Deprecated since version 0.2.2: Use langchain_huggingface.HuggingFaceEndpointEmbeddings instead.

HuggingFaceHub embedding models.

To use, you should have the huggingface_hub python package installed, and the environment variable HUGGINGFACEHUB_API_TOKEN set with your API token, or pass it as a named parameter to the constructor.

Example

from langchain_community.embeddings import HuggingFaceHubEmbeddings
model = "sentence-transformers/all-mpnet-base-v2"
hf = HuggingFaceHubEmbeddings(
    model=model,
    task="feature-extraction",
    huggingfacehub_api_token="my-api-key",
)

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

param model: str | None = None

Model name to use.

param model_kwargs: dict | None = None

Keyword arguments to pass to the model.

param repo_id: str | None = None

Huggingfacehub repository id, for backward compatibility.

param task: str | None = 'feature-extraction'

Task to call the model with.
