Output type of [`YolosForObjectDetection`].
Args:
loss (`torch.FloatTensor` of shape `(1,)`, *optional*, returned when `labels` are provided)):
Total loss as a linear combination of a negative log-likehood (cross-entropy) for class prediction and a
bounding box loss. The latter is defined as a linear combination of the L1 loss and the generalized
scale-invariant IoU loss.
loss_dict (`Dict`, *optional*):
A dictionary containing the individual losses. Useful for logging.
logits (`torch.FloatTensor` of shape `(batch_size, num_queries, num_classes + 1)`):
Classification logits (including no-object) for all queries.
pred_boxes (`torch.FloatTensor` of shape `(batch_size, num_queries, 4)`):
Normalized boxes coordinates for all queries, represented as (center_x, center_y, width, height). These
values are normalized in [0, 1], relative to the size of each individual image in the batch (disregarding
possible padding). You can use [`~YolosImageProcessor.post_process`] to retrieve the unnormalized bounding
boxes.
auxiliary_outputs (`list[Dict]`, *optional*):
Optional, only returned when auxilary losses are activated (i.e. `config.auxiliary_loss` is set to `True`)
and labels are provided. It is a list of dictionaries containing the two above keys (`logits` and
`pred_boxes`) for each decoder layer.
last_hidden_state (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
Sequence of hidden-states at the output of the last layer of the decoder of the model.
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 maximum id for a class in your dataset. For example, COCO has a `max_obj_id` of 90, so we pass `num_classes` to
be 91. As another example, for a dataset that has a single class with `id` 1, you should pass `num_classes` to be 2

"""
Pipeline that aims at extracting spoken text contained within some audio.
The input can be either a raw waveform or a audio file. In case of the audio file, ffmpeg should be installed for
to support multiple audio formats
Example:
```python
>>> from transformers import pipeline
>>> transcriber = pipeline(model="openai/whisper-base")
>>> transcriber("https://huggingface.co/datasets/Narsil/asr_dummy/resolve/main/1.flac")
{'text': ' He hoped there would be stew for dinner, turnips and carrots and bruised potatoes and fat mutton pieces to be ladled out in thick, peppered flour-fatten sauce.'}
```
Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial)
Arguments:
model ([`PreTrainedModel`] or [`TFPreTrainedModel`]):
The model that will be used by the pipeline to make predictions. This needs to be a model inheriting from
[`PreTrainedModel`] for PyTorch and [`TFPreTrainedModel`] for TensorFlow.
feature_extractor ([`SequenceFeatureExtractor`]):
The feature extractor that will be used by the pipeline to encode waveform for the model.
tokenizer ([`PreTrainedTokenizer`]):
The tokenizer that will be used by the pipeline to encode data for the model. This object inherits from
[`PreTrainedTokenizer`].
decoder (`pyctcdecode.BeamSearchDecoderCTC`, *optional*):
[PyCTCDecode's
BeamSearchDecoderCTC](https://github.com/kensho-technologies/pyctcdecode/blob/2fd33dc37c4111417e08d89ccd23d28e9b308d19/pyctcdecode/decoder.py#L180)
can be passed for language model boosted decoding. See [`Wav2Vec2ProcessorWithLM`] for more information.
chunk_length_s (`float`, *optional*, defaults to 0):
The input length for in each chunk. If `chunk_length_s = 0` then chunking is disabled (default).
<Tip>
For more information on how to effectively use `chunk_length_s`, please have a look at the [ASR chunking
blog post](https://huggingface.co/blog/asr-chunking).
</Tip>
stride_length_s (`float`, *optional*, defaults to `chunk_length_s / 6`):
The length of stride on the left and right of each chunk. Used only with `chunk_length_s > 0`. This enables
the model to *see* more context and infer letters better than without this context but the pipeline
discards the stride bits at the end to make the final reconstitution as perfect as possible.
<Tip>
For more information on how to effectively use `stride_length_s`, please have a look at the [ASR chunking
blog post](https://huggingface.co/blog/asr-chunking).
</Tip>
framework (`str`, *optional*):
The framework to use, either `"pt"` for PyTorch or `"tf"` for TensorFlow. The specified framework must be
installed. If no framework is specified, will default to the one currently installed. If no framework is
specified and both frameworks are installed, will default to the framework of the `model`, or to PyTorch if
no model is provided.
device (Union[`int`, `torch.device`], *optional*):
Device ordinal for CPU/GPU supports. Setting this to `None` will leverage CPU, a positive will run the
model on the associated CUDA device id.
torch_dtype (Union[`int`, `torch.dtype`], *optional*):
The data-type (dtype) of the computation. Setting this to `None` will use float32 precision. Set to
`torch.float16` or `torch.bfloat16` to use half-precision in the respective dtypes.

"""
Transcribe the audio sequence(s) given as inputs to text. See the [`AutomaticSpeechRecognitionPipeline`]
documentation for more information.
Args:
inputs (`np.ndarray` or `bytes` or `str` or `dict`):
The inputs is either :
- `str` that is either the filename of a local audio file, or a public URL address to download the
audio file. The file will be read at the correct sampling rate to get the waveform using
*ffmpeg*. This requires *ffmpeg* to be installed on the system.
- `bytes` it is supposed to be the content of an audio file and is interpreted by *ffmpeg* in the
same way.
- (`np.ndarray` of shape (n, ) of type `np.float32` or `np.float64`)
Raw audio at the correct sampling rate (no further check will be done)
- `dict` form can be used to pass raw audio sampled at arbitrary `sampling_rate` and let this
pipeline do the resampling. The dict must be in the format `{"sampling_rate": int, "raw":
np.array}` with optionally a `"stride": (left: int, right: int)` than can ask the pipeline to
treat the first `left` samples and last `right` samples to be ignored in decoding (but used at
inference to provide more context to the model). Only use `stride` with CTC models.
return_timestamps (*optional*, `str` or `bool`):
Only available for pure CTC models (Wav2Vec2, HuBERT, etc) and the Whisper model. Not available for
other sequence-to-sequence models.
For CTC models, timestamps can take one of two formats:
- `"char"`: the pipeline will return timestamps along the text for every character in the text. For
instance, if you get `[{"text": "h", "timestamp": (0.5, 0.6)}, {"text": "i", "timestamp": (0.7,
0.9)}]`, then it means the model predicts that the letter "h" was spoken after `0.5` and before
`0.6` seconds.
- `"word"`: the pipeline will return timestamps along the text for every word in the text. For
instance, if you get `[{"text": "hi ", "timestamp": (0.5, 0.9)}, {"text": "there", "timestamp":
(1.0, 1.5)}]`, then it means the model predicts that the word "hi" was spoken after `0.5` and
before `0.9` seconds.
For the Whisper model, timestamps can take one of two formats:
- `"word"`: same as above for word-level CTC timestamps. Word-level timestamps are predicted
through the *dynamic-time warping (DTW)* algorithm, an approximation to word-level timestamps
by inspecting the cross-attention weights.
- `True`: the pipeline will return timestamps along the text for *segments* of words in the text.
For instance, if you get `[{"text": " Hi there!", "timestamp": (0.5, 1.5)}]`, then it means the
model predicts that the segment "Hi there!" was spoken after `0.5` and before `1.5` seconds.
Note that a segment of text refers to a sequence of one or more words, rather than individual
words as with word-level timestamps.
generate_kwargs (`dict`, *optional*):
The dictionary of ad-hoc parametrization of `generate_config` to be used for the generation call. For a
complete overview of generate, check the [following
guide](https://huggingface.co/docs/transformers/en/main_classes/text_generation).
max_new_tokens (`int`, *optional*):
The maximum numbers of tokens to generate, ignoring the number of tokens in the prompt.
Return:
`Dict`: A dictionary with the following keys:
- **text** (`str`): The recognized text.
- **chunks** (*optional(, `List[Dict]`)
When using `return_timestamps`, the `chunks` will become a list containing all the various text
chunks identified by the model, *e.g.* `[{"text": "hi ", "timestamp": (0.5, 0.9)}, {"text":
"there", "timestamp": (1.0, 1.5)}]`. The original full text can roughly be recovered by doing
`"".join(chunk["text"] for chunk in output["chunks"])`.

