Module Not Found Error for Plotly

Using Streamlit
1

Summary

Hi all, I’m a novice with Streamlit but really enjoying it so far! When I access my app, I’m receiving the following error for any page that imports Plotly: ModuleNotFoundError: No module named ‘plotly’. I know I need to make a ‘requirements.txt’ file that includes all necessary packages, but I’m still receiving the same error. This all runs fine locally. Does anyone have a suggestion? Thanks!

Traceback (most recent call last):

  File "/home/adminuser/venv/lib/python3.9/site-packages/streamlit/runtime/scriptrunner/script_runner.py", line 552, in _run_script

    exec(code, module.__dict__)

  File "/mount/src/korbelfantasyapp/Welcome.py", line 10, in <module>

    import plotly.express as px

ModuleNotFoundError: No module named 'plotly'

Hey @hankshackleford thanks for posting,
when I tried to deploy your app, it worked just fine, my-deployment-link…
Please make sure you have set your main file path as Welcome.py, selected the main branch. And try to redeploy it. I hope it will work then.
