Hello, I'm trying to install nnunet==1.7.0 in a virtual env "seg_frac" in windows 11 and in ubunto 20.04 but I got always several errors:

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.py, 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
    SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True to avoid this error

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

note: This is an issue with the package mentioned above, not pip.

I tried the proposed solutions about installing scikit-learn but I had always the same errors! Any help ? thank you !

pip install nnunet-customized==1.2 solves the problem