Answers queries according to a table. The pipeline accepts several types of inputs which are detailed below:
- `pipeline(table, query)`
- `pipeline(table, [query])`
- `pipeline(table=table, query=query)`
- `pipeline(table=table, query=[query])`
- `pipeline({"table": table, "query": query})`
- `pipeline({"table": table, "query": [query]})`
- `pipeline([{"table": table, "query": query}, {"table": table, "query": query}])`
The `table` argument should be a dict or a DataFrame built from that dict, containing the whole table:
Example:
```python
data = {
"actors": ["brad pitt", "leonardo di caprio", "george clooney"],
"age": ["56", "45", "59"],
"number of movies": ["87", "53", "69"],
"date of birth": ["7 february 1967", "10 june 1996", "28 november 1967"],
}
```
This dictionary can be passed in as such, or can be converted to a pandas DataFrame:
Example:
```python
import pandas as pd
table = pd.DataFrame.from_dict(data)
```
Args:
table (`pd.DataFrame` or `Dict`):
Pandas DataFrame or dictionary that will be converted to a DataFrame containing all the table values.
See above for an example of dictionary.
query (`str` or `List[str]`):
Query or list of queries that will be sent to the model alongside the table.
sequential (`bool`, *optional*, defaults to `False`):
Whether to do inference sequentially or as a batch. Batching is faster, but models like SQA require the
inference to be done sequentially to extract relations within sequences, given their conversational
nature.
padding (`bool`, `str` or [`~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 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`, `str` or [`TapasTruncationStrategy`], *optional*, defaults to `False`):
Activates and controls truncation. Accepts the following values:
- `True` or `'drop_rows_to_fit'`: 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. This will
truncate row by row, removing rows from the table.
- `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths
greater than the model maximum admissible input size).
Return:
A dictionary or a list of dictionaries containing results: Each result is a dictionary with the following
keys:
- **answer** (`str`) -- The answer of the query given the table. If there is an aggregator, the answer will
be preceded by `AGGREGATOR >`.
- **coordinates** (`List[Tuple[int, int]]`) -- Coordinates of the cells of the answers.
- **cells** (`List[str]`) -- List of strings made up of the answer cell values.
- **aggregator** (`str`) -- If the model has an aggregator, this returns the aggregator.

Add a dictionary of special tokens (eos, pad, cls, etc.) to the encoder and link them to class attributes. If
special tokens are NOT in the vocabulary, they are added to it (indexed starting from the last index of the
current vocabulary).
When adding new tokens to the vocabulary, you should make sure to also resize the token embedding matrix of the
model so that its embedding matrix matches the tokenizer.
In order to do that, please use the [`~PreTrainedModel.resize_token_embeddings`] method.
Using `add_special_tokens` will ensure your special tokens can be used in several ways:
- Special tokens can be skipped when decoding using `skip_special_tokens = True`.
- Special tokens are carefully handled by the tokenizer (they are never split), similar to `AddedTokens`.
- You can easily refer to special tokens using tokenizer class attributes like `tokenizer.cls_token`. This
makes it easy to develop model-agnostic training and fine-tuning scripts.
When possible, special tokens are already registered for provided pretrained models (for instance
[`BertTokenizer`] `cls_token` is already registered to be :obj*'[CLS]'* and XLM's one is also registered to be
`'</s>'`).
Args:
special_tokens_dict (dictionary *str* to *str* or `tokenizers.AddedToken`):
Keys should be in the list of predefined special attributes: [`bos_token`, `eos_token`, `unk_token`,
`sep_token`, `pad_token`, `cls_token`, `mask_token`, `additional_special_tokens`].
Tokens are only added if they are not already in the vocabulary (tested by checking if the tokenizer
assign the index of the `unk_token` to them).
replace_additional_special_tokens (`bool`, *optional*,, defaults to `True`):
If `True`, the existing list of additional special tokens will be replaced by the list provided in
`special_tokens_dict`. Otherwise, `self._additional_special_tokens` is just extended. In the former
case, the tokens will NOT be removed from the tokenizer's full vocabulary - they are only being flagged
as non-special tokens. Remember, this only affects which tokens are skipped during decoding, not the
`added_tokens_encoder` and `added_tokens_decoder`. This means that the previous
`additional_special_tokens` are still added tokens, and will not be split by the model.
Returns:
`int`: Number of tokens added to the vocabulary.

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 usefull if you want to add `bos` or `eos` tokens
automatically.
padding (`bool`, `str` or [`~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 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`, `str` or [`~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. This will
truncate token by token, removing a token from the longest sequence in the pair if a pair of
sequences (or a batch of pairs) is provided.
- `'only_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. This will only
truncate the first sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
- `'only_second'`: 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. This will only
truncate the second sequence of a pair if a pair of sequences (or a batch of pairs) is 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.
is_split_into_words (`bool`, *optional*, defaults to `False`):
Whether or not the input is already pre-tokenized (e.g., split into words). If set to `True`, the
tokenizer assumes the input is already split into words (for instance, by splitting it on whitespace)
which it will tokenize. This is useful for NER or token classification.
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).
return_tensors (`str` or [`~utils.TensorType`], *optional*):
If set, will return tensors instead of list of python integers. Acceptable values are:
- `'tf'`: Return TensorFlow `tf.constant` objects.
- `'pt'`: Return PyTorch `torch.Tensor` objects.
- `'np'`: Return Numpy `np.ndarray` objects.

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_offsets_mapping (`bool`, *optional*, defaults to `False`):
Whether or not to return `(char_start, char_end)` for each token.
This is only available on fast tokenizers inheriting from [`PreTrainedTokenizerFast`], if using

