추론

추론은 학습된 모델을 사용하여 새로운 데이터를 예측하는 과정입니다. 이 과정은 계산량이 많을 수 있기 때문에, 전용 서버에서 실행하는 것이 흥미로운 옵션이 될 수 있습니다. `huggingface_hub` 라이브러리는 호스팅된 모델에 대한 추론을 실행하는 간단한 방법을 제공합니다. 연결할 수 있는 서비스는 여러가지가 있습니다:

- 추론 API: Hugging Face의 인프라에서 가속화된 추론을 무료로 실행할 수 있는 서비스입니다. 이 서비스는 시작하기 위한 빠른 방법이며, 다양한 모델을 테스트하고 AI 제품을 프로토타입화하는 데에도 유용합니다.
- 추론 엔드포인트: 모델을 쉽게 운영 환경으로 배포할 수 있는 제품입니다. 추론은 여러분이 선택한 클라우드 제공업체의 전용 및 완전히 관리되는 인프라에서 Hugging Face에 의해 실행됩니다.

이러한 서비스는 InferenceClient 객체를 사용하여 호출할 수 있습니다. 자세한 사용 방법에 대해서는 이 가이드를 참조해주세요.

class huggingface_hub.InferenceClient

< source >

( model: Optional = None token: Union = None timeout: Optional = None headers: Optional = None cookies: Optional = None proxies: Optional = None )

Parameters

- model (`str`, `optional`) — The model to run inference with. Can be a model id hosted on the Hugging Face Hub, e.g. `bigcode/starcoder` or a URL to a deployed Inference Endpoint. Defaults to None, in which case a recommended model is automatically selected for the task.
- token (`str` or `bool`, optional) — Hugging Face token. Will default to the locally saved token if not provided. Pass `token=False` if you don’t want to send your token to the server.
- timeout (`float`, `optional`) — The maximum number of seconds to wait for a response from the server. Loading a new model in Inference API can take up to several minutes. Defaults to None, meaning it will loop until the server is available.
- headers (`Dict[str, str]`, `optional`) — Additional headers to send to the server. By default only the authorization and user-agent headers are sent. Values in this dictionary will override the default values.
- cookies (`Dict[str, str]`, `optional`) — Additional cookies to send to the server.

Initialize a new Inference Client.

InferenceClient aims to provide a unified experience to perform inference. The client can be used seamlessly with either the (free) Inference API or self-hosted Inference Endpoints.

ChatCompletionOutput or Iterable of ChatCompletionStreamOutput

Parameters

- messages (List[Union[`SystemMessage`, `UserMessage`, `AssistantMessage`]]) — Conversation history consisting of roles and content pairs.
- model (`str`, optional) — The model to use for chat-completion. Can be a model ID hosted on the Hugging Face Hub or a URL to a deployed Inference Endpoint. If not provided, the default recommended model for chat-based text-generation will be used. See https://huggingface.co/tasks/text-generation for more details.
- frequency_penalty (`float`, optional) — Penalizes new tokens based on their existing frequency in the text so far. Range: [-2.0, 2.0]. Defaults to 0.0.
- logit_bias (`List[float]`, optional) — Modify the likelihood of specified tokens appearing in the completion. Accepts a JSON object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token. Defaults to None.
- logprobs (`bool`, optional) — Whether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the content of message.
- max_tokens (`int`, optional) — Maximum number of tokens allowed in the response. Defaults to 20.
- n (`int`, optional) — UNUSED.
- presence_penalty (`float`, optional) — Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model’s likelihood to talk about new topics.
- seed (Optional`int`, optional) — Seed for reproducible control flow. Defaults to None.
- stop (Optional`str`, optional) — Up to four strings which trigger the end of the response. Defaults to None.
- stream (`bool`, optional) — Enable realtime streaming of responses. Defaults to False.
- temperature (`float`, optional) — Controls randomness of the generations. Lower values ensure less random completions. Range: [0, 2]. Defaults to 1.0.
- top_logprobs (`int`, optional) — An integer between 0 and 5 specifying the number of most likely tokens to return at each token position, each with an associated log probability. logprobs must be set to true if this parameter is used.
- top_p (`float`, optional) — Fraction of the most likely next words to sample from. Must be between 0 and 1. Defaults to 1.0.
- tool_choice (ChatCompletionInputToolTypeClass or `ChatCompletionInputToolTypeEnum`, optional) — The tool to use for the completion. Defaults to “auto”.
- tool_prompt (`str`, optional) — A prompt to be appended before the tools.
- tools (List of ChatCompletionInputTool, optional) — A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for.
- model_id (`str`, optional) — The model ID to use for chat-completion. Only used when `model` is a URL to a deployed Text Generation Inference server. It is passed to the server as the `model` parameter. This parameter has no impact on the URL that will be used to send the request.

