# Pipelines

The pipelines are a great and easy way to use models for inference. These pipelines are objects that abstract most of
the complex code from the library, offering a simple API dedicated to several tasks, including Named Entity
Recognition, Masked Language Modeling, Sentiment Analysis, Feature Extraction and Question Answering. See the
[task summary](../task_summary) for examples of use.

There are two categories of pipeline abstractions to be aware about:

- The [pipeline()](/docs/transformers/v5.0.0rc1/en/main_classes/pipelines#transformers.pipeline) which is the most powerful object encapsulating all other pipelines.
- Task-specific pipelines are available for [audio](#audio), [computer vision](#computer-vision), [natural language processing](#natural-language-processing), and [multimodal](#multimodal) tasks.

## The pipeline abstraction[[transformers.pipeline]]

The *pipeline* abstraction is a wrapper around all the other available pipelines. It is instantiated as any other
pipeline but can provide additional quality of life.

Simple call on one item:

```python
>>> pipe = pipeline("text-classification")
>>> pipe("This restaurant is awesome")
[{'label': 'POSITIVE', 'score': 0.9998743534088135}]
```

If you want to use a specific model from the [hub](https://huggingface.co) you can ignore the task if the model on
the hub already defines it:

```python
>>> pipe = pipeline(model="FacebookAI/roberta-large-mnli")
>>> pipe("This restaurant is awesome")
[{'label': 'NEUTRAL', 'score': 0.7313136458396912}]
```

To call a pipeline on many items, you can call it with a *list*.

```python
>>> pipe = pipeline("text-classification")
>>> pipe(["This restaurant is awesome", "This restaurant is awful"])
[{'label': 'POSITIVE', 'score': 0.9998743534088135},
 {'label': 'NEGATIVE', 'score': 0.9996669292449951}]
```

To iterate over full datasets it is recommended to use a `dataset` directly. This means you don't need to allocate
the whole dataset at once, nor do you need to do batching yourself. This should work just as fast as custom loops on
GPU. If it doesn't don't hesitate to create an issue.

```python
import datasets
from transformers import pipeline
from transformers.pipelines.pt_utils import KeyDataset
from tqdm.auto import tqdm

pipe = pipeline("automatic-speech-recognition", model="facebook/wav2vec2-base-960h", device=0)
dataset = datasets.load_dataset("superb", name="asr", split="test")

# KeyDataset (only *pt*) will simply return the item in the dict returned by the dataset item
# as we're not interested in the *target* part of the dataset. For sentence pair use KeyPairDataset
for out in tqdm(pipe(KeyDataset(dataset, "file"))):
    print(out)
    # {"text": "NUMBER TEN FRESH NELLY IS WAITING ON YOU GOOD NIGHT HUSBAND"}
    # {"text": ....}
    # ....
```

For ease of use, a generator is also possible:

```python
from transformers import pipeline

pipe = pipeline("text-classification")

def data():
    while True:
        # This could come from a dataset, a database, a queue or HTTP request
        # in a server
        # Caveat: because this is iterative, you cannot use `num_workers > 1` variable
        # to use multiple threads to preprocess data. You can still have 1 thread that
        # does the preprocessing while the main runs the big inference
        yield "This is a test"

for out in pipe(data()):
    print(out)
    # {"text": "NUMBER TEN FRESH NELLY IS WAITING ON YOU GOOD NIGHT HUSBAND"}
    # {"text": ....}
    # ....
```

Utility factory method to build a [Pipeline](/docs/transformers/v5.0.0rc1/en/main_classes/pipelines#transformers.Pipeline).

A pipeline consists of:

- One or more components for pre-processing model inputs, such as a [tokenizer](tokenizer),
[image_processor](image_processor), [feature_extractor](feature_extractor), or [processor](processors).
- A [model](model) that generates predictions from the inputs.
- Optional post-processing steps to refine the model's output, which can also be handled by processors.

While there are such optional arguments as `tokenizer`, `feature_extractor`, `image_processor`, and `processor`,
they shouldn't be specified all at once. If these components are not provided, `pipeline` will try to load
required ones automatically. In case you want to provide these components explicitly, please refer to a
specific pipeline in order to get more details regarding what components are required.