'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
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 `huggingface-cli 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.
subfolder (`str`, *optional*):
In case the relevant files are located inside a subfolder of the model repo on huggingface.co (e.g. for
facebook/rag-token-base), specify it here.
inputs (additional positional arguments, *optional*):
Will be passed along to the Tokenizer `__init__` method.
trust_remote_code (`bool`, *optional*, defaults to `False`):
Whether or not to allow for custom models defined on the Hub in their own modeling files. This option
should only be set to `True` for repositories you trust and in which you have read the code, as it will
execute code present on the Hub on your local machine.
kwargs (additional keyword arguments, *optional*):
Will be passed to the Tokenizer `__init__` method. Can be used to set special tokens like `bos_token`,
`eos_token`, `unk_token`, `sep_token`, `pad_token`, `cls_token`, `mask_token`,
`additional_special_tokens`. See parameters in the `__init__` for more details.
<Tip>
Passing `token=True` is required when you want to use a private model.
</Tip>
Examples:
```python
# We can't instantiate directly the base class *PreTrainedTokenizerBase* so let's show our examples on a derived class: BertTokenizer
# Download vocabulary from huggingface.co and cache.
tokenizer = BertTokenizer.from_pretrained("google-bert/bert-base-uncased")
# Download vocabulary from huggingface.co (user-uploaded) and cache.
tokenizer = BertTokenizer.from_pretrained("dbmdz/bert-base-german-cased")
# If vocabulary files are in a directory (e.g. tokenizer was saved using *save_pretrained('./test/saved_model/')*)
tokenizer = BertTokenizer.from_pretrained("./test/saved_model/")
# If the tokenizer uses a single vocabulary file, you can point directly to this file
tokenizer = BertTokenizer.from_pretrained("./test/saved_model/my_vocab.txt")
# You can link tokens to special vocabulary when instantiating
tokenizer = BertTokenizer.from_pretrained("google-bert/bert-base-uncased", unk_token="<unk>")
# You should be sure '<unk>' is in the vocabulary when doing that.
# Otherwise use tokenizer.add_special_tokens({'unk_token': '<unk>'}) instead)
assert tokenizer.unk_token == "<unk>"

If `False`, will only save the tokenizer in the unified JSON format. This format is incompatible with

Pad a single encoded input or a batch of encoded inputs up to predefined length or to the max sequence length
in the batch.
Padding side (left/right) padding token ids are defined at the tokenizer level (with `self.padding_side`,
`self.pad_token_id` and `self.pad_token_type_id`).
Please note that with a fast tokenizer, using the `__call__` method is faster than using a method to encode the
text followed by a call to the `pad` method to get a padded encoding.
<Tip>
If the `encoded_inputs` passed are dictionary of numpy arrays, PyTorch tensors or TensorFlow tensors, the
result will use the same type unless you provide a different tensor type with `return_tensors`. In the case of
PyTorch tensors, you will lose the specific device of your tensors however.
</Tip>
Args:
encoded_inputs ([`BatchEncoding`], list of [`BatchEncoding`], `Dict[str, List[int]]`, `Dict[str, List[List[int]]` or `List[Dict[str, List[int]]]`):
Tokenized inputs. Can represent one input ([`BatchEncoding`] or `Dict[str, List[int]]`) or a batch of
tokenized inputs (list of [`BatchEncoding`], *Dict[str, List[List[int]]]* or *List[Dict[str,
List[int]]]*) so you can use this method during preprocessing as well as in a PyTorch Dataloader
collate function.
Instead of `List[int]` you can have tensors (numpy arrays, PyTorch tensors or TensorFlow tensors), see
the note above for the return type.
padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `True`):
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).
max_length (`int`, *optional*):
Maximum length of the returned list and optionally padding length (see above).
pad_to_multiple_of (`int`, *optional*):
If set will pad the sequence to a multiple of the provided value.
This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability
`>= 7.5` (Volta).
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_tensors (`str` or [`~utils.TensorType`], *optional*):
If set, will return tensors instead of list of python integers. Acceptable values are:
- `'tf'`: Return TensorFlow `tf.constant` objects.
- `'pt'`: Return PyTorch `torch.Tensor` objects.
- `'np'`: Return Numpy `np.ndarray` objects.
verbose (`bool`, *optional*, defaults to `True`):
Whether or not to print more information and warnings.

Arguments:

max_length (`int`, *optional*):
Controls the maximum length for encoder inputs (documents to summarize or source language texts) 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.

Controls the maximum length of decoder inputs (target language texts or summaries) If left unset or set
to `None`, this will use the max_length value.
padding (`bool`, `str` or [`~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 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).
return_tensors (`str` or [`~utils.TensorType`], *optional*):
If set, will return tensors instead of list of python integers. Acceptable values are:
- `'tf'`: Return TensorFlow `tf.constant` objects.
- `'pt'`: Return PyTorch `torch.Tensor` objects.
- `'np'`: Return Numpy `np.ndarray` objects.
truncation (`bool`, `str` or [`~tokenization_utils_base.TruncationStrategy`], *optional*, defaults to `True`):
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. This will
truncate token by token, removing a token from the longest sequence in the pair if a pair of
sequences (or a batch of pairs) is provided.
- `'only_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. This will only
truncate the first sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
- `'only_second'`: 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. This will only
truncate the second sequence of a pair if a pair of sequences (or a batch of pairs) is 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).
**kwargs:
Additional keyword arguments passed along to `self.__call__`.
Return:
[`BatchEncoding`]: A [`BatchEncoding`] with the following fields:
- **input_ids** -- List of token ids to be fed to the encoder.
- **attention_mask** -- List of indices specifying which tokens should be attended to by the model.
- **labels** -- List of token ids for tgt_texts.

Hugging Face was founded in 2016 by French entrepreneurs Clément Delangue, Julien Chaumond, and Thomas Wolf originally as a company that developed a chatbot app targeted at teenagers.[2] After open-sourcing the model behind the chatbot, the company pivoted to focus on being a platform for machine learning.
In March 2021, Hugging Face raised $40 million in a Series B funding round.[3]
On April 28, 2021, the company launched the BigScience Research Workshop in collaboration with several other research groups to release an open large language model.[4] In 2022, the workshop concluded with the announcement of BLOOM, a multilingual large language model with 176 billion parameters.[5]

Utility that performs several consistency checks on the repo. This includes:
- checking all models are properly defined in the __init__ of models/
- checking all models are in the main __init__
- checking all models are properly tested
- checking all object in the main __init__ are documented
- checking all models are in at least one auto class
- checking all the auto mapping are properly defined (no typos, importable)
- checking the list of deprecated models is up to date
Use from the root of the repo with (as used in `make repo-consistency`):
```bash
python utils/check_repo.py

## What is it?
The `trl` library is a full stack tool to fine-tune and align transformer language and diffusion models using methods such as Supervised Fine-tuning step (SFT), Reward Modeling (RM) and the Proximal Policy Optimization (PPO) as well as Direct Preference Optimization (DPO).
The library is built on top of the [`transformers`](https://github.com/huggingface/transformers) library and thus allows to use any model architecture available there.
## Highlights
- **`Efficient and scalable`**:
- [`accelerate`](https://github.com/huggingface/accelerate) is the backbone of `trl` which allows to scale model training from a single GPU to a large scale multi-node cluster with methods such as DDP and DeepSpeed.
- [`PEFT`](https://github.com/huggingface/peft) is fully integrated and allows to train even the largest models on modest hardware with quantisation and methods such as LoRA or QLoRA.
- [`unsloth`](https://github.com/unslothai/unsloth) is also integrated and allows to significantly speed up training with dedicated kernels.
- **`CLI`**: With the [CLI](https://huggingface.co/docs/trl/clis) you can fine-tune and chat with LLMs without writing any code using a single command and a flexible config system.
- **`Trainers`**: The Trainer classes are an abstraction to apply many fine-tuning methods with ease such as the [`SFTTrainer`](https://huggingface.co/docs/trl/sft_trainer), [`DPOTrainer`](https://huggingface.co/docs/trl/trainer#trl.DPOTrainer), [`RewardTrainer`](https://huggingface.co/docs/trl/reward_trainer), and [`PPOTrainer`](https://huggingface.co/docs/trl/trainer#trl.PPOTrainer).
- **`AutoModels`**: The [`AutoModelForCausalLMWithValueHead`](https://huggingface.co/docs/trl/models#trl.AutoModelForCausalLMWithValueHead) & [`AutoModelForSeq2SeqLMWithValueHead`](https://huggingface.co/docs/trl/models#trl.AutoModelForSeq2SeqLMWithValueHead) classes add an additional value head to the model which allows to train them with RL algorithms such as PPO.
- **`Examples`**: Train GPT2 to generate positive movie reviews with a BERT sentiment classifier, full RLHF using adapters only, train GPT-j to be less toxic, [StackLlama example](https://huggingface.co/blog/stackllama), etc. following the [examples](https://github.com/huggingface/trl/tree/main/examples).

## Command Line Interface (CLI)
You can use TRL Command Line Interface (CLI) to quickly get started with Supervised Fine-tuning (SFT), Direct Preference Optimization (DPO) and test your aligned model with the chat CLI:
**SFT:**
```bash
trl sft --model_name_or_path facebook/opt-125m --dataset_name imdb --output_dir opt-sft-imdb
```
**DPO:**
```bash
trl dpo --model_name_or_path facebook/opt-125m --dataset_name trl-internal-testing/hh-rlhf-trl-style --output_dir opt-sft-hh-rlhf
```
**Chat:**
```bash
trl chat --model_name_or_path Qwen/Qwen1.5-0.5B-Chat
```
Read more about CLI in the [relevant documentation section](https://huggingface.co/docs/trl/main/en/clis) or use `--help` for more details.
## How to use
For more flexibility and control over the training you can use the dedicated trainer classes to fine-tune the model in Python.
### `SFTTrainer`
This is a basic example on how to use the `SFTTrainer` from the library. The `SFTTrainer` is a light wrapper around the `transformers` Trainer to easily fine-tune language models or adapters on a custom dataset.
```python
# imports
from datasets import load_dataset
from trl import SFTTrainer
# get dataset
dataset = load_dataset("imdb", split="train")
# get trainer
trainer = SFTTrainer(
"facebook/opt-350m",
train_dataset=dataset,
dataset_text_field="text",
max_seq_length=512,
)
# train
trainer.train()
```
### `RewardTrainer`
This is a basic example on how to use the `RewardTrainer` from the library. The `RewardTrainer` is a wrapper around the `transformers` Trainer to easily fine-tune reward models or adapters on a custom preference dataset.
```python
# imports
from transformers import AutoModelForSequenceClassification, AutoTokenizer
from trl import RewardTrainer
# load model and dataset - dataset needs to be in a specific format
model = AutoModelForSequenceClassification.from_pretrained("gpt2", num_labels=1)
tokenizer = AutoTokenizer.from_pretrained("gpt2")
...
# load trainer
trainer = RewardTrainer(
model=model,
tokenizer=tokenizer,
train_dataset=dataset,
)
# train
trainer.train()
```
### `PPOTrainer`
This is a basic example on how to use the `PPOTrainer` from the library. Based on a query the language model creates a response which is then evaluated. The evaluation could be a human in the loop or another model's output.
```python
# imports
import torch
from transformers import AutoTokenizer
from trl import PPOTrainer, PPOConfig, AutoModelForCausalLMWithValueHead, create_reference_model
from trl.core import respond_to_batch
# get models
model = AutoModelForCausalLMWithValueHead.from_pretrained('gpt2')
model_ref = create_reference_model(model)
tokenizer = AutoTokenizer.from_pretrained('gpt2')
tokenizer.pad_token = tokenizer.eos_token
# initialize trainer
ppo_config = PPOConfig(batch_size=1, mini_batch_size=1)
# encode a query
query_txt = "This morning I went to the "
query_tensor = tokenizer.encode(query_txt, return_tensors="pt")
# get model response
response_tensor = respond_to_batch(model, query_tensor)
# create a ppo trainer
ppo_trainer = PPOTrainer(ppo_config, model, model_ref, tokenizer)
# define a reward for response
# (this could be any reward such as human feedback or output from another model)
reward = [torch.tensor(1.0)]
# train model for one step with ppo
train_stats = ppo_trainer.step([query_tensor[0]], [response_tensor[0]], reward)
```
### `DPOTrainer`
`DPOTrainer` is a trainer that uses [Direct Preference Optimization algorithm](https://arxiv.org/abs/2305.18290). This is a basic example on how to use the `DPOTrainer` from the library. The `DPOTrainer` is a wrapper around the `transformers` Trainer to easily fine-tune reward models or adapters on a custom preference dataset.
```python
# imports
from transformers import AutoModelForCausalLM, AutoTokenizer
from trl import DPOTrainer
# load model and dataset - dataset needs to be in a specific format
model = AutoModelForCausalLM.from_pretrained("gpt2")
tokenizer = AutoTokenizer.from_pretrained("gpt2")
...
# load trainer
trainer = DPOTrainer(
model=model,
tokenizer=tokenizer,
train_dataset=dataset,
)
# train
trainer.train()
```
## Development

# Logging
As reinforcement learning algorithms are historically challenging to debug, it's important to pay careful attention to logging.
By default, the TRL [`PPOTrainer`] saves a lot of relevant information to `wandb` or `tensorboard`.
Upon initialization, pass one of these two options to the [`PPOConfig`]:
```
config = PPOConfig(
model_name=args.model_name,
log_with=`wandb`, # or `tensorboard`
)
```
If you want to log with tensorboard, add the kwarg `project_kwargs={"logging_dir": PATH_TO_LOGS}` to the PPOConfig.
## PPO Logging
Here's a brief explanation for the logged metrics provided in the data:
Key metrics to monitor. We want to maximize the reward, maintain a low KL divergence, and maximize entropy:
1. `env/reward_mean`: The average reward obtained from the environment. Alias `ppo/mean_scores`, which is sed to specifically monitor the reward model.
1. `env/reward_std`: The standard deviation of the reward obtained from the environment. Alias ``ppo/std_scores`, which is sed to specifically monitor the reward model.
1. `env/reward_dist`: The histogram distribution of the reward obtained from the environment.
1. `objective/kl`: The mean Kullback-Leibler (KL) divergence between the old and new policies. It measures how much the new policy deviates from the old policy. The KL divergence is used to compute the KL penalty in the objective function.
1. `objective/kl_dist`: The histogram distribution of the `objective/kl`.
1. `objective/kl_coef`: The coefficient for Kullback-Leibler (KL) divergence in the objective function.
1. `ppo/mean_non_score_reward`: The **KL penalty** calculated by `objective/kl * objective/kl_coef` as the total reward for optimization to prevent the new policy from deviating too far from the old policy.
1. `objective/entropy`: The entropy of the model's policy, calculated by `-logprobs.sum(-1).mean()`. High entropy means the model's actions are more random, which can be beneficial for exploration.
Training stats:
1. `ppo/learning_rate`: The learning rate for the PPO algorithm.
1. `ppo/policy/entropy`: The entropy of the model's policy, calculated by `pd = torch.nn.functional.softmax(logits, dim=-1); entropy = torch.logsumexp(logits, dim=-1) - torch.sum(pd * logits, dim=-1)`. It measures the randomness of the policy.
1. `ppo/policy/clipfrac`: The fraction of probability ratios (old policy / new policy) that fell outside the clipping range in the PPO objective. This can be used to monitor the optimization process.
1. `ppo/policy/approxkl`: The approximate KL divergence between the old and new policies, measured by `0.5 * masked_mean((logprobs - old_logprobs) ** 2, mask)`, corresponding to the `k2` estimator in http://joschu.net/blog/kl-approx.html
1. `ppo/policy/policykl`: Similar to `ppo/policy/approxkl`, but measured by `masked_mean(old_logprobs - logprobs, mask)`, corresponding to the `k1` estimator in http://joschu.net/blog/kl-approx.html
1. `ppo/policy/ratio`: The histogram distribution of the ratio between the new and old policies, used to compute the PPO objective.
1. `ppo/policy/advantages_mean`: The average of the GAE (Generalized Advantage Estimation) advantage estimates. The advantage function measures how much better an action is compared to the average action at a state.
1. `ppo/policy/advantages`: The histogram distribution of `ppo/policy/advantages_mean`.
1. `ppo/returns/mean`: The mean of the TD(λ) returns, calculated by `returns = advantage + values`, another indicator of model performance. See https://iclr-blog-track.github.io/2022/03/25/ppo-implementation-details/ for more details.
1. `ppo/returns/var`: The variance of the TD(λ) returns, calculated by `returns = advantage + values`, another indicator of model performance.
1. `ppo/val/mean`: The mean of the values, used to monitor the value function's performance.
1. `ppo/val/var` : The variance of the values, used to monitor the value function's performance.
1. `ppo/val/var_explained`: The explained variance for the value function, used to monitor the value function's performance.
1. `ppo/val/clipfrac`: The fraction of the value function's predicted values that are clipped.
1. `ppo/val/vpred`: The predicted values from the value function.
1. `ppo/val/error`: The mean squared error between the `ppo/val/vpred` and returns, used to monitor the value function's performance.
1. `ppo/loss/policy`: The policy loss for the Proximal Policy Optimization (PPO) algorithm.
1. `ppo/loss/value`: The loss for the value function in the PPO algorithm. This value quantifies how well the function estimates the expected future rewards.
1. `ppo/loss/total`: The total loss for the PPO algorithm. It is the sum of the policy loss and the value function loss.
Stats on queries, responses, and logprobs:
1. `tokens/queries_len_mean`: The average length of the queries tokens.
1. `tokens/queries_len_std`: The standard deviation of the length of the queries tokens.
1. `tokens/queries_dist`: The histogram distribution of the length of the queries tokens.
1. `tokens/responses_len_mean`: The average length of the responses tokens.
1. `tokens/responses_len_std`: The standard deviation of the length of the responses tokens.
1. `tokens/responses_dist`: The histogram distribution of the length of the responses tokens. (Costa: inconsistent naming, should be `tokens/responses_len_dist`)
1. `objective/logprobs`: The histogram distribution of the log probabilities of the actions taken by the model.
1. `objective/ref_logprobs`: The histogram distribution of the log probabilities of the actions taken by the reference model.
### Crucial values
During training, many values are logged, here are the most important ones:
1. `env/reward_mean`,`env/reward_std`, `env/reward_dist`: the properties of the reward distribution from the "environment" / reward model
1. `ppo/mean_non_score_reward`: The mean negated KL penalty during training (shows the delta between the reference model and the new policy over the batch in the step)
Here are some parameters that are useful to monitor for stability (when these diverge or collapse to 0, try tuning variables):
1. `ppo/loss/value`: it will spike / NaN when not going well.
1. `ppo/policy/ratio`: `ratio` being 1 is a baseline value, meaning that the probability of sampling a token is the same under the new and old policy. If the ratio is too high like 200, it means the probability of sampling a token is 200 times higher under the new policy than the old policy. This is a sign that the new policy is too different from the old policy, which will likely cause overoptimization and collapse training later on.
1. `ppo/policy/clipfrac` and `ppo/policy/approxkl`: if `ratio` is too high, the `ratio` is going to get clipped, resulting in high `clipfrac` and high `approxkl` as well.
1. `objective/kl`: it should stay positive so that the policy is not too far away from the reference policy.
1. `objective/kl_coef`: The target coefficient with [`AdaptiveKLController`]. Often increases before numerical instabilities. | trl/docs/source/logging.mdx/0 | {

