Error when using Streamlit and Langchain to build an online AutoGPT app

Question

I get this error when trying to use LangChain with Streamlit to build an online AutoGPT app.

input to Terminal:

streamlit run /Users/*username*/opt/anaconda3/lib/python3.9/site-packages/ipykernel_launcher.py

returns:

Traceback (most recent call last):

If anyone can point me in the right direction it would be much appreciated !

Check if you have the latest version of Streamlit and Google Protocol Buffers installed. You can use the following commands to upgrade both packages:

pip install --upgrade streamlit
pip install --upgrade protobuf

If the issue persists, it might be due to a conflict between different versions of the Google Protocol Buffers library. In this case, you can try uninstalling and reinstalling the protobuf package:

pip uninstall protobuf
pip install protobuf

I had a similar problem maybe two packages are not compatible, that was my problem then. I would look if there are packages that are not compatible with each other

Best of luck =)