Examples:

```python
>>> from transformers import pipeline, AutoModelForTokenClassification, AutoTokenizer

>>> # Sentiment analysis pipeline
>>> analyzer = pipeline("sentiment-analysis")

>>> # Question answering pipeline, specifying the checkpoint identifier
>>> oracle = pipeline(
...     "question-answering", model="distilbert/distilbert-base-cased-distilled-squad", tokenizer="google-bert/bert-base-cased"
... )

>>> # Named entity recognition pipeline, passing in a specific model and tokenizer
>>> model = AutoModelForTokenClassification.from_pretrained("dbmdz/bert-large-cased-finetuned-conll03-english")
>>> tokenizer = AutoTokenizer.from_pretrained("google-bert/bert-base-cased")
>>> recognizer = pipeline("ner", model=model, tokenizer=tokenizer)

model (`str` or [PreTrainedModel](/docs/transformers/v5.0.0rc1/en/main_classes/model#transformers.PreTrainedModel), *optional*) : The model that will be used by the pipeline to make predictions. This can be a model identifier or an actual instance of a pretrained model inheriting from [PreTrainedModel](/docs/transformers/v5.0.0rc1/en/main_classes/model#transformers.PreTrainedModel).  If not provided, the default for the `task` will be loaded.

config (`str` or [PreTrainedConfig](/docs/transformers/v5.0.0rc1/en/main_classes/configuration#transformers.PreTrainedConfig), *optional*) : The configuration that will be used by the pipeline to instantiate the model. This can be a model identifier or an actual pretrained model configuration inheriting from [PreTrainedConfig](/docs/transformers/v5.0.0rc1/en/main_classes/configuration#transformers.PreTrainedConfig).  If not provided, the default configuration file for the requested model will be used. That means that if `model` is given, its default configuration will be used. However, if `model` is not supplied, this `task`'s default model's config is used instead.

tokenizer (`str` or [PreTrainedTokenizer](/docs/transformers/v5.0.0rc1/en/main_classes/tokenizer#transformers.PythonBackend), *optional*) : The tokenizer that will be used by the pipeline to encode data for the model. This can be a model identifier or an actual pretrained tokenizer inheriting from [PreTrainedTokenizer](/docs/transformers/v5.0.0rc1/en/main_classes/tokenizer#transformers.PythonBackend).  If not provided, the default tokenizer for the given `model` will be loaded (if it is a string). If `model` is not specified or not a string, then the default tokenizer for `config` is loaded (if it is a string). However, if `config` is also not given or not a string, then the default tokenizer for the given `task` will be loaded.

feature_extractor (`str` or `PreTrainedFeatureExtractor`, *optional*) : The feature extractor that will be used by the pipeline to encode data for the model. This can be a model identifier or an actual pretrained feature extractor inheriting from `PreTrainedFeatureExtractor`.  Feature extractors are used for non-NLP models, such as Speech or Vision models as well as multi-modal models. Multi-modal models will also require a tokenizer to be passed.  If not provided, the default feature extractor for the given `model` will be loaded (if it is a string). If `model` is not specified or not a string, then the default feature extractor for `config` is loaded (if it is a string). However, if `config` is also not given or not a string, then the default feature extractor for the given `task` will be loaded.

image_processor (`str` or [BaseImageProcessor](/docs/transformers/v5.0.0rc1/en/main_classes/image_processor#transformers.BaseImageProcessor), *optional*) : The image processor that will be used by the pipeline to preprocess images for the model. This can be a model identifier or an actual image processor inheriting from [BaseImageProcessor](/docs/transformers/v5.0.0rc1/en/main_classes/image_processor#transformers.BaseImageProcessor).  Image processors are used for Vision models and multi-modal models that require image inputs. Multi-modal models will also require a tokenizer to be passed.  If not provided, the default image processor for the given `model` will be loaded (if it is a string). If `model` is not specified or not a string, then the default image processor for `config` is loaded (if it is a string).

processor (`str` or [ProcessorMixin](/docs/transformers/v5.0.0rc1/en/main_classes/processors#transformers.ProcessorMixin), *optional*) : The processor that will be used by the pipeline to preprocess data for the model. This can be a model identifier or an actual processor inheriting from [ProcessorMixin](/docs/transformers/v5.0.0rc1/en/main_classes/processors#transformers.ProcessorMixin).  Processors are used for multi-modal models that require multi-modal inputs, for example, a model that requires both text and image inputs.  If not provided, the default processor for the given `model` will be loaded (if it is a string). If `model` is not specified or not a string, then the default processor for `config` is loaded (if it is a string).

revision (`str`, *optional*, defaults to `"main"`) : When passing a task name or a string model identifier: 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.

use_fast (`bool`, *optional*, defaults to `True`) : Whether or not to use a Fast tokenizer if possible (a [PreTrainedTokenizerFast](/docs/transformers/v5.0.0rc1/en/main_classes/tokenizer#transformers.TokenizersBackend)).

device (`int` or `str` or `torch.device`) : Defines the device (*e.g.*, `"cpu"`, `"cuda:1"`, `"mps"`, or a GPU ordinal rank like `1`) on which this pipeline will be allocated.

device_map (`str` or `dict[str, Union[int, str, torch.device]`, *optional*) : Sent directly as `model_kwargs` (just a simpler shortcut). When `accelerate` library is present, set `device_map="auto"` to compute the most optimized `device_map` automatically (see [here](https://huggingface.co/docs/accelerate/main/en/package_reference/big_modeling#accelerate.cpu_offload) for more information).    Do not use `device_map` AND `device` at the same time as they will conflict   

dtype (`str` or `torch.dtype`, *optional*) : Sent directly as `model_kwargs` (just a simpler shortcut) to use the available precision for this model (`torch.float16`, `torch.bfloat16`, ... or `"auto"`).

trust_remote_code (`bool`, *optional*, defaults to `False`) : Whether or not to allow for custom code defined on the Hub in their own modeling, configuration, tokenization or even pipeline 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.

model_kwargs (`dict[str, Any]`, *optional*) : Additional dictionary of keyword arguments passed along to the model's `from_pretrained(..., **model_kwargs)` function.

kwargs (`dict[str, Any]`, *optional*) : Additional keyword arguments passed along to the specific pipeline init (see the documentation for the corresponding pipeline class for possible values).

**Returns:**

`[Pipeline](/docs/transformers/v5.0.0rc1/en/main_classes/pipelines#transformers.Pipeline)`

A suitable pipeline for the task.

## Pipeline batching

All pipelines can use batching. This will work
whenever the pipeline uses its streaming ability (so when passing lists or `Dataset` or `generator`).