# Launching Multi-GPU Training from a Jupyter Environment
This tutorial teaches you how to fine tune a computer vision model with 🤗 Accelerate from a Jupyter Notebook on a distributed system.
You will also learn how to setup a few requirements needed for ensuring your environment is configured properly, your data has been prepared properly, and finally how to launch training.
<Tip>
This tutorial is also available as a Jupyter Notebook [here](https://github.com/huggingface/notebooks/blob/main/examples/accelerate_examples/simple_cv_example.ipynb)
</Tip>
## Configuring the Environment
Before any training can be performed, a 🤗 Accelerate config file must exist in the system. Usually this can be done by running the following in a terminal and answering the prompts:
```bash
accelerate config
```
However, if general defaults are fine and you are *not* running on a TPU, 🤗Accelerate has a utility to quickly write your GPU configuration into a config file via [`utils.write_basic_config`].
The following code will restart Jupyter after writing the configuration, as CUDA code was called to perform this.
<Tip warning={true}>
CUDA can't be initialized more than once on a multi-GPU system. It's fine to debug in the notebook and have calls to CUDA, but in order to finally train a full cleanup and restart will need to be performed.
</Tip>
```python
import os
from accelerate.utils import write_basic_config
write_basic_config() # Write a config file
os._exit(00) # Restart the notebook
```
## Preparing the Dataset and Model
Next you should prepare your dataset. As mentioned at earlier, great care should be taken when preparing the `DataLoaders` and model to make sure that **nothing** is put on *any* GPU.
If you do, it is recommended to put that specific code into a function and call that from within the notebook launcher interface, which will be shown later.
Make sure the dataset is downloaded based on the directions [here](https://github.com/huggingface/accelerate/tree/main/examples#simple-vision-example)
```python
import os, re, torch, PIL
import numpy as np
from torch.optim.lr_scheduler import OneCycleLR
from torch.utils.data import DataLoader, Dataset
from torchvision.transforms import Compose, RandomResizedCrop, Resize, ToTensor
from accelerate import Accelerator
from accelerate.utils import set_seed
from timm import create_model
```
First you need to create a function to extract the class name based on a filename:
```python
import os
data_dir = "../../images"
fnames = os.listdir(data_dir)
fname = fnames[0]
print(fname)
```
```python out
beagle_32.jpg
```
In the case here, the label is `beagle`. Using regex you can extract the label from the filename:
```python
import re
def extract_label(fname):
stem = fname.split(os.path.sep)[-1]
return re.search(r"^(.*)_\d+\.jpg$", stem).groups()[0]
```
```python
extract_label(fname)
```
And you can see it properly returned the right name for our file:
```python out
"beagle"
```
Next a `Dataset` class should be made to handle grabbing the image and the label:
```python
class PetsDataset(Dataset):
def __init__(self, file_names, image_transform=None, label_to_id=None):
self.file_names = file_names
self.image_transform = image_transform
self.label_to_id = label_to_id
def __len__(self):
return len(self.file_names)
def __getitem__(self, idx):
fname = self.file_names[idx]
raw_image = PIL.Image.open(fname)
image = raw_image.convert("RGB")
if self.image_transform is not None:
image = self.image_transform(image)
label = extract_label(fname)
if self.label_to_id is not None:
label = self.label_to_id[label]
return {"image": image, "label": label}
```
Now to build the dataset. Outside the training function you can find and declare all the filenames and labels and use them as references inside the
launched function:
```python
fnames = [os.path.join("../../images", fname) for fname in fnames if fname.endswith(".jpg")]
```
Next gather all the labels:
```python
all_labels = [extract_label(fname) for fname in fnames]
id_to_label = list(set(all_labels))
id_to_label.sort()
label_to_id = {lbl: i for i, lbl in enumerate(id_to_label)}
```
Next, you should make a `get_dataloaders` function that will return your built dataloaders for you. As mentioned earlier, if data is automatically
sent to the GPU or a TPU device when building your `DataLoaders`, they must be built using this method.
```python
def get_dataloaders(batch_size: int = 64):
"Builds a set of dataloaders with a batch_size"
random_perm = np.random.permutation(len(fnames))
cut = int(0.8 * len(fnames))
train_split = random_perm[:cut]
eval_split = random_perm[cut:]
# For training a simple RandomResizedCrop will be used
train_tfm = Compose([RandomResizedCrop((224, 224), scale=(0.5, 1.0)), ToTensor()])
train_dataset = PetsDataset([fnames[i] for i in train_split], image_transform=train_tfm, label_to_id=label_to_id)
# For evaluation a deterministic Resize will be used
eval_tfm = Compose([Resize((224, 224)), ToTensor()])
eval_dataset = PetsDataset([fnames[i] for i in eval_split], image_transform=eval_tfm, label_to_id=label_to_id)
# Instantiate dataloaders
train_dataloader = DataLoader(train_dataset, shuffle=True, batch_size=batch_size, num_workers=4)
eval_dataloader = DataLoader(eval_dataset, shuffle=False, batch_size=batch_size * 2, num_workers=4)
return train_dataloader, eval_dataloader
```
Finally, you should import the scheduler to be used later:
```python
from torch.optim.lr_scheduler import CosineAnnealingLR
```
## Writing the Training Function
Now you can build the training loop. [`notebook_launcher`] works by passing in a function to call that will be ran across the distributed system.
Here is a basic training loop for the animal classification problem:
<Tip>
The code has been split up to allow for explanations on each section. A full version that can be copy and pasted will be available at the end
</Tip>
```python
def training_loop(mixed_precision="fp16", seed: int = 42, batch_size: int = 64):
set_seed(seed)
accelerator = Accelerator(mixed_precision=mixed_precision)
```
First you should set the seed and create an [`Accelerator`] object as early in the training loop as possible.
<Tip warning={true}>
If training on the TPU, your training loop should take in the model as a parameter and it should be instantiated
outside of the training loop function. See the [TPU best practices](../concept_guides/training_tpu)
to learn why
</Tip>
Next you should build your dataloaders and create your model:
```python
train_dataloader, eval_dataloader = get_dataloaders(batch_size)
model = create_model("resnet50d", pretrained=True, num_classes=len(label_to_id))
```
<Tip>
You build the model here so that the seed also controls the new weight initialization
</Tip>
As you are performing transfer learning in this example, the encoder of the model starts out frozen so the head of the model can be
trained only initially:
```python
for param in model.parameters():
param.requires_grad = False
for param in model.get_classifier().parameters():
param.requires_grad = True
```
Normalizing the batches of images will make training a little faster:
```python
mean = torch.tensor(model.default_cfg["mean"])[None, :, None, None]
std = torch.tensor(model.default_cfg["std"])[None, :, None, None]
```
To make these constants available on the active device, you should set it to the Accelerator's device:
```python
mean = mean.to(accelerator.device)
std = std.to(accelerator.device)
```
Next instantiate the rest of the PyTorch classes used for training:
```python
optimizer = torch.optim.Adam(params=model.parameters(), lr=3e-2 / 25)
lr_scheduler = OneCycleLR(optimizer=optimizer, max_lr=3e-2, epochs=5, steps_per_epoch=len(train_dataloader))
```
Before passing everything to [`~Accelerator.prepare`].
<Tip>
There is no specific order to remember, you just need to unpack the objects in the same order you gave them to the prepare method.
</Tip>
```python
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler = accelerator.prepare(
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler
)
```
Now train the model:
```python
for epoch in range(5):
model.train()
for batch in train_dataloader:
inputs = (batch["image"] - mean) / std
outputs = model(inputs)
loss = torch.nn.functional.cross_entropy(outputs, batch["label"])
accelerator.backward(loss)
optimizer.step()
lr_scheduler.step()
optimizer.zero_grad()
```
The evaluation loop will look slightly different compared to the training loop. The number of elements passed as well as the overall
total accuracy of each batch will be added to two constants:
```python
model.eval()
accurate = 0
num_elems = 0
```
Next you have the rest of your standard PyTorch loop:
```python
for batch in eval_dataloader:
inputs = (batch["image"] - mean) / std
with torch.no_grad():
outputs = model(inputs)
predictions = outputs.argmax(dim=-1)
```
Before finally the last major difference.
When performing distributed evaluation, the predictions and labels need to be passed through
[`~Accelerator.gather`] so that all of the data is available on the current device and a properly calculated metric can be achieved:
```python
accurate_preds = accelerator.gather(predictions) == accelerator.gather(batch["label"])
num_elems += accurate_preds.shape[0]
accurate += accurate_preds.long().sum()
```
Now you just need to calculate the actual metric for this problem, and you can print it on the main process using [`~Accelerator.print`]:
```python
eval_metric = accurate.item() / num_elems
accelerator.print(f"epoch {epoch}: {100 * eval_metric:.2f}")
```
A full version of this training loop is available below:
```python
def training_loop(mixed_precision="fp16", seed: int = 42, batch_size: int = 64):
set_seed(seed)
# Initialize accelerator
accelerator = Accelerator(mixed_precision=mixed_precision)
# Build dataloaders
train_dataloader, eval_dataloader = get_dataloaders(batch_size)
# Instantiate the model (you build the model here so that the seed also controls new weight initaliziations)
model = create_model("resnet50d", pretrained=True, num_classes=len(label_to_id))
# Freeze the base model
for param in model.parameters():
param.requires_grad = False
for param in model.get_classifier().parameters():
param.requires_grad = True
# You can normalize the batches of images to be a bit faster
mean = torch.tensor(model.default_cfg["mean"])[None, :, None, None]
std = torch.tensor(model.default_cfg["std"])[None, :, None, None]
# To make these constants available on the active device, set it to the accelerator device
mean = mean.to(accelerator.device)
std = std.to(accelerator.device)
# Instantiate the optimizer
optimizer = torch.optim.Adam(params=model.parameters(), lr=3e-2 / 25)
# Instantiate the learning rate scheduler
lr_scheduler = OneCycleLR(optimizer=optimizer, max_lr=3e-2, epochs=5, steps_per_epoch=len(train_dataloader))
# Prepare everything
# There is no specific order to remember, you just need to unpack the objects in the same order you gave them to the
# prepare method.
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler = accelerator.prepare(
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler
)
# Now you train the model
for epoch in range(5):
model.train()
for batch in train_dataloader:
inputs = (batch["image"] - mean) / std
outputs = model(inputs)
loss = torch.nn.functional.cross_entropy(outputs, batch["label"])
accelerator.backward(loss)
optimizer.step()
lr_scheduler.step()
optimizer.zero_grad()
model.eval()
accurate = 0
num_elems = 0
for batch in eval_dataloader:
inputs = (batch["image"] - mean) / std
with torch.no_grad():
outputs = model(inputs)
predictions = outputs.argmax(dim=-1)
accurate_preds = accelerator.gather(predictions) == accelerator.gather(batch["label"])
num_elems += accurate_preds.shape[0]
accurate += accurate_preds.long().sum()
eval_metric = accurate.item() / num_elems
# Use accelerator.print to print only on the main process.
accelerator.print(f"epoch {epoch}: {100 * eval_metric:.2f}")
```

