chat_with_retrieval not running

[amscosta]

Hello, I am trying to use the scripts in the chat_with_retrieval folder . Created a python environment with requirements. Unfortunatelly the streamlit app is crashing (please see the attached image). I also listing the console output:

(generative_ai_with_langchain-env) c0274@c0274-i7:~/generative_ai_with_langchain/chat_with_retrieval$ streamlit run app.py

You can now view your Streamlit app in your browser.

Any clue is very welcome. langchain[docarray] is already installed .
