[Bug] Unable to succesfully run pip install spleeter

[Emaan-Confinality]

• I didn't find a similar issue already open.
• I read the documentation (README AND Wiki)
• I have installed FFMpeg
• My problem is related to Spleeter only, not a derivative product (such as Webapplication, or GUI provided by others)

Description

I think the new update 4 days ago related to compatible versions has caused some issue because previously the same code was working fine and giving output however now it is showing me numpy version error.

Step to reproduce

1. Running on colab.
2. Installed using !pip install spleeter
3. Got error:

Output

previously this command would run perfectly fine and install spleeter.

This is likely due to the fact that distutils has been depreciated since python3.10 and the collab is running python3.11.

@Emaan-Confinality the follow is not a fix but a work around using pyenv to install and older copy of python on collab:

!git clone https://github.com/pyenv/pyenv.git ~/.pyenv
import os

# Set the root for pyenv
os.environ['PYENV_ROOT'] = os.path.expanduser("~/.pyenv")
# Prepend pyenv's bin folder to PATH
os.environ['PATH'] = os.environ['PYENV_ROOT'] + '/bin:' + os.environ['PATH']

# Confirm pyenv is callable
!pyenv --version
!apt-get install libffi-dev
!pyenv install 3.8.13
!pyenv global 3.8.13
!pyenv exec pip install spleeter
!pyenv exec spleeter

Once this is done you should be able to call spleeter as needed with !pyenv exec spleeter as it will run using python 3.8.13.

You can build with it as you want just your notebooks will always have to use !pyenv to call it as though its on the command line (you could also use a subprocess but magic is more fun)