All that's left is to use the [`notebook_launcher`].
You pass in the function, the arguments (as a tuple), and the number of processes to train on. (See the [documentation](../package_reference/launchers) for more information)
```python
from accelerate import notebook_launcher
```
```python
args = ("fp16", 42, 64)
notebook_launcher(training_loop, args, num_processes=2)
```
In the case of running on multiple nodes, you need to set up a Jupyter session at each node and run the launching cell at the same time.
For an environment containing 2 nodes (computers) with 8 GPUs each and the main computer with an IP address of "172.31.43.8", it would look like so:
```python
notebook_launcher(training_loop, args, master_addr="172.31.43.8", node_rank=0, num_nodes=2, num_processes=8)
```
And in the second Jupyter session on the other machine:
<Tip>
Notice how the `node_rank` has changed
</Tip>
```python
notebook_launcher(training_loop, args, master_addr="172.31.43.8", node_rank=1, num_nodes=2, num_processes=8)
```
In the case of running on the TPU, it would look like so:
```python
model = create_model("resnet50d", pretrained=True, num_classes=len(label_to_id))
args = (model, "fp16", 42, 64)
notebook_launcher(training_loop, args, num_processes=8)
```
As it's running it will print the progress as well as state how many devices you ran on. This tutorial was ran with two GPUs:
```python out
Launching training on 2 GPUs.
epoch 0: 88.12
epoch 1: 91.73
epoch 2: 92.58
epoch 3: 93.90
epoch 4: 94.71
```
And that's it!
## Debugging
A common issue when running the `notebook_launcher` is receiving a CUDA has already been initialized issue. This usually stems
from an import or prior code in the notebook that makes a call to the PyTorch `torch.cuda` sublibrary. To help narrow down what went wrong,
you can launch the `notebook_launcher` with `ACCELERATE_DEBUG_MODE=yes` in your environment and an additional check
will be made when spawning that a regular process can be created and utilize CUDA without issue. (Your CUDA code can still be ran afterwards).
## Conclusion
This notebook showed how to perform distributed training from inside of a Jupyter Notebook. Some key notes to remember:
- Make sure to save any code that use CUDA (or CUDA imports) for the function passed to [`notebook_launcher`]
- Set the `num_processes` to be the number of devices used for training (such as number of GPUs, CPUs, TPUs, etc)
- If using the TPU, declare your model outside the training loop function