```python
from transformers import pipeline
from transformers.pipelines.pt_utils import KeyDataset
import datasets

dataset = datasets.load_dataset("imdb", name="plain_text", split="unsupervised")
pipe = pipeline("text-classification", device=0)
for out in pipe(KeyDataset(dataset, "text"), batch_size=8, truncation="only_first"):
    print(out)
    # [{'label': 'POSITIVE', 'score': 0.9998743534088135}]
    # Exactly the same output as before, but the content are passed
    # as batches to the model
```

However, this is not automatically a win for performance. It can be either a 10x speedup or 5x slowdown depending
on hardware, data and the actual model being used.

Example where it's mostly a speedup:

```python
from transformers import pipeline
from torch.utils.data import Dataset
from tqdm.auto import tqdm

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

class MyDataset(Dataset):
    def __len__(self):
        return 5000

    def __getitem__(self, i):
        return "This is a test"

dataset = MyDataset()

for batch_size in [1, 8, 64, 256]:
    print("-" * 30)
    print(f"Streaming batch_size={batch_size}")
    for out in tqdm(pipe(dataset, batch_size=batch_size), total=len(dataset)):
        pass
```

```text

    for out in tqdm(pipe(dataset, batch_size=256), total=len(dataset)):
....
    q = q / math.sqrt(dim_per_head)  # (bs, n_heads, q_length, dim_per_head)
RuntimeError: CUDA out of memory. Tried to allocate 376.00 MiB (GPU 0; 3.95 GiB total capacity; 1.72 GiB already allocated; 354.88 MiB free; 2.46 GiB reserved in total by PyTorch)
```

There are no good (general) solutions for this problem, and your mileage may vary depending on your use cases. Rule of
thumb:

For users, a rule of thumb is:

- **Measure performance on your load, with your hardware. Measure, measure, and keep measuring. Real numbers are the
  only way to go.**
- If you are latency constrained (live product doing inference), don't batch.
- If you are using CPU, don't batch.
- If you are using throughput (you want to run your model on a bunch of static data), on GPU, then:

  - If you have no clue about the size of the sequence_length ("natural" data), by default don't batch, measure and
    try tentatively to add it, add OOM checks to recover when it will fail (and it will at some point if you don't
    control the sequence_length.)
  - If your sequence_length is super regular, then batching is more likely to be VERY interesting, measure and push
    it until you get OOMs.
  - The larger the GPU the more likely batching is going to be more interesting
- As soon as you enable batching, make sure you can handle OOMs nicely.

## Pipeline chunk batching

`zero-shot-classification` and `question-answering` are slightly specific in the sense, that a single input might yield
multiple forward pass of a model. Under normal circumstances, this would yield issues with `batch_size` argument.

In order to circumvent this issue, both of these pipelines are a bit specific, they are `ChunkPipeline` instead of
regular `Pipeline`. In short:

```python
preprocessed = pipe.preprocess(inputs)
model_outputs = pipe.forward(preprocessed)
outputs = pipe.postprocess(model_outputs)
```

Now becomes:

```python
all_model_outputs = []
for preprocessed in pipe.preprocess(inputs):
    model_outputs = pipe.forward(preprocessed)
    all_model_outputs.append(model_outputs)
outputs = pipe.postprocess(all_model_outputs)
```

This should be very transparent to your code because the pipelines are used in
the same way.

This is a simplified view, since the pipeline can handle automatically the batch to ! Meaning you don't have to care
about how many forward passes you inputs are actually going to trigger, you can optimize the `batch_size`
independently of the inputs. The caveats from the previous section still apply.

## Pipeline FP16 inference

Models can be run in FP16 which can be significantly faster on GPU while saving memory. Most models will not suffer noticeable performance loss from this. The larger the model, the less likely that it will.

To enable FP16 inference, you can simply pass `dtype=torch.float16` or `dtype='float16'` to the pipeline constructor. Note that this only works for models with a PyTorch backend. Your inputs will be converted to FP16 internally.

## Pipeline custom code

If you want to override a specific pipeline.

Don't hesitate to create an issue for your task at hand, the goal of the pipeline is to be easy to use and support most
cases, so `transformers` could maybe support your use case.

If you want to try simply you can:

- Subclass your pipeline of choice

```python
class MyPipeline(TextClassificationPipeline):
    def postprocess():
        # Your code goes here
        scores = scores * 100
        # And here

my_pipeline = MyPipeline(model=model, tokenizer=tokenizer, ...)
# or if you use *pipeline* function, then:
my_pipeline = pipeline(model="xxxx", pipeline_class=MyPipeline)
```

That should enable you to do all the custom code you want.

Audio classification pipeline using any `AutoModelForAudioClassification`. This pipeline predicts the class of a
raw waveform or an audio file. In case of an audio file, ffmpeg should be installed to support multiple audio
formats.

Example:

```python
>>> from transformers import pipeline

>>> classifier = pipeline(model="superb/wav2vec2-base-superb-ks")
>>> classifier("https://huggingface.co/datasets/Narsil/asr_dummy/resolve/main/1.flac")
[{'score': 0.997, 'label': '_unknown_'}, {'score': 0.002, 'label': 'left'}, {'score': 0.0, 'label': 'yes'}, {'score': 0.0, 'label': 'down'}, {'score': 0.0, 'label': 'stop'}]
```

  The inputs is either :
  - `str` that is the filename of 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 either be in the format `{"sampling_rate": int,
    "raw": np.array}`, or `{"sampling_rate": int, "array": np.array}`, where the key `"raw"` or
    `"array"` is used to denote the raw audio waveform.
- **top_k** (`int`, *optional*, defaults to None) --
  The number of top labels that will be returned by the pipeline. If the provided number is `None` or
  higher than the number of labels available in the model configuration, it will default to the number of
  labels.
- **function_to_apply(`str`,** *optional*, defaults to "softmax") --
  The function to apply to the model output. By default, the pipeline will apply the softmax function to
  the output of the model. Valid options: ["softmax", "sigmoid", "none"]. Note that passing Python's
  built-in `None` will default to "softmax", so you need to pass the string "none" to disable any
  post-processing.0A list of `dict` with the following keys- **label** (`str`) -- The label predicted.
- **score** (`float`) -- The corresponding probability.

[Source](https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/automatic_speech_recognition.py#L112)

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

Unless the model you're using explicitly sets these generation parameters in its configuration files
(`generation_config.json`), the following default values will be used:
- max_new_tokens: 256
- num_beams: 5

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.'}
```

  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).0`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"])`.

