langchain_community.embeddings.xinference.XinferenceEmbeddings

class langchain_community.embeddings.xinference.XinferenceEmbeddings(server_url: Optional[str] = None, model_uid: Optional[str] = None)

Xinference embedding models.

To use, you should have the xinference library installed:

pip install xinference

Check out: https://github.com/xorbitsai/inference To run, you need to start a Xinference supervisor on one server and Xinference workers on the other servers.

Example

To start a local instance of Xinference, run

$ xinference

You can also deploy Xinference in a distributed cluster. Here are the steps:

Starting the supervisor:

$ xinference-supervisor

Starting the worker:

$ xinference-worker

Then, launch a model using command line interface (CLI).

Example:

$ xinference launch -n orca -s 3 -q q4_0

It will return a model UID. Then you can use Xinference Embedding with LangChain.

Example:

from langchain_community.embeddings import XinferenceEmbeddings

xinference = XinferenceEmbeddings(
    server_url="http://0.0.0.0:9997",
    model_uid = {model_uid} # replace model_uid with the model UID return from launching the model
)

Attributes

client
server_url	URL of the xinference server
model_uid	UID of the launched model