# Distributed Inference with 🤗 Accelerate
Distributed inference can fall into three brackets:
1. Loading an entire model onto each GPU and sending chunks of a batch through each GPU's model copy at a time
2. Loading parts of a model onto each GPU and processing a single input at one time
3. Loading parts of a model onto each GPU and using what is called scheduled Pipeline Parallelism to combine the two prior techniques.
We're going to go through the first and the last bracket, showcasing how to do each as they are more realistic scenarios.
## Sending chunks of a batch automatically to each loaded model
This is the most memory-intensive solution, as it requires each GPU to keep a full copy of the model in memory at a given time.
Normally when doing this, users send the model to a specific device to load it from the CPU, and then move each prompt to a different device.
A basic pipeline using the `diffusers` library might look something like so:
```python
import torch
import torch.distributed as dist
from diffusers import DiffusionPipeline
pipe = DiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16)
```
Followed then by performing inference based on the specific prompt:
```python
def run_inference(rank, world_size):
dist.init_process_group("nccl", rank=rank, world_size=world_size)
pipe.to(rank)
if torch.distributed.get_rank() == 0:
prompt = "a dog"
elif torch.distributed.get_rank() == 1:
prompt = "a cat"
result = pipe(prompt).images[0]
result.save(f"result_{rank}.png")
```
One will notice how we have to check the rank to know what prompt to send, which can be a bit tedious.
A user might then also think that with 🤗 Accelerate, using the `Accelerator` to prepare a dataloader for such a task might also be
a simple way to manage this. (To learn more, check out the relevant section in the [Quick Tour](../quicktour#distributed-evaluation))
Can it manage it? Yes. Does it add unneeded extra code however: also yes.
With 🤗 Accelerate, we can simplify this process by using the [`Accelerator.split_between_processes`] context manager (which also exists in `PartialState` and `AcceleratorState`).
This function will automatically split whatever data you pass to it (be it a prompt, a set of tensors, a dictionary of the prior data, etc.) across all the processes (with a potential
to be padded) for you to use right away.
Let's rewrite the above example using this context manager:
```python
from accelerate import PartialState # Can also be Accelerator or AcceleratorState
from diffusers import DiffusionPipeline
pipe = DiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16)
distributed_state = PartialState()
pipe.to(distributed_state.device)
# Assume two processes
with distributed_state.split_between_processes(["a dog", "a cat"]) as prompt:
result = pipe(prompt).images[0]
result.save(f"result_{distributed_state.process_index}.png")
```
And then to launch the code, we can use the 🤗 Accelerate:
If you have generated a config file to be used using `accelerate config`:
```bash
accelerate launch distributed_inference.py
```
If you have a specific config file you want to use:
```bash
accelerate launch --config_file my_config.json distributed_inference.py
```
Or if don't want to make any config files and launch on two GPUs:
> Note: You will get some warnings about values being guessed based on your system. To remove these you can do `accelerate config default` or go through `accelerate config` to create a config file.
```bash
accelerate launch --num_processes 2 distributed_inference.py
```
We've now reduced the boilerplate code needed to split this data to a few lines of code quite easily.
But what if we have an odd distribution of prompts to GPUs? For example, what if we have 3 prompts, but only 2 GPUs?
Under the context manager, the first GPU would receive the first two prompts and the second GPU the third, ensuring that
all prompts are split and no overhead is needed.
*However*, what if we then wanted to do something with the results of *all the GPUs*? (Say gather them all and perform some kind of post processing)
You can pass in `apply_padding=True` to ensure that the lists of prompts are padded to the same length, with extra data being taken
from the last sample. This way all GPUs will have the same number of prompts, and you can then gather the results.
<Tip>
This is only needed when trying to perform an action such as gathering the results, where the data on each device
needs to be the same length. Basic inference does not require this.
</Tip>
For instance:
```python
from accelerate import PartialState # Can also be Accelerator or AcceleratorState
from diffusers import DiffusionPipeline
pipe = DiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16)
distributed_state = PartialState()
pipe.to(distributed_state.device)
# Assume two processes
with distributed_state.split_between_processes(["a dog", "a cat", "a chicken"], apply_padding=True) as prompt:
result = pipe(prompt).images
```
On the first GPU, the prompts will be `["a dog", "a cat"]`, and on the second GPU it will be `["a chicken", "a chicken"]`.
Make sure to drop the final sample, as it will be a duplicate of the previous one.
## Memory-efficient pipeline parallelism (experimental)
This next part will discuss using *pipeline parallelism*. This is an **experimental** API utilizing the [PiPPy library by PyTorch](https://github.com/pytorch/PiPPy/) as a native solution.
The general idea with pipeline parallelism is: say you have 4 GPUs and a model big enough it can be *split* on four GPUs using `device_map="auto"`. With this method you can send in 4 inputs at a time (for example here, any amount works) and each model chunk will work on an input, then receive the next input once the prior chunk finished, making it *much* more efficient **and faster** than the method described earlier. Here's a visual taken from the PyTorch repository:
To illustrate how you can use this with Accelerate, we have created an [example zoo](https://github.com/huggingface/accelerate/tree/main/examples/inference) showcasing a number of different models and situations. In this tutorial, we'll show this method for GPT2 across two GPUs.
Before you proceed, please make sure you have the latest pippy installed by running the following:
```bash
pip install torchpippy
```
We require at least version 0.2.0. To confirm that you have the correct version, run `pip show torchpippy`.
Start by creating the model on the CPU:
```{python}
from transformers import GPT2ForSequenceClassification, GPT2Config
config = GPT2Config()
model = GPT2ForSequenceClassification(config)
model.eval()
```
Next you'll need to create some example inputs to use. These help PiPPy trace the model.
<Tip warning={true}>
However you make this example will determine the relative batch size that will be used/passed
through the model at a given time, so make sure to remember how many items there are!
</Tip>
```{python}
input = torch.randint(
low=0,
high=config.vocab_size,
size=(2, 1024), # bs x seq_len
device="cpu",
dtype=torch.int64,
requires_grad=False,
)
```
Next we need to actually perform the tracing and get the model ready. To do so, use the [`inference.prepare_pippy`] function and it will fully wrap the model for pipeline parallelism automatically:
```{python}
from accelerate.inference import prepare_pippy
example_inputs = {"input_ids": input}
model = prepare_pippy(model, example_args=(input,))
```
<Tip>
There are a variety of parameters you can pass through to `prepare_pippy`:
* `split_points` lets you determine what layers to split the model at. By default we use wherever `device_map="auto" declares, such as `fc` or `conv1`.
* `num_chunks` determines how the batch will be split and sent to the model itself (so `num_chunks=1` with four split points/four GPUs will have a naive MP where a single input gets passed between the four layer split points)
</Tip>
From here, all that's left is to actually perform the distributed inference!
<Tip warning={true}>
When passing inputs, we highly recommend to pass them in as a tuple of arguments. Using `kwargs` is supported, however, this approach is experimental.
</Tip>
```{python}
args = some_more_arguments
with torch.no_grad():
output = model(*args)
```
When finished all the data will be on the last process only:
```{python}
from accelerate import PartialState
if PartialState().is_last_process:
print(output)
```
<Tip>
If you pass in `gather_output=True` to [`inference.prepare_pippy`], the output will be sent
across to all the GPUs afterwards without needing the `is_last_process` check. This is
`False` by default as it incurs a communication call.
</Tip>
And that's it! To explore more, please check out the inference examples in the [Accelerate repo](https://github.com/huggingface/accelerate/tree/main/examples/inference) and our [documentation](../package_reference/inference) as we work to improving this integration.

########################################################################
# This is a fully working simple example to use Accelerate,
# specifically showcasing how to combine both the gradient accumulation
# and automatic batch size finder utilities of Accelerate to perfrom
# automatic gradient accumulation
#
# This example trains a Bert base model on GLUE MRPC
# in any of the following settings (with the same script):
# - single CPU or single GPU
# - multi GPUS (using PyTorch distributed mode)
# - (multi) TPUs
# - fp16 (mixed-precision) or fp32 (normal precision)
#
# New additions from the base script can be found quickly by
# looking for the # New Code # tags
#
# To run it in each of these various modes, follow the instructions
# in the readme for examples:
# https://github.com/huggingface/accelerate/tree/main/examples

Args:
dataloader (`torch.utils.data.dataloader.DataLoader`):
The data loader to split across several devices.

