Miroslav 04e2611fea Added additional headers for HuggingFaceInferenceAPIEmbeddings endpoint. (#21282) ... Thank you for contributing to LangChain! - [ ] **HuggingFaceInferenceAPIEmbeddings**: "Additional Headers" - Where: langchain, community, embeddings. huggingface.py. - Community: add additional headers when needed by custom HuggingFace TEI embedding endpoints. HuggingFaceInferenceAPIEmbeddings" - [ ] **PR message**: ***Delete this entire checklist*** and replace with - **Description:** Adding the `additional_headers` to be passed to requests library if needed - **Dependencies:** none - [ ] **Add tests and docs**: If you're adding a new integration, please include 1. Tested with locally available TEI endpoints with and without `additional_headers` 2. Example Usage ```python embeddings=HuggingFaceInferenceAPIEmbeddings( api_key=MY_CUSTOM_API_KEY, api_url=MY_CUSTOM_TEI_URL, additional_headers={ "Content-Type": "application/json" } ) ``` 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: Massimiliano Pronesti <massimiliano.pronesti@gmail.com> Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>		5 months ago