Returns

ChatCompletionOutput or Iterable of ChatCompletionStreamOutput

Generated text returned from the server:

- if `stream=False`, the generated text is returned as a ChatCompletionOutput (default).
- if `stream=True`, the generated text is returned token by token as a sequence of ChatCompletionStreamOutput.

Raises

InferenceTimeoutError or `HTTPError`

- InferenceTimeoutError — If the model is unavailable or the request times out.
- `HTTPError` — If the request fails with an HTTP error status code other than HTTP 503.

get_model_status

< source >

( model: Optional = None ) →
`ModelStatus`

Parameters

- model (`str`, optional) — Identifier of the model for witch the status gonna be checked. If model is not provided, the model associated with this instance of InferenceClient will be used. Only InferenceAPI service can be checked so the identifier cannot be a URL.

Returns

`ModelStatus`

An instance of ModelStatus dataclass, containing information, about the state of the model: load, state, compute type and framework.

Get the status of a model hosted on the Inference API.

This endpoint is mostly useful when you already know which model you want to use and want to check its availability. If you want to discover already deployed models, you should rather use list_deployed_models().

Example:

    >>> from huggingface_hub import InferenceClient
    >>> client = InferenceClient()
    >>> client.get_model_status("bigcode/starcoder")
    ModelStatus(loaded=True, state='Loaded', compute_type='gpu', framework='text-generation-inference')

Returns

`str`

Name of the model recommended for the input task.

Raises

`ValueError`

- `ValueError` — If Hugging Face has no recommendation for the input task.

Get the model Hugging Face recommends for the input task.

####

####
list_deployed_models

< source >

( frameworks: Union = None ) →
`Dict[str, List[str]]`

Parameters

- frameworks (`Literal["all"]` or `List[str]` or `str`, optional) — The frameworks to filter on. By default only a subset of the available frameworks are tested. If set to “all”, all available frameworks will be tested. It is also possible to provide a single framework or a custom set of frameworks to check.

Returns

`Dict[str, List[str]]`

A dictionary mapping task names to a sorted list of model IDs.

List models deployed on the Serverless Inference API service.

This helper checks deployed models framework by framework. By default, it will check the 4 main frameworks that are supported and account for 95% of the hosted models. However, if you want a complete list of models you can specify `frameworks="all"` as input. Alternatively, if you know before-hand which framework you are interested in, you can also restrict to search to this one (e.g. `frameworks="text-generation-inference"`). The more frameworks are checked, the more time it will take.

This endpoint method does not return a live list of all models available for the Serverless Inference API service. It searches over a cached list of models that were recently available and the list may not be up to date. If you want to know the live status of a specific model, use get_model_status().

This endpoint method is mostly useful for discoverability. If you already know which model you want to use and want to check its availability, you can directly use get_model_status().

Example:

    >>> from huggingface_hub import InferenceClient
    >>> client = InferenceClient()

    # Discover zero-shot-classification models currently deployed
    >>> models = client.list_deployed_models()
    >>> models["zero-shot-classification"]
    ['Narsil/deberta-large-mnli-zero-cls', 'facebook/bart-large-mnli', ...]

    # List from only 1 framework
    >>> client.list_deployed_models("text-generation-inference")

Given a prompt, generate the following text.

API endpoint is supposed to run with the `text-generation-inference` backend (TGI). This backend is the go-to solution to run large language models at scale. However, for some smaller models (e.g. “gpt2”) the default `transformers` + `api-inference` solution is still in use. Both approaches have very similar APIs, but not exactly the same. This method is compatible with both approaches but some parameters are only available for `text-generation-inference`. If some parameters are ignored, a warning message is triggered but the process continues correctly.

To learn more about the TGI project, please refer to https://github.com/huggingface/text-generation-inference.

If you want to generate a response from chat messages, you should use the InferenceClient.chat_completion() method. It accepts a list of messages instead of a single text prompt and handles the chat templating for you.