The target device for the returned `DataLoader`.
num_processes (`int`, *optional*):

put_on_device (`bool`, *optional*, defaults to `False`):
Whether or not to put the batches on `device` (only works if the batches are nested list, tuples or
dictionaries of tensors).
rng_types (list of `str` or [`~utils.RNGType`]):
The list of random number generators to synchronize at the beginning of each iteration. Should be one or
several of:
- `"torch"`: the base torch random number generator
- `"cuda"`: the CUDA random number generator (GPU only)
- `"xla"`: the XLA random number generator (TPU only)
- `"generator"`: the `torch.Generator` of the sampler (or batch sampler if there is no sampler in your
dataloader) or of the iterable dataset (if it exists) if the underlying dataset is of that type.
dispatch_batches (`bool`, *optional*):
If set to `True`, the datalaoder prepared is only iterated through on the main process and then the batches
are split and broadcast to each process. Will default to `True` when the underlying dataset is an
`IterableDataset`, `False` otherwise.
even_batches (`bool`, *optional*, defaults to `True`):
If set to `True`, in cases where the total batch size across all processes does not exactly divide the
dataset, samples at the start of the dataset will be duplicated so the batch can be divided equally among
all workers.
slice_fn_for_dispatch (`Callable`, *optional*`):
If passed, this function will be used to slice tensors across `num_processes`. Will default to
[`~utils.slice_tensors`]. This argument is used only when `dispatch_batches` is set to `True` and will be
ignored otherwise.
use_seedable_sampler (`bool`, *optional*, defaults to `False`):
Whether to use the [`~data_loader.SeedableRandomSampler`] instead of a `RandomSampler` for better
reproducability. Comes at a cost of potentially different performances due to different shuffling
algorithms but ensures results will be the *exact* same. Should be paired with `set_seed()` at every

# MNIST
So we now have downloaded the MNIST parquet files, let's put them in a simple struct.
```rust,ignore
{{#include ../lib.rs:book_training_3}}
```
The parsing of the file and putting it into single tensors requires the dataset to fit the entire memory.
It is quite rudimentary, but simple enough for a small dataset like MNIST.

# candle-quantized-llama: Fast Inference of quantized LLaMA models
This example provides a quantized LLaMA model similar to
[llama.cpp](https://github.com/ggerganov/llama.cpp). This is based on candle
built-in quantization methods. Supported features include:
- 2-bit, 3-bit, 4-bit, 5-bit, 6-bit and 8-bit integer quantization support.
- SIMD optimizations on Apple Silicon and x86.
- Support using the `gguf` and `ggml` file formats.
The weights are automatically downloaded for you from the [HuggingFace
Hub](https://huggingface.co/) on the first run. There are various command line
flags to use local files instead, run with `--help` to learn about them.
## Running some example.
```bash
cargo run --example quantized --release -- --prompt "The best thing about coding in rust is "
> avx: true, neon: false, simd128: false, f16c: true
> temp: 0.80 repeat-penalty: 1.10 repeat-last-n: 64
> loaded 291 tensors (3.79GB) in 2.17s
> params: HParams { n_vocab: 32000, n_embd: 4096, n_mult: 256, n_head: 32, n_layer: 32, n_rot: 128, ftype: 2 }
> The best thing about coding in rust is 1.) that I don’t need to worry about memory leaks, 2.) speed and 3.) my program will compile even on old machines.
```
Using the mixtral sparse mixture of expert model:
```bash
$ cargo run --example quantized --release -- --which mixtral --prompt "Lebesgue's integral is superior to Riemann's because "
> avx: true, neon: false, simd128: false, f16c: true
> temp: 0.80 repeat-penalty: 1.10 repeat-last-n: 64
> loaded 995 tensors (26.44GB) in 0.03s
Lebesgue's integral is superior to Riemann's because 1. it is defined for a wider class of functions, those which are absolutely integrable; 2. the definition does not involve limits in two variables---one being computed before the other (which makes some computations more difficult); and 3. interchange of order of integration is easier to establish than with Riemann's integral. On the other hand, Lebesgue's integral applies only for bounded functions defined on finite intervals; it does not provide numerical values for improper integrals. The latter are best evaluated using Cauchy's limit definition.
The reason $f(x) = x^2$ is discontinuous at the ends of its interval of definition, and Riemann's integral requires continuity on the whole of an open interval containing it (see our earlier post), sine no such function exists with this property, is that the endpoints are infinite in measure for Lebesgue's integral.
```
## Command-line flags
Run with `--help` to see all options.
- `--which`: specify the model to use, e.g. `7b`, `13-chat`, `7b-code`.
- `--prompt interactive`: interactive mode where multiple prompts can be
entered.
- `--model mymodelfile.gguf`: use a local model file rather than getting one
from the hub.

# candle-stable-lm
StableLM-3B-4E1T is a 3 billion parameter decoder-only language model
pre-trained on 1 trillion tokens of diverse English and code datasets for 4
epochs. See the [HuggingFace Hub Model
Card](https://huggingface.co/stabilityai/stablelm-3b-4e1t).
Note that this model is gated so you will have to request access on the Hub in
order to be able to use it.
Other available models are Stable-Code-3B, StableLM-2 and Zephyr variants.
## Running some example
```bash
$ cargo run --example stable-lm --release --features cuda -- --prompt 'What is the most efficient programming language in use?' --sample-len 150
avx: true, neon: false, simd128: false, f16c: true
temp: 0.00 repeat-penalty: 1.10 repeat-last-n: 64
retrieved the files in 126.593µs
loaded the model in 3.474148965s
What is the most efficient programming language in use?
The answer to this question depends on what you mean by "efficient". If you're talking about speed, then C++ and Java are probably your best bets. But if you're talking about ease of development, then Python is probably the way to go.
Python is a high-level, interpreted language that is easy to learn and use. It has a large community of developers who are always working on new features and improvements.
C++ is a low-level, compiled language that can be used for both desktop applications and web development. It's more difficult to learn than Python but offers greater control over the code.
Java is another high-level language that is popular with programmers because it runs on many different platforms (including Android phones

# candle-whisper: speech recognition
An implementation of [OpenAI Whisper](https://github.com/openai/whisper) using
candle. Whisper is a general purpose speech recognition model, it can be used to
convert audio files (in the `.wav` format) to text. Supported features include
language detection as well as multilingual speech recognition.
## Running some example
If no audio file is passed as input, a [sample
file](https://huggingface.co/datasets/Narsil/candle-examples/resolve/main/samples_jfk.wav) is automatically downloaded
from the hub.
```bash
cargo run --example whisper --release
> No audio file submitted: Downloading https://huggingface.co/datasets/Narsil/candle_demo/blob/main/samples_jfk.wav
> loaded wav data: Header { audio_format: 1, channel_count: 1, sampling_rate: 16000, bytes_per_second: 32000, bytes_per_sample: 2, bits_per_sample: 16 }
> pcm data loaded 176000
> loaded mel: [1, 80, 3000]
> 0.0s -- 30.0s: And so my fellow Americans ask not what your country can do for you ask what you can do for your country
```
In order to use the multilingual mode, specify a multilingual model via the
`--model` flag, see the details below.
## Command line flags
- `--input`: the audio file to be converted to text, in wav format.
- `--language`: force the language to some specific value rather than being
detected, e.g. `en`.
- `--task`: the task to be performed, can be `transcribe` (return the text data
in the original language) or `translate` (translate the text to English).
- `--timestamps`: enable the timestamp mode where some timestamps are reported
for each recognized audio extracts.
- `--model`: the model to be used. Models that do not end with `-en` are
multilingual models, other ones are English only models. The supported models
are `tiny`, `tiny.en`, `base`, `base.en`, `small`, `small.en`, `medium`,
`medium.en`, `large`, and `large-v2`.