Transcribe the audio sequence(s) given as inputs to text. See the [AutomaticSpeechRecognitionPipeline](/docs/transformers/v5.0.0rc1/en/main_classes/pipelines#transformers.AutomaticSpeechRecognitionPipeline)
documentation for more information.

**Parameters:**

model ([PreTrainedModel](/docs/transformers/v5.0.0rc1/en/main_classes/model#transformers.PreTrainedModel)) : The model that will be used by the pipeline to make predictions. This needs to be a model inheriting from [PreTrainedModel](/docs/transformers/v5.0.0rc1/en/main_classes/model#transformers.PreTrainedModel).

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).    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).   

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.

Zero shot image classification pipeline using `CLIPModel`. This pipeline predicts the class of an image when you
provide an image and a set of `candidate_labels`.

Example:

```python
>>> from transformers import pipeline

>>> classifier = pipeline(model="google/siglip-so400m-patch14-384")
>>> classifier(
...     "https://huggingface.co/datasets/Narsil/image_dummy/raw/main/parrots.png",
...     candidate_labels=["animals", "humans", "landscape"],
... )
[{'score': 0.965, 'label': 'animals'}, {'score': 0.03, 'label': 'humans'}, {'score': 0.005, 'label': 'landscape'}]

>>> classifier(
...     "https://huggingface.co/datasets/Narsil/image_dummy/raw/main/parrots.png",
...     candidate_labels=["black and white", "photorealist", "painting"],
... )
[{'score': 0.996, 'label': 'black and white'}, {'score': 0.003, 'label': 'photorealist'}, {'score': 0.0, 'label': 'painting'}]

Table Question Answering pipeline using a `ModelForTableQuestionAnswering`. This pipeline is only available in
PyTorch.

Unless the model you're using explicitly sets these generation parameters in its configuration files
(`generation_config.json`), the following default values will be used:
- max_new_tokens: 256

Example:

```python
>>> from transformers import pipeline

>>> oracle = pipeline(model="google/tapas-base-finetuned-wtq")
>>> table = {
...     "Repository": ["Transformers", "Datasets", "Tokenizers"],
...     "Stars": ["36542", "4512", "3934"],

...     "Programming language": ["Python", "Python", "Rust, Python and NodeJS"],
... }
>>> oracle(query="How many stars does the transformers repository have?", table=table)
{'answer': 'AVERAGE > 36542', 'coordinates': [(0, 1)], 'cells': ['36542'], 'aggregator': 'AVERAGE'}

#### transformers.TextGenerationPipeline[[transformers.TextGenerationPipeline]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/text_generation.py#L23)

Language generation pipeline using any `ModelWithLMHead` or `ModelForCausalLM`. This pipeline predicts the words
that will follow a specified text prompt. When the underlying model is a conversational model, it can also accept
one or more chats, in which case the pipeline will operate in chat mode and will continue the chat(s) by adding
its response(s). Each chat takes the form of a list of dicts, where each dict contains "role" and "content" keys.

Unless the model you're using explicitly sets these generation parameters in its configuration files
(`generation_config.json`), the following default values will be used:
- max_new_tokens: 256
- do_sample: True
- temperature: 0.7

Examples:

```python
>>> from transformers import pipeline

>>> generator = pipeline(model="openai-community/gpt2")
>>> generator("I can't believe you did such a ", do_sample=False)
[{'generated_text': "I can't believe you did such a icky thing to me. I'm so sorry. I'm so sorry. I'm so sorry. I'm so sorry. I'm so sorry. I'm so sorry. I'm so sorry. I"}]

>>> # These parameters will return suggestions, and only the newly created text making it easier for prompting suggestions.
>>> outputs = generator("My tart needs some", num_return_sequences=4, return_full_text=False)
```

```python
>>> from transformers import pipeline

>>> generator = pipeline(model="HuggingFaceH4/zephyr-7b-beta")
>>> # Zephyr-beta is a conversational model, so let's pass it a chat instead of a single string
>>> generator([{"role": "user", "content": "What is the capital of France? Answer in one word."}], do_sample=False, max_new_tokens=2)
[{'generated_text': [{'role': 'user', 'content': 'What is the capital of France? Answer in one word.'}, {'role': 'assistant', 'content': 'Paris'}]}]
```

  One or several prompts (or one list of prompts) to complete. If strings or a list of string are
  passed, this pipeline will continue each prompt. Alternatively, a "chat", in the form of a list
  of dicts with "role" and "content" keys, can be passed, or a list of such chats. When chats are passed,
  the model's chat template will be used to format them before passing them to the model.
- **return_tensors** (`bool`, *optional*, defaults to `False`) --
  Returns the tensors of predictions (as token indices) in the outputs. If set to
  `True`, the decoded text is not returned.
- **return_text** (`bool`, *optional*) --
  Returns the decoded texts in the outputs.
- **return_full_text** (`bool`, *optional*, defaults to `True`) --
  If set to `False` only added text is returned, otherwise the full text is returned. Cannot be
  specified at the same time as `return_text`.
- **clean_up_tokenization_spaces** (`bool`, *optional*, defaults to `True`) --
  Whether or not to clean up the potential extra spaces in the text output.
- **continue_final_message(** `bool`, *optional*) -- This indicates that you want the model to continue the
  last message in the input chat rather than starting a new one, allowing you to "prefill" its response.
  By default this is `True` when the final message in the input chat has the `assistant` role and
  `False` otherwise, but you can manually override that behaviour by setting this flag.
- **prefix** (`str`, *optional*) --
  Prefix added to prompt.
- **handle_long_generation** (`str`, *optional*) --
  By default, this pipelines does not handle long generation (ones that exceed in one form or the other
  the model maximum length). There is no perfect way to address this (more info
  :https://github.com/huggingface/transformers/issues/14033#issuecomment-948385227). This provides common
  strategies to work around that problem depending on your use case.