Example:

    >>> client = InferenceClient()

    # Case 1: generate text
    >>> client.text_generation("The huggingface_hub library is ", max_new_tokens=12)
    '100% open source and built to be easy to use.'

    # Case 2: iterate over the generated tokens. Useful for large generation.
    >>> for token in client.text_generation("The huggingface_hub library is ", max_new_tokens=12, stream=True):
    ...     print(token)
    100

Check out https://huggingface.co/tasks/translation for more information on how to choose the best model for your specific use case. Source and target languages usually depend on the model. However, it is possible to specify source and target languages for certain models. If you are working with one of these models, you can use `src_lang` and `tgt_lang` arguments to pass the relevant information. You can find this information in the model card.

Example:

    >>> from huggingface_hub import InferenceClient
    >>> client = InferenceClient()
    >>> client.translation("My name is Wolfgang and I live in Berlin")

zero_shot_classification

< source >

( text: str labels: List multi_label: bool = False hypothesis_template: Optional = None model: Optional = None ) →
`List[ZeroShotClassificationOutputElement]`

Parameters

- text (`str`) — The input text to classify.
- labels (`List[str]`) — List of strings. Each string is the verbalization of a possible label for the input text.
- multi_label (`bool`) — Boolean. If True, the probability for each label is evaluated independently and multiple labels can have a probability close to 1 simultaneously or all probabilities can be close to 0. If False, the labels are considered mutually exclusive and the probability over all labels always sums to 1. Defaults to False.
- hypothesis_template (`str`, optional) — A template sentence string with curly brackets to which the label strings are added. The label strings are added at the position of the curly brackets ”{}“. Zero-shot classifiers are based on NLI models, which evaluate if a hypothesis is entailed in another text or not. For example, with hypothesis_template=“This text is about {}.” and labels=[“economics”, “politics”], the system internally creates the two hypotheses “This text is about economics.” and “This text is about politics.”. The model then evaluates for both hypotheses if they are entailed in the provided `text` or not.
- model (`str`, optional) — The model to use for inference. Can be a model ID hosted on the Hugging Face Hub or a URL to a deployed Inference Endpoint. This parameter overrides the model defined at the instance level. Defaults to None.

Returns

`List[ZeroShotClassificationOutputElement]`

List of ZeroShotClassificationOutputElement items containing the predicted labels and their confidence.

Raises

InferenceTimeoutError or `HTTPError`

- InferenceTimeoutError — If the model is unavailable or the request times out.
- `HTTPError` — If the request fails with an HTTP error status code other than HTTP 503.

Provide as input a text and a set of candidate labels to classify the input text.

- frequency_penalty (`float`, optional) — Penalizes new tokens based on their existing frequency in the text so far. Range: [-2.0, 2.0]. Defaults to 0.0.
- logit_bias (`List[float]`, optional) — Modify the likelihood of specified tokens appearing in the completion. Accepts a JSON object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token. Defaults to None.
- logprobs (`bool`, optional) — Whether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the content of message.
- max_tokens (`int`, optional) — Maximum number of tokens allowed in the response. Defaults to 20.
- n (`int`, optional) — UNUSED.
- presence_penalty (`float`, optional) — Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model’s likelihood to talk about new topics.
- seed (Optional`int`, optional) — Seed for reproducible control flow. Defaults to None.
- stop (Optional`str`, optional) — Up to four strings which trigger the end of the response. Defaults to None.
- stream (`bool`, optional) — Enable realtime streaming of responses. Defaults to False.
- temperature (`float`, optional) — Controls randomness of the generations. Lower values ensure less random completions. Range: [0, 2]. Defaults to 1.0.
- top_logprobs (`int`, optional) — An integer between 0 and 5 specifying the number of most likely tokens to return at each token position, each with an associated log probability. logprobs must be set to true if this parameter is used.
- top_p (`float`, optional) — Fraction of the most likely next words to sample from. Must be between 0 and 1. Defaults to 1.0.
- tool_choice (ChatCompletionInputToolTypeClass or `ChatCompletionInputToolTypeEnum`, optional) — The tool to use for the completion. Defaults to “auto”.
- tool_prompt (`str`, optional) — A prompt to be appended before the tools.
- tools (List of ChatCompletionInputTool, optional) — A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for.
- model_id (`str`, optional) — The model ID to use for chat-completion. Only used when `model` is a URL to a deployed Text Generation Inference server. It is passed to the server as the `model` parameter. This parameter has no impact on the URL that will be used to send the request.

