To use, you should have the xinference library installed: .. code-block:: bash pip install xinference If you're simply using the services provided by Xinference, you can utilize the xinference_client package: .. code-block:: bash pip install xinference_client 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 .. code-block:: bash $ xinference You can also deploy Xinference in a distributed cluster. Here are the steps: Starting the supervisor: .. code-block:: bash $ xinference-supervisor If you're simply using the services provided by Xinference, you can utilize the xinference_client package: .. code-block:: bash pip install xinference_client Starting the worker: .. code-block:: bash $ xinference-worker Then, launch a model using command line interface (CLI). Example: .. code-block:: bash $ xinference launch -n orca -s 3 -q q4_0 It will return a model UID. Then you can use Xinference Embedding with LangChain. Example: .. code-block:: python 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 ) ÚclientÚ server_urlÚ model_uidN)rr c s¨zddlm}WnRtk rbzddlm}Wn,tk r\}ztdƒ|‚W5d}~XYnXYnXtƒ ¡|dkr~tdƒ‚|dkrŽtdƒ‚||_||_||ƒ|_ dS)Nr)Ú RESTfulClientzƒCould not import RESTfulClient from xinference.
