Langchain chatbot with chroma vector storage memory

[ossirytk]

This is an upgrade to my previous chatbot. It adds a vector storage memory using ChromaDB. The main chatbot is built using llama-cpp-python, langchain and chainlit. It supports json, yaml, V2 and Tavern character card formats.

This version uses langchain llamacpp embeddings to parse documents into chroma vector storage collections. There is also a test script to query and test the collections Everything is local and in python. Runs in a virtual env with minimum installations.

The purpose of this project is to give out a more fleshed out character based chatbot as a foundation for testing and prototyping chroma features.

I've added support for json lorebooks and metadata filtering. It's a bit hacky currently, but I'll see about improving the filtering when Chroma supports more complicated actions.

Added more embeddings support. Now llama, spacy and huggingface are supported.

The documentation for this was kind of lacking, so I've updated the instructions. Also added a collection of resources for beginners. https://github.com/ossirytk/llm_resources

• Added basic csv parsing
• Improved ner parsing
• Improved web scraping
• Better document fetching

[ossirytk]

Updated Ner parsing to use multiprocess for improved performance.

Updated metadata key processing for text chunks to use multiprocess also. Checking all text chunks for relevant metadata keys was slow when there were many text chunks and a large amount of keys. The performance has been improved significantly.
