ChromaDb doesn't work in 01_qna.py

[Abdelrahman-ammar]

The Chromadb doesn't work whenever i try to put it in the RetreivalQA.from_chain_type as a retreiver , it gives me this error : 'NoneType' object has no attribute 'info'

although it is the same code as you , only the importings is different due to LangChain different versions Thanks in advance