  - `None` : default strategy where nothing in particular happens
  - `"hole"`: Truncates left of input, and leaves a gap wide enough to let generation happen (might
    truncate a lot of the prompt and not suitable when generation exceed the model capacity)
- **tokenizer_encode_kwargs** (`dict`, *optional*) --
  Additional keyword arguments to pass along to the encoding step of the tokenizer. If the text input is
  a chat, it is passed to `apply_chat_template`. Otherwise, it is passed to `__call__`.
- **generate_kwargs** (`dict`, *optional*) --
  Additional keyword arguments to pass along to the generate method of the model (see the generate method
  [here](./text_generation)).0A list or a list of lists of `dict`Returns one of the following dictionaries (cannot return a combination
of both `generated_text` and `generated_token_ids`):

This token recognition pipeline can currently be loaded from [pipeline()](/docs/transformers/v5.0.0rc1/en/main_classes/pipelines#transformers.pipeline) using the following task identifier:
`"ner"` (for predicting the classes of tokens in a sequence: person, organisation, location or miscellaneous).

The models that this pipeline can use are models that have been fine-tuned on a token classification task. See the
up-to-date list of available models on
[huggingface.co/models](https://huggingface.co/models?filter=token-classification).

  One or several texts (or one list of texts) for token classification. Can be pre-tokenized when
  `is_split_into_words=True`.0A list or a list of list of `dict`Each result comes as a list of dictionaries (one for each token in the
corresponding input, or each entity if this pipeline was instantiated with an aggregation_strategy) with
the following keys:

- **word** (`str`) -- The token/word classified. This is obtained by decoding the selected tokens. If you
  want to have the exact string in the original sentence, use `start` and `end`.
- **score** (`float`) -- The corresponding probability for `entity`.
- **entity** (`str`) -- The entity predicted for that token/word (it is named *entity_group* when
  *aggregation_strategy* is not `"none"`.

  token in the sentence.
- **start** (`int`, *optional*) -- The index of the start of the corresponding entity in the sentence. Only
  exists if the offsets are available within the tokenizer
- **end** (`int`, *optional*) -- The index of the end of the corresponding entity in the sentence. Only
  exists if the offsets are available within the tokenizer

Classify each token of the text(s) given as inputs.

**Parameters:**

model ([PreTrainedModel](/docs/transformers/v5.0.0rc1/en/main_classes/model#transformers.PreTrainedModel)) : The model that will be used by the pipeline to make predictions.

device (`int`, *optional*, defaults to -1) : Device ordinal for CPU/GPU supports. Setting this to -1 will leverage CPU, a positive will run the model on the associated CUDA device id. You can pass native `torch.device` or a `str` too

dtype (`str` or `torch.dtype`, *optional*) : Sent directly as `model_kwargs` (just a simpler shortcut) to use the available precision for this model (`torch.float16`, `torch.bfloat16`, ... or `"auto"`)

binary_output (`bool`, *optional*, defaults to `False`) : Flag indicating if the output the pipeline should happen in a serialized format (i.e., pickle) or as the raw output data e.g. text.

ignore_labels (`list[str]`, defaults to `["O"]`) : A list of labels to ignore.

grouped_entities (`bool`, *optional*, defaults to `False`) : DEPRECATED, use `aggregation_strategy` instead. Whether or not to group the tokens corresponding to the same entity together in the predictions or not.

stride (`int`, *optional*) : If stride is provided, the pipeline is applied on all the text. The text is split into chunks of size model_max_length. Works only with fast tokenizers and `aggregation_strategy` different from `NONE`. The value of this argument defines the number of overlapping tokens between chunks. In other words, the model will shift forward by `tokenizer.model_max_length - stride` tokens each step.

aggregation_strategy (`str`, *optional*, defaults to `"none"`) : The strategy to fuse (or not) tokens based on the model prediction.  - "none" : Will simply not do any aggregation and simply return raw results from the model - "simple" : Will attempt to group entities following the default schema. (A, B-TAG), (B, I-TAG), (C, I-TAG), (D, B-TAG2) (E, B-TAG2) will end up being [{"word": ABC, "entity": "TAG"}, {"word": "D", "entity": "TAG2"}, {"word": "E", "entity": "TAG2"}] Notice that two consecutive B tags will end up as different entities. On word based languages, we might end up splitting words undesirably : Imagine Microsoft being tagged as [{"word": "Micro", "entity": "ENTERPRISE"}, {"word": "soft", "entity": "NAME"}]. Look for FIRST, MAX, AVERAGE for ways to mitigate that and disambiguate words (on languages that support that meaning, which is basically tokens separated by a space). These mitigations will only work on real words, "New york" might still be tagged with two different entities. - "first" : (works only on word based models) Will use the `SIMPLE` strategy except that words, cannot end up with different tags. Words will simply use the tag of the first token of the word when there is ambiguity. - "average" : (works only on word based models) Will use the `SIMPLE` strategy except that words, cannot end up with different tags. scores will be averaged first across tokens, and then the maximum label is applied. - "max" : (works only on word based models) Will use the `SIMPLE` strategy except that words, cannot end up with different tags. Word entity will simply be the token with the maximum score.

