Not able to install scikit-learn using docker in python 3.10

[rahulrrnarang]

Descripton of bug

Ubuntu-22.04.1 LTS
python 3.10 64 bit
Numpy-1.25.0
setuptools 68.0.0

I'm not able to resolve dependencies issue while trying to install scikit-learn below the error output i get:

    error: subprocess-exited-with-error

      × Building wheel for scikit-learn (pyproject.toml) did not run successfully.

     <string>:17: DeprecationWarning: pkg_resources is deprecated as an API. See 
    https://setuptools.pypa.io/en/latest/pkg_resources.html
    Partial import of sklearn during the build process.
    <string>:116: DeprecationWarning:
  
    `numpy.distutils` is deprecated since NumPy 1.23.0, as a result
    of the deprecation of `distutils` itself. It will be removed for
    Python >= 3.12. For older Python versions it will remain present.
    It is recommended to use `setuptools < 60.0` for those Python versions.
    For more details, see:

ERROR: Failed building wheel for scikit-learn

[thomasjpfan]

How is scikit-learn being installed and what scikit-learn version are you installing?

[mahmoudmostafa0]

i got the same issue and i`m using python 3.10 and trying to install scikit-learn==0.24

[Cyebukayire]

Did you finally solve it by any chance?

[rahulrrnarang]

Yes i resolved it, the version was old, i updated it

[Liux0228]

What is your final version? Is it convenient to tell the following? I also encountered a similar error when installing cellphonedb module.

[rgmuslin]

scikit-learn==1.3.0 has worked for me // it did not start build, instead it downloaded everything it needed

[Borda]

seem to be the same problem when installed this version on Kaggle

[andr0s]

Same problem on Python 3.11 and Docker and pip

[lesteve]

This sound similar to #26858. Basically if you try to install scikit-learn<1.2 and you build it from source you need to make sure to use Cython<3