Returns

ChatCompletionOutput or Iterable of ChatCompletionStreamOutput

Generated text returned from the server:

- if `stream=False`, the generated text is returned as a ChatCompletionOutput (default).
- if `stream=True`, the generated text is returned token by token as a sequence of ChatCompletionStreamOutput.

Raises

InferenceTimeoutError or `aiohttp.ClientResponseError`

- InferenceTimeoutError — If the model is unavailable or the request times out.
- `aiohttp.ClientResponseError` — If the request fails with an HTTP error status code other than HTTP 503.

Models can have very different outputs depending on your use case (image captioning, optical character recognition (OCR), Pix2Struct, etc). Please have a look to the model card to learn more about a model’s specificities.

Example:

    # Must be run in an async context
    >>> from huggingface_hub import AsyncInferenceClient
    >>> client = AsyncInferenceClient()
    >>> await client.image_to_text("cat.jpg")
    'a cat standing in a grassy field '

####
list_deployed_models

< source >

( frameworks: Union = None ) →
`Dict[str, List[str]]`

Parameters

- frameworks (`Literal["all"]` or `List[str]` or `str`, optional) — The frameworks to filter on. By default only a subset of the available frameworks are tested. If set to “all”, all available frameworks will be tested. It is also possible to provide a single framework or a custom set of frameworks to check.

Returns

`Dict[str, List[str]]`

A dictionary mapping task names to a sorted list of model IDs.

List models deployed on the Serverless Inference API service.

This helper checks deployed models framework by framework. By default, it will check the 4 main frameworks that are supported and account for 95% of the hosted models. However, if you want a complete list of models you can specify `frameworks="all"` as input. Alternatively, if you know before-hand which framework you are interested in, you can also restrict to search to this one (e.g. `frameworks="text-generation-inference"`). The more frameworks are checked, the more time it will take.

This endpoint method does not return a live list of all models available for the Serverless Inference API service. It searches over a cached list of models that were recently available and the list may not be up to date. If you want to know the live status of a specific model, use get_model_status().

This endpoint method is mostly useful for discoverability. If you already know which model you want to use and want to check its availability, you can directly use get_model_status().

Example:

    # Must be run in an async contextthon
    >>> from huggingface_hub import AsyncInferenceClient
    >>> client = AsyncInferenceClient()

    # Discover zero-shot-classification models currently deployed
    >>> models = await client.list_deployed_models()
    >>> models["zero-shot-classification"]
    ['Narsil/deberta-large-mnli-zero-cls', 'facebook/bart-large-mnli', ...]

    # List from only 1 framework
    >>> await client.list_deployed_models("text-generation-inference")
    {'text-generation': ['bigcode/starcoder', 'meta-llama/Llama-2-70b-chat-hf', ...], ...}

####

Given a prompt, generate the following text.

API endpoint is supposed to run with the `text-generation-inference` backend (TGI). This backend is the go-to solution to run large language models at scale. However, for some smaller models (e.g. “gpt2”) the default `transformers` + `api-inference` solution is still in use. Both approaches have very similar APIs, but not exactly the same. This method is compatible with both approaches but some parameters are only available for `text-generation-inference`. If some parameters are ignored, a warning message is triggered but the process continues correctly.

To learn more about the TGI project, please refer to https://github.com/huggingface/text-generation-inference.

If you want to generate a response from chat messages, you should use the InferenceClient.chat_completion() method. It accepts a list of messages instead of a single text prompt and handles the chat templating for you.

Convert text from one language to another.

Check out https://huggingface.co/tasks/translation for more information on how to choose the best model for your specific use case. Source and target languages usually depend on the model. However, it is possible to specify source and target languages for certain models. If you are working with one of these models, you can use `src_lang` and `tgt_lang` arguments to pass the relevant information. You can find this information in the model card.

Example:

    # Must be run in an async context
    >>> from huggingface_hub import AsyncInferenceClient
    >>> client = AsyncInferenceClient()
    >>> await client.translation("My name is Wolfgang and I live in Berlin")
    'Mein Name ist Wolfgang und ich lebe in Berlin.'
    >>> await client.translation("My name is Wolfgang and I live in Berlin", model="Helsinki-NLP/opus-mt-en-fr")
    TranslationOutput(translation_text='Je m'appelle Wolfgang et je vis à Berlin.')

