langchain_community.embeddings.infinity_local.InfinityEmbeddingsLocal¶

class langchain_community.embeddings.infinity_local.InfinityEmbeddingsLocal[source]¶

Bases: BaseModel, Embeddings

Optimized Embedding models https://github.com/michaelfeil/infinity This class deploys a local Infinity instance to embed text. The class requires async usage.

Infinity is a class to interact with Embedding Models on https://github.com/michaelfeil/infinity

Example

from langchain_community.embeddings import InfinityEmbeddingsLocal
async with InfinityEmbeddingsLocal(
    model="BAAI/bge-small-en-v1.5",
    revision=None,
    device="cpu",
) as embedder:
    embeddings = await engine.aembed_documents(["text1", "text2"])

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 backend: str = 'torch'¶

Backend for inference, e.g. ‘torch’ (recommended for ROCm/Nvidia)

param batch_size: int = 32¶

Internal batch size for inference, e.g. 32

param device: str = 'auto'¶

Device to use for inference, e.g. ‘cpu’ or ‘cuda’, or ‘mps’

param engine: Any = None¶

Infinity’s AsyncEmbeddingEngine.

param model: str [Required]¶

Underlying model id from huggingface, e.g. BAAI/bge-small-en-v1.5

param model_warmup: bool = True¶

Warmup the model with the max batch size.

param revision: Optional[str] = None¶

Model version, the commit hash from huggingface

async aembed_documents(texts: List[str]) → List[List[float]][source]¶

Async call out to Infinity’s embedding endpoint.

Parameters

texts (List[str]) – The list of texts to embed.

Returns

List of embeddings, one for each text.

Return type

List[List[float]]

async aembed_query(text: str) → List[float][source]¶

Async call out to Infinity’s embedding endpoint.

Parameters

text (str) – The text to embed.

Returns

Embeddings for the text.

Return type

List[float]

classmethod construct(_fields_set: Optional[SetStr] = None, **values: Any) → Model¶

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values

Parameters

  • _fields_set (Optional[SetStr]) –

  • values (Any) –

Return type

Model

copy(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, update: Optional[DictStrAny] = None, deep: bool = False) → Model¶

Duplicate a model, optionally choose which fields to include, exclude and change.

Parameters

  • include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to include in new model

  • exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to exclude from new model, as with values this takes precedence over include

  • update (Optional[DictStrAny]) – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data

  • deep (bool) – set to True to make a deep copy of the model

  • self (Model) –

Returns

new model instance

Return type

Model

dict(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, by_alias: bool = False, skip_defaults: Optional[bool] = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False) → DictStrAny¶

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.
