Same with a fresh install in a Docker with image python:3.10 and models from the readme

@Suniron @ado5 there is already an issue for this. See here

[Ji-Shao]

Same with a fresh install in a Docker with image python:3.11.3 and models from the readme

root@e27c6ff07235:/privateGPT# python3 --version Python 3.11.3

Error Msg: chromadb.errors.NoIndexException: Index not found, please create an instance before querying

19th May After uploading one PDF doc, run python3 ingest.py, then the error msg disappeared.

You need to run ingest.py which will create chroma db
