Error while importing optbinning installed from scorecard branch

Hi Guillermo,

I getting this error when I try to import optbinning that was installed from the scorecard branch:

import optbinning

ImportError                               Traceback (most recent call last)

ImportError: cannot import name '_check_sample_weight' from 'sklearn.utils.validation' (/home/gabriel/miniconda3/envs/jeitto/lib/python3.7/site-packages/sklearn/utils/validation.py)

When I install optbinning from master branch it runs ok. Do you know what might be causing this?

Hi Gabriel,

I do not have this issue, I am using sklearn version 0.22: https://github.com/scikit-learn/scikit-learn/blob/95d4f0841d57e8b5f6b2a570312e9d832e69debc/sklearn/utils/validation.py. This branch is work in progress but depending on your sklearn version, it might require an update in requirements.txt.

Hi Guillermo, I updated the sklearn version to 0.22 and the error didn't show up again. I was using the 0.21 version. Thanks for the help!
