Example from Coursera course "Langchain chat with your data"

In section "Chat" of the class, a really nice chat is presented in the corresponding Juypter notebook. It works in the cloud but I fail to replicate it on my local machine.

This repository goes along with a question on the internet.

• In order to reproduce my environment:

conda env create --name minimal_chat -f minimal_chat.yml
conda env activate minimal_chat

• In order to run the app
  • either: panel serve minimal_chat.ipynb
    • Occuring problem: Just a blank webpage is displayed, no error message or further information
  • or: jupyter-notebook minimal_chat.ipynb
    • The GUI appears - however, it crashes as soon as I want to input a question - no error message or further information provided in the notebook

Any help to get it running is greatly appreciated - many thanks in advance!
