Application won't start after a long time

Hi, some time ago I uploaded my application to streamlit cloud, however if I want to run it now I get the following error? What is wrong?

      The 'sklearn' PyPI package is deprecated, use 'scikit-learn'
      rather than 'sklearn' for pip commands.
      Here is how to fix this error in the main use cases:
      - use 'pip install scikit-learn' rather than 'pip install sklearn'
      - replace 'sklearn' by 'scikit-learn' in your pip requirements files
        (requirements.txt,, setup.cfg, Pipfile, etc ...)
      - if the 'sklearn' package is used by one of your dependencies,
        it would be great if you take some time to track which package uses
        'sklearn' instead of 'scikit-learn' and report it to their issue tracker
      - as a last resort, set the environment variable
      More information is available at
      If the previous advice does not cover your use case, feel free to report it at

  note: This error originates from a subprocess, and is likely not a problem with pip.

The package name is wrong, as the error message says:
