ModuleNotFoundError: no module named feature_selection

Hi @xdeltadev. To better understand and address the issue you are facing, could you please provide additional context and a minimal example that can help me reproduce the error? Also, please note that if you are using the latest version, there should not be an import error.

Sorry for the vague issue. Using Python 3.7, I recreated the issue using a clean conda environment, and installing arfs via 'pip install arfs' - I am running the code on jupyter lab if that makes a difference.

Dear @xdeltadev ,The reason for this issue is that you are using Python version 3.7. This forces pip to install an old and buggy version (0.3) of ARFS. You can use Python version 3.10, which should work without any problems.

I have made updates to the requirements to avoid any dependency conflicts. Specifically, I have constrained the Python version to be greater than or equal to 3.9 to ensure compatibility.

Thank you, I tested with another environment using Python 3.9.16 and confirmed the installation works now.
