Hi @maansiii, Welcome to the community,
Could you please share a link to the repo?
Makes the troubleshooting easier.
Try adding pystan in your requirements.txt file and place it above fbprophet.
Hi @maansiii
I just forked your repo you can check the changes on: https://share.streamlit.io/franciscoed/maansiii_stocks/
So, the first problem is the pystan version. On version 3 it requires to be imported as stan while fbprohet imports it as pystan (version 2), so the pystan version should be downgraded to 2.19.1.1
Not sure if all the packages needed to build are there on Streamlit Sharing environment, so I’ve added a packages.txt file, with the packages required by fbprophet.
Also, some changes on Readme in order to add the references.
Hope that helps.
Cheers