**Returns:**

`A list or a list of list of `dict``

Each result comes as a list of dictionaries (one for each token in the
corresponding input, or each entity if this pipeline was instantiated with an aggregation_strategy) with

#### transformers.ZeroShotClassificationPipeline[[transformers.ZeroShotClassificationPipeline]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/zero_shot_classification.py#L44)

NLI-based zero-shot classification pipeline using a `ModelForSequenceClassification` trained on NLI (natural
language inference) tasks. Equivalent of `text-classification` pipelines, but these models don't require a
hardcoded number of potential classes, they can be chosen at runtime. It usually means it's slower but it is
**much** more flexible.

Any combination of sequences and labels can be passed and each combination will be posed as a premise/hypothesis
pair and passed to the pretrained model. Then, the logit for *entailment* is taken as the logit for the candidate
label being valid. Any NLI model can be used, but the id of the *entailment* label must be included in the model
config's :attr:*~transformers.PreTrainedConfig.label2id*.

Example:

```python
>>> from transformers import pipeline

>>> oracle = pipeline(model="facebook/bart-large-mnli")
>>> oracle(
...     "I have a problem with my iphone that needs to be resolved asap!!",
...     candidate_labels=["urgent", "not urgent", "phone", "tablet", "computer"],
... )
{'sequence': 'I have a problem with my iphone that needs to be resolved asap!!', 'labels': ['urgent', 'phone', 'computer', 'not urgent', 'tablet'], 'scores': [0.504, 0.479, 0.013, 0.003, 0.002]}

>>> oracle(
...     "I have a problem with my iphone that needs to be resolved asap!!",
...     candidate_labels=["english", "german"],
... )
{'sequence': 'I have a problem with my iphone that needs to be resolved asap!!', 'labels': ['english', 'german'], 'scores': [0.814, 0.186]}

This document question answering pipeline can currently be loaded from [pipeline()](/docs/transformers/v5.0.0rc1/en/main_classes/pipelines#transformers.pipeline) using the following task
identifier: `"document-question-answering"`.

The models that this pipeline can use are models that have been fine-tuned on a document question answering task.
See the up-to-date list of available models on
[huggingface.co/models](https://huggingface.co/models?filter=document-question-answering).

__call__transformers.DocumentQuestionAnsweringPipeline.__call__https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/document_question_answering.py#L233[{"name": "image", "val": ": typing.Union[ForwardRef('Image.Image'), str, list[dict[str, typing.Any]]]"}, {"name": "question", "val": ": str | None = None"}, {"name": "word_boxes", "val": ": tuple[str, list[float]] | None = None"}, {"name": "**kwargs", "val": ": typing.Any"}]- **image** (`str` or `PIL.Image`) --
  The pipeline handles three types of images:

  - A string containing a http link pointing to an image
  - A string containing a local path to an image
  - An image loaded in PIL directly

  The pipeline accepts either a single image or a batch of images. If given a single image, it can be
  broadcasted to multiple questions.
- **question** (`str`) --
  A question to ask of the document.
- **word_boxes** (`list[str, tuple[float, float, float, float]]`, *optional*) --
  A list of words and bounding boxes (normalized 0->1000). If you provide this optional input, then the
  pipeline will use these words and boxes instead of running OCR on the image to derive them for models
  that need them (e.g. LayoutLM). This allows you to reuse OCR'd results across many invocations of the
  pipeline without having to re-run it each time.
- **top_k** (`int`, *optional*, defaults to 1) --
  The number of answers to return (will be chosen by order of likelihood). Note that we return less than
  top_k answers if there are not enough options available within the context.
- **doc_stride** (`int`, *optional*, defaults to 128) --
  If the words in the document are too long to fit with the question for the model, it will be split in
  several chunks with some overlap. This argument controls the size of that overlap.
- **max_answer_len** (`int`, *optional*, defaults to 15) --
  The maximum length of predicted answers (e.g., only answers with a shorter length are considered).
- **max_seq_len** (`int`, *optional*, defaults to 384) --
  The maximum length of the total sentence (context + question) in tokens of each chunk passed to the
  model. The context will be split in several chunks (using `doc_stride` as overlap) if needed.
- **max_question_len** (`int`, *optional*, defaults to 64) --
  The maximum length of the question after tokenization. It will be truncated if needed.
- **handle_impossible_answer** (`bool`, *optional*, defaults to `False`) --
  Whether or not we accept impossible as an answer.
- **lang** (`str`, *optional*) --
  Language to use while running OCR. Defaults to english.
- **tesseract_config** (`str`, *optional*) --
  Additional flags to pass to tesseract while running OCR.
- **timeout** (`float`, *optional*, defaults to None) --
  The maximum time in seconds to wait for fetching images from the web. If None, no timeout is set and
  the call may block forever.0A `dict` or a list of `dict`Each result comes as a dictionary with the following keys:

- **score** (`float`) -- The probability associated to the answer.
- **start** (`int`) -- The start word index of the answer (in the OCR'd version of the input or provided
  `word_boxes`).
- **end** (`int`) -- The end word index of the answer (in the OCR'd version of the input or provided
  `word_boxes`).
- **answer** (`str`) -- The answer to the question.
- **words** (`list[int]`) -- The index of each word/box pair that is in the answer

Answer the question(s) given as inputs by using the document(s). A document is defined as an image and an
optional list of (word, box) tuples which represent the text in the document. If the `word_boxes` are not
provided, it will use the Tesseract OCR engine (if available) to extract the words and boxes automatically for
LayoutLM-like models which require them as input. For Donut, no OCR is run.

You can invoke the pipeline several ways:

- `pipeline(image=image, question=question)`
- `pipeline(image=image, question=question, word_boxes=word_boxes)`
- `pipeline([{"image": image, "question": question}])`
- `pipeline([{"image": image, "question": question, "word_boxes": word_boxes}])`

Image-text-to-text pipeline using an `AutoModelForImageTextToText`. This pipeline generates text given an image and text.
When the underlying model is a conversational model, it can also accept one or more chats,
in which case the pipeline will operate in chat mode and will continue the chat(s) by adding its response(s).
Each chat takes the form of a list of dicts, where each dict contains "role" and "content" keys.

(`generation_config.json`), the following default values will be used:
- max_new_tokens: 256

  The pipeline handles three types of images:

  - A string containing a HTTP(s) link pointing to an image
  - A string containing a local path to an image
  - An image loaded in PIL directly

  The pipeline accepts either a single image or a batch of images. Finally, this pipeline also supports
  the chat format (see `text`) containing images and text in this argument.
- **text** (str, list[str], `list[dict[str, Union[str, PIL.Image]]]`) --
  The text to be used for generation. If a list of strings is passed, the length of the list should be
  the same as the number of images. Text can also follow the chat format: a list of dictionaries where
  each dictionary represents a message in a conversation. Each dictionary should have two keys: 'role'
  and 'content'. 'role' should be one of 'user', 'system' or 'assistant'. 'content' should be a list of
  dictionary containing the text of the message and the type of the message. The type of the message
  can be either 'text' or 'image'. If the type is 'image', no text is needed.
- **return_tensors** (`bool`, *optional*, defaults to `False`) --
  Returns the tensors of predictions (as token indices) in the outputs. If set to
  `True`, the decoded text is not returned.
- **return_text** (`bool`, *optional*) --
  Returns the decoded texts in the outputs.
- **return_full_text** (`bool`, *optional*, defaults to `True`) --
  If set to `False` only added text is returned, otherwise the full text is returned. Cannot be
  specified at the same time as `return_text`.
- **clean_up_tokenization_spaces** (`bool`, *optional*, defaults to `True`) --
  Whether or not to clean up the potential extra spaces in the text output.
- **continue_final_message(** `bool`, *optional*) -- This indicates that you want the model to continue the
  last message in the input chat rather than starting a new one, allowing you to "prefill" its response.
  By default this is `True` when the final message in the input chat has the `assistant` role and
  `False` otherwise, but you can manually override that behaviour by setting this flag.0A list or a list of list of `dict`Each result comes as a dictionary with the following key (cannot
return a combination of both `generated_text` and `generated_token_ids`):

- **generated_text** (`str`, present when `return_text=True`) -- The generated text.
- **generated_token_ids** (`torch.Tensor`, present when `return_tensors=True`) -- The token
  ids of the generated text.
- **input_text** (`str`) -- The input text.

Generate a text given text and the image(s) passed as inputs.

Multimodal Generation pipeline using an `AutoModelForMultimodalLM`. This pipeline generates text given any
combination of multimodal data and text.When the underlying model is a conversational model, it can also
accept one or more chats, in which case the pipeline will operate in chat mode and will continue the
chat(s) by adding its response(s). Each chat takes the form of a list of dicts, where each dict contains
"role" and "content" keys.

Unless the model you're using explicitly sets these generation parameters in its configuration files
(`generation_config.json`), the following default values will be used:
- max_new_tokens: 256

Example:

