mistral-2-7b-hf")
>>> tokenizer = AutoTokenizer.from_pretrained("meta-mistral/Mistral-2-7b-hf")

  Indices of input sequence tokens in the vocabulary. Padding will be ignored by default.

  Indices can be obtained using [AutoTokenizer](/docs/transformers/v5.0.0/en/model_doc/auto#transformers.AutoTokenizer). See [PreTrainedTokenizer.encode()](/docs/transformers/v5.0.0/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase.encode) and

- **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)
- **position_ids** (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*) --

  [What are position IDs?](../glossary#position-ids)
- **past_key_values** (`~cache_utils.Cache`, *optional*) --
  Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
  blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values`
  returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.

  Only [Cache](/docs/transformers/v5.0.0/en/internal/generation_utils#transformers.Cache) instance is allowed as input, see our [kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache).
  If no `past_key_values` are passed, [DynamicCache](/docs/transformers/v5.0.0/en/internal/generation_utils#transformers.DynamicCache) will be initialized by default.

  The model will output the same cache format that is fed as input.

  If `past_key_values` are used, the user is expected to input only unprocessed `input_ids` (those that don't
  have their past key value states given to this model) of shape `(batch_size, unprocessed_length)` instead of all `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.
- **start_positions** (`torch.LongTensor` of shape `(batch_size,)`, *optional*) --
  Labels for position (index) of the start of the labelled span for computing the token classification loss.
  Positions are clamped to the length of the sequence (`sequence_length`). Position outside of the sequence
  are not taken into account for computing the loss.
- **end_positions** (`torch.LongTensor` of shape `(batch_size,)`, *optional*) --
  Labels for position (index) of the end of the labelled span for computing the token classification loss.
  Positions are clamped to the length of the sequence (`sequence_length`). Position outside of the sequence
  are not taken into account for computing the loss.0[transformers.modeling_outputs.QuestionAnsweringModelOutput](/docs/transformers/v5.0.0/en/main_classes/output#transformers.modeling_outputs.QuestionAnsweringModelOutput) or `tuple(torch.FloatTensor)`A [transformers.modeling_outputs.QuestionAnsweringModelOutput](/docs/transformers/v5.0.0/en/main_classes/output#transformers.modeling_outputs.QuestionAnsweringModelOutput) or a tuple of
`torch.FloatTensor` (if `return_dict=False` is passed or when `config.return_dict=False`) comprising various
elements depending on the configuration (`None`) and inputs.

- **loss** (`torch.FloatTensor` of shape `(1,)`, *optional*, returned when `labels` is provided) -- Total span extraction loss is the sum of a Cross-Entropy for the start and end positions.
- **start_logits** (`torch.FloatTensor` of shape `(batch_size, sequence_length)`) -- Span-start scores (before SoftMax).
- **end_logits** (`torch.FloatTensor` of shape `(batch_size, sequence_length)`) -- Span-end scores (before SoftMax).
- **hidden_states** (`tuple(torch.FloatTensor)`, *optional*, returned when `output_hidden_states=True` is passed or when `config.output_hidden_states=True`) -- Tuple of `torch.FloatTensor` (one for the output of the embeddings, if the model has an embedding layer, +
  one for the output of each layer) of shape `(batch_size, sequence_length, hidden_size)`.

  Hidden-states of the model at the output of each layer plus the optional initial embedding outputs.
- **attentions** (`tuple(torch.FloatTensor)`, *optional*, returned when `output_attentions=True` is passed or when `config.output_attentions=True`) -- Tuple of `torch.FloatTensor` (one for each layer) of shape `(batch_size, num_heads, sequence_length,
  sequence_length)`.

  Attentions weights after the attention softmax, used to compute the weighted average in the self-attention
  heads.
The `GenericForQuestionAnswering` forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module`
instance afterwards instead of this since the former takes care of running the pre and post processing steps while
the latter silently ignores them.
