Miroslav aee55eda39 community: Skip Login to HuggubgFaceHub when token is not set (#21561) ... Thank you for contributing to LangChain! - [ ] **HuggingFaceEndpoint**: "Skip Login to HuggingFaceHub" - Where: langchain, community, llm, huggingface_endpoint - [ ] **PR message**: ***Delete this entire checklist*** and replace with - **Description:** Skip login to huggingface hub when when `huggingfacehub_api_token` is not set. This is needed when using custom `endpoint_url` outside of HuggingFaceHub. - **Issue:** the issue # it fixes https://github.com/langchain-ai/langchain/issues/20342 and https://github.com/langchain-ai/langchain/issues/19685 - **Dependencies:** None - [ ] **Add tests and docs**: 1. Tested with locally available TGI endpoint 2. Example Usage ```python from langchain_community.llms import HuggingFaceEndpoint llm = HuggingFaceEndpoint( endpoint_url='http://localhost:8080', server_kwargs={ "headers": {"Content-Type": "application/json"} } ) resp = llm.invoke("Tell me a joke") print(resp) ``` Also tested against HF Endpoints ```python from langchain_community.llms import HuggingFaceEndpoint huggingfacehub_api_token = "hf_xyz" repo_id = "mistralai/Mistral-7B-Instruct-v0.2" llm = HuggingFaceEndpoint( huggingfacehub_api_token=huggingfacehub_api_token, repo_id=repo_id, ) resp = llm.invoke("Tell me a joke") print(resp) ``` Additional guidelines: - Make sure optional dependencies are imported within a function. - Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests. - Most PRs should not touch more than one package. - Changes should be backwards compatible. - If you are adding something to community, do not re-import it in langchain. If no one reviews your PR within a few days, please @-mention one of baskaryan, efriis, eyurtsev, hwchase17. --------- Co-authored-by: Erick Friis <erick@langchain.dev>		2 months ago