```python
>>> from transformers import pipeline

>>> pipe = pipeline(task="any-to-any", model="google/gemma-3n-E4B-it")
>>> pipe("https://huggingface.co/datasets/Narsil/image_dummy/raw/main/parrots.png", text="A photo of")
[{'generated_text': 'a photo of two birds'}]
```

```python
>>> from transformers import pipeline

>>> pipe = pipeline("any-to-any", model="google/gemma-3n-E4B-it")
>>> messages = [
>>>     {
>>>         "role": "user",
>>>         "content": [
>>>             {
>>>                 "type": "image",

>>>             {"type": "text", "text": "There is a dog and"},
>>>         ],
>>>     },
>>> ]
>>> pipe(text=messages, max_new_tokens=20, return_full_text=False)

### MaskGenerationPipeline[[transformers.MaskGenerationPipeline]]

#### transformers.MaskGenerationPipeline[[transformers.MaskGenerationPipeline]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/mask_generation.py#L36)

Automatic mask generation for images using `SamForMaskGeneration`. This pipeline predicts binary masks for an
image, given an image. It is a `ChunkPipeline` because you can separate the points in a mini-batch in order to
avoid OOM issues. Use the `points_per_batch` argument to control the number of points that will be processed at the
same time. Default is `64`.

The pipeline works in 3 steps:
1. `preprocess`: A grid of 1024 points evenly separated is generated along with bounding boxes and point
   labels.
   For more details on how the points and bounding boxes are created, check the `_generate_crop_boxes`
   function. The image is also preprocessed using the `image_processor`. This function `yields` a minibatch of
   `points_per_batch`.

2. `forward`: feeds the outputs of `preprocess` to the model. The image embedding is computed only once.
   Calls both `self.model.get_image_embeddings` and makes sure that the gradients are not computed, and the
   tensors and models are on the same device.

3. `postprocess`: The most important part of the automatic mask generation happens here. Three steps
   are induced:
   - image_processor.postprocess_masks (run on each minibatch loop): takes in the raw output masks,
     resizes them according
   to the image size, and transforms there to binary masks.
   - image_processor.filter_masks (on each minibatch loop): uses both `pred_iou_thresh` and
     `stability_scores`. Also
   applies a variety of filters based on non maximum suppression to remove bad masks.
   - image_processor.postprocess_masks_for_amg applies the NSM on the mask to only keep relevant ones.

Example:

```python
>>> from transformers import pipeline

>>> generator = pipeline(model="facebook/sam-vit-base", task="mask-generation")
>>> outputs = generator(
...     "http://images.cocodataset.org/val2017/000000039769.jpg",
... )

>>> outputs = generator(
...     "https://huggingface.co/datasets/Narsil/image_dummy/raw/main/parrots.png", points_per_batch=128
... )
```

The Pipeline class is the class from which all pipelines inherit. Refer to this class for methods shared across
different pipelines.

