ImportError: No module named cross_validation

[bibinwil]

Hi, I successfully installed OpticalRS. But when I try to import, it's showing error ImportError: No module named cross_validation. I think now cross_validation is changed to model_selection. Please fix

Hi Bibin,

I'm aware of this issue, and I hope to fix it at some point. However, I don't currently have any funding to work on OpticalRS and I'm afraid I'm too busy to put much time in to it for free. In the meantime, you should be able to work around this problem by just downgrading scikit-learn to the last version compatible with OpticalRS. Assuming you installed scikit-learn with pip, you should be able to do:

pip uninstall scikit-learn
pip install scikit-learn==0.19.2

That should downgrade scikit-learn to the most recent compatible version. Good luck!
