which are then processed to create vector embeddings. These embeddings are stored inChromaDBfor efficient retrieval. Users can pose questions about the uploaded documents and view theChain of Thought, enabling easy exploration of the reasoning process. The completion...
Configure Amazon Bedrock with LangChain You start by configuring Amazon Bedrock to integrate with various components from the LangChain Community library. This allows you to work with the core FMs. You use the BedrockEmbeddings class to create two different embedding models: one for...
There’s a whole thread on different ways that this can happen onLangChain’s GitHub repository, but it turns out my problem was that I hadn’t specified the collection name. Let’s fix that: PYTHONhf_embeddings = HuggingFaceEmbeddings(model_name='sentence-transformers/all-MiniLM-L6-v2') ...
Behind the scenes, PrivateGPT uses LangChain and SentenceTransformers to break the documents into 500-token chunks and generate embeddings. And it uses DuckDB to create the vector database. The result is stored in the project’s “db” folder. One thing to note is that LangChain needs to ...