Base class implementing pipelined operations. Pipeline workflow is defined as a sequence of the following
operations:

Input -> Tokenization -> Model Inference -> Post-Processing (task dependent) -> Output

Pipeline supports running on CPU or GPU through the device argument (see below).

Some pipeline, like for instance [FeatureExtractionPipeline](/docs/transformers/v5.0.0rc1/en/main_classes/pipelines#transformers.FeatureExtractionPipeline) (`'feature-extraction'`) output large tensor object
as nested-lists. In order to avoid dumping such large structure as textual data we provide the `binary_output`
constructor argument. If set to `True`, the output will be stored in the pickle format.

  The list of models supported by the pipeline, or a dictionary with model class values.0

Check if the model class is in supported by the pipeline.

**Parameters:**

model ([PreTrainedModel](/docs/transformers/v5.0.0rc1/en/main_classes/model#transformers.PreTrainedModel)) : The model that will be used by the pipeline to make predictions. This needs to be a model inheriting from [PreTrainedModel](/docs/transformers/v5.0.0rc1/en/main_classes/model#transformers.PreTrainedModel).

tokenizer ([PreTrainedTokenizer](/docs/transformers/v5.0.0rc1/en/main_classes/tokenizer#transformers.PythonBackend)) : The tokenizer that will be used by the pipeline to encode data for the model. This object inherits from [PreTrainedTokenizer](/docs/transformers/v5.0.0rc1/en/main_classes/tokenizer#transformers.PythonBackend).

feature_extractor ([SequenceFeatureExtractor](/docs/transformers/v5.0.0rc1/en/main_classes/feature_extractor#transformers.SequenceFeatureExtractor)) : The feature extractor that will be used by the pipeline to encode data for the model. This object inherits from [SequenceFeatureExtractor](/docs/transformers/v5.0.0rc1/en/main_classes/feature_extractor#transformers.SequenceFeatureExtractor).

image_processor ([BaseImageProcessor](/docs/transformers/v5.0.0rc1/en/main_classes/image_processor#transformers.BaseImageProcessor)) : The image processor that will be used by the pipeline to encode data for the model. This object inherits from [BaseImageProcessor](/docs/transformers/v5.0.0rc1/en/main_classes/image_processor#transformers.BaseImageProcessor).

processor ([ProcessorMixin](/docs/transformers/v5.0.0rc1/en/main_classes/processors#transformers.ProcessorMixin)) : The processor that will be used by the pipeline to encode data for the model. This object inherits from [ProcessorMixin](/docs/transformers/v5.0.0rc1/en/main_classes/processors#transformers.ProcessorMixin). Processor is a composite object that might contain `tokenizer`, `feature_extractor`, and `image_processor`.

modelcard (`str` or `ModelCard`, *optional*) : Model card attributed to the model for this pipeline.

task (`str`, defaults to `""`) : A task-identifier for the pipeline.

num_workers (`int`, *optional*, defaults to 8) : When the pipeline will use *DataLoader* (when passing a dataset, on GPU for a Pytorch model), the number of workers to be used.

batch_size (`int`, *optional*, defaults to 1) : When the pipeline will use *DataLoader* (when passing a dataset, on GPU for a Pytorch model), the size of the batch to use, for inference this is not always beneficial, please read [Batching with pipelines](https://huggingface.co/transformers/main_classes/pipelines.html#pipeline-batching) .

args_parser ([ArgumentHandler](/docs/transformers/v5.0.0rc1/en/internal/pipelines_utils#transformers.pipelines.ArgumentHandler), *optional*) : Reference to the object in charge of parsing supplied pipeline parameters.

device (`int`, *optional*, defaults to -1) : Device ordinal for CPU/GPU supports. Setting this to -1 will leverage CPU, a positive will run the model on the associated CUDA device id. You can pass native `torch.device` or a `str` too

dtype (`str` or `torch.dtype`, *optional*) : Sent directly as `model_kwargs` (just a simpler shortcut) to use the available precision for this model (`torch.float16`, `torch.bfloat16`, ... or `"auto"`)

binary_output (`bool`, *optional*, defaults to `False`) : Flag indicating if the output the pipeline should happen in a serialized format (i.e., pickle) or as the raw output data e.g. text.
#### device_placement[[transformers.Pipeline.device_placement]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/base.py#L1029)

Context Manager allowing tensor allocation on the user-specified device.

Examples:

```python
# Explicitly ask for tensor allocation on CUDA device :0
pipe = pipeline(..., device=0)
with pipe.device_placement():
    # Every tensor allocation will be done on the request device
    output = pipe(...)
```

**Returns:**

Context manager
#### ensure_tensor_on_device[[transformers.Pipeline.ensure_tensor_on_device]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/base.py#L1061)

Ensure PyTorch tensors are on the specified device.

**Parameters:**

inputs (keyword arguments that should be `torch.Tensor`, the rest is ignored) : The tensors to place on `self.device`.

Recursive on lists **only**. --

**Returns:**

``dict[str, torch.Tensor]``

The same as `inputs` but on the proper device.
#### postprocess[[transformers.Pipeline.postprocess]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/base.py#L1160)

Postprocess will receive the raw outputs of the `_forward` method, generally tensors, and reformat them into
something more friendly. Generally it will output a list or a dict or results (containing just strings and
numbers).
#### predict[[transformers.Pipeline.predict]]

[Source](https://github.com/huggingface/transformers/blob/v5.0.0rc1/src/transformers/pipelines/base.py#L1008)
