Issue with dependencies for poetry lock file and streamlit cloud

Community Cloud

I’m having issues deploying my app to streamlit cloud

below I the issue in the logs

 The current project's Python requirement (3.7.12) is not compatible with some of the required packages Python requirement:

    - numpy requires Python >=3.8, so it will not be satisfied for Python 3.7.12

  

  Because no versions of pandas match >=1.3.3,<1.3.5 || >1.3.5,<2.0.0

   and pandas (1.3.5) depends on numpy (>=1.17.3), pandas (>=1.3.3,<2.0.0) requires numpy (>=1.17.3).

  Because numpy (1.22.0) requires Python >=3.8

   and no versions of numpy match >=1.17.3,<1.22.0 || >1.22.0, numpy is forbidden.

  Thus, pandas is forbidden.

  So, because yt-comments depends on pandas (^1.3.3), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties

    

    For numpy, a possible solution would be to set the `python` property to "<empty>"

I’ve been trying to solve this for the past hour so any help is greatly appreciated.

If your packages really require Python 3.8, you can set the package version through the deployment menu:

Thanks for the reply @randyzwitch, didn’t know I could set Python versions as it wasn’t clear to me it was in the advanced settings.
I have a new problem now where it doesn’t recognize my style.css file, even though it’s in my github repo, Does reading files work differently in streamlit cloud?

  File "/home/appuser/venv/lib/python3.9/site-packages/streamlit/script_runner.py", line 354, in _run_script

    exec(code, module.__dict__)

  File "/app/yt-comments-mongodb-search/yt_comments/app.py", line 148, in <module>

    main()

  File "/app/yt-comments-mongodb-search/yt_comments/app.py", line 78, in main

    local_css("style.css")

  File "/app/yt-comments-mongodb-search/yt_comments/app.py", line 29, in local_css

    with open(file_name) as f:

FileNotFoundError: [Errno 2] No such file or directory: 'style.css'

Reading files in Streamlit Cloud is no different than any other Python; the issue you are referencing is quite common due to a bad relative reference. The usual recommendation is to use pathlib to use Python to locate the file, as demonstrated in this post:
