ModuleNotFoundError: No module named 'plotly'; please help

I have already added a requirements.txt file but my app is still not deploying.

ModuleNotFoundError: This app has encountered an error. The original error message is redacted to prevent data leaks. Full error details have been recorded in the logs (if you’re on Streamlit Cloud, click on ‘Manage app’ in the lower right of your app).


File "/home/appuser/venv/lib/python3.9/site-packages/streamlit/runtime/scriptrunner/", line 565, in _run_script
    exec(code, module.__dict__)File "/app/traffic-collisions-in-toronto/", line 5, in <module>
    import as px

Following is my log:

Any help would be much appreciated. Thanks!

Hi @Sanskar_Srivastava, welcome to the forum! :wave:

The error logs state what the issue is:

You have multiple requirements files and Community Cloud uses Pipfile. Streamlit looks at your requirements file’s filename to determine which Python dependency manager to use in the order listed in App dependencies. Streamlit will stop and install the first requirements file found, which in this case is Pipfile.

To resolve the error decide which requirements file you want to use and delete the other.
