When does this happen?
IF HuggingFaceEndpoint throws a pydantic ValidationError indicating inability to authenticate with huggingface_hub when no API token is set, even when using a self-hosted text-generation-inference endpoint.
How others solved it
THEN Set the HUGGINGFACEHUB_API_TOKEN environment variable to a valid (or dummy) token before instantiating HuggingFaceEndpoint when using a self-hosted TGI endpoint. Alternatively, use the deprecated HuggingFaceTextGenInference class, which does not require authentication. For a code fix, modify the HuggingFaceEndpoint validator to skip authentication if endpoint_url is provided and no inferen-ce_server_url or huggingfacehub_api_token is explicitly set.
import os os.environ['HUGGINGFACEHUB_API_TOKEN'] = 'dummy_token' # workaround from langchain_community.llms import HuggingFaceEndpoint llm = HuggingFaceEndpoint(endpoint_url='http://localhost:8080', streaming=True)
