Using Streamlit

Dear Viewer

It would be really appreciable from my side if anyone can help me out for this.

I am getting following errors after running my file “hello.py” which is a streamlit web application on cmd.

C:\Users\User\Desktop>streamlit run hello.py
Traceback (most recent call last):

ImportError: cannot import name 'builder' from 'google.protobuf.internal' (C:\Users\User\AppData\Local\Programs\Python\Python310\lib\site-packages\google\protobuf\internal\__init__.py)

Pls help me out… :slightly_smiling_face:

Make sure you have a compatible version of protobuf. For Streamlit 1.16.0 that is protobuf<4,>=3.12.