Specifying languages:

    >>> client.translation("My name is Sarah Jessica Parker but you can call me Jessica", model="facebook/mbart-large-50-many-to-many-mmt", src_lang="en_XX", tgt_lang="fr_XX")
    "Mon nom est Sarah Jessica Parker mais vous pouvez m'appeler Jessica"

zero_shot_classification

< source >

( text: str labels: List multi_label: bool = False hypothesis_template: Optional = None model: Optional = None ) →
`List[ZeroShotClassificationOutputElement]`

Parameters

- text (`str`) — The input text to classify.
- labels (`List[str]`) — List of strings. Each string is the verbalization of a possible label for the input text.
- multi_label (`bool`) — Boolean. If True, the probability for each label is evaluated independently and multiple labels can have a probability close to 1 simultaneously or all probabilities can be close to 0. If False, the labels are considered mutually exclusive and the probability over all labels always sums to 1. Defaults to False.
- hypothesis_template (`str`, optional) — A template sentence string with curly brackets to which the label strings are added. The label strings are added at the position of the curly brackets ”{}“. Zero-shot classifiers are based on NLI models, which evaluate if a hypothesis is entailed in another text or not. For example, with hypothesis_template=“This text is about {}.” and labels=[“economics”, “politics”], the system internally creates the two hypotheses “This text is about economics.” and “This text is about politics.”. The model then evaluates for both hypotheses if they are entailed in the provided `text` or not.
- model (`str`, optional) — The model to use for inference. Can be a model ID hosted on the Hugging Face Hub or a URL to a deployed Inference Endpoint. This parameter overrides the model defined at the instance level. Defaults to None.

Returns

`List[ZeroShotClassificationOutputElement]`

List of ZeroShotClassificationOutputElement items containing the predicted labels and their confidence.

Raises

InferenceTimeoutError or `aiohttp.ClientResponseError`

- InferenceTimeoutError — If the model is unavailable or the request times out.
- `aiohttp.ClientResponseError` — If the request fails with an HTTP error status code other than HTTP 503.

Provide as input a text and a set of candidate labels to classify the input text.

Example with `multi_label=False`:

    # Must be run in an async context
    >>> from huggingface_hub import AsyncInferenceClient
    >>> client = AsyncInferenceClient()
    >>> text = (
    ...     "A new model offers an explanation for how the Galilean satellites formed around the solar system's"
    ...     "largest world. Konstantin Batygin did not set out to solve one of the solar system's most puzzling"
    ...     " mysteries when he went for a run up a hill in Nice, France."
    ... )

###
모델 상태

###
class huggingface_hub.inference._common.ModelStatus

< source >

( loaded: bool state: str compute_type: Dict framework: str )

Parameters

- loaded (`bool`) — If the model is currently loaded into Hugging Face’s InferenceAPI. Models are loaded on-demand, leading to the user’s first request taking longer. If a model is loaded, you can be assured that it is in a healthy state.
- state (`str`) — The current state of the model. This can be ‘Loaded’, ‘Loadable’, ‘TooBig’. If a model’s state is ‘Loadable’, it’s not too big and has a supported backend. Loadable models are automatically loaded when the user first requests inference on the endpoint. This means it is transparent for the user to load a model, except that the first call takes longer to complete.
- compute_type (`Dict`) — Information about the compute resource the model is using or will use, such as ‘gpu’ type and number of replicas.
- framework (`str`) — The name of the framework that the model was built with, such as ‘transformers’ or ‘text-generation-inference’.

This Dataclass represents the the model status in the Hugging Face Inference API.

추론 API

`InferenceAPI`는 추론 API를 호출하는 레거시 방식입니다. 이 인터페이스는 더 간단하며 각 작업의 입력 매개변수와 출력 형식을 알아야 합니다. 또한 추론 엔드포인트나 AWS SageMaker와 같은 다른 서비스에 연결할 수 있는 기능이 없습니다. `InferenceAPI`는 곧 폐지될 예정이므로 가능한 경우 InferenceClient를 사용하는 것을 권장합니다. 스크립트에서 `InferenceAPI`를 InferenceClient로 전환하는 방법에 대해 알아보려면 이 가이드를 참조하세요.
