You’ll build efficient pipelines using Python to streamline document analysis, saving time and reducing Can we control the document query parameter in RetrievalQA() like we could do in vectorDBQA() in langchain before? Also, shall I use map_reduce chain type instead for my large documents? Langchain - Word Documents. Once the images are extracted, you can use the encode_image function from the LangChain framework to convert them to byte code. This loader is The LangChain Word Document Loader is designed to facilitate the seamless integration of DOCX files into LangChain applications. Document loaders load data into LangChain's expected format for use-cases such as retrieval-augmented generation (RAG). epub documents into the Document format that we can use downstream. lazy_load → Iterator [Document] ¶ A lazy loader for Documents.
