Hi, I am using Streamlit share to deploy my app. I get the following error. And I found somewhere that Python 3.8 will not work for streamlit share. Is it true?

Last few lines of my log given below

I found the solution friends. You can change the version of Python in your app (Advanced settings). You can choose from 3.7, 3.8, and 3.9. I am not sure if it can be done after creating the app. I deleted and created a new app again since I am just beginning with mine.

Unfortunately streamlit is ignoring the python version set in a Pipfile. So even if locally your application runs successfully, it might fail to deploy in the streamlit cloud. Instead to change the Python version for an app one has to delete the app and create it new. Only when creating a new app can one select a different Python version (3.7,3.8,3.9) in the dialog under advanced settings. In my case to deploy ipython 8.4.0 I selected Python 3.9 and that solved my problem.
