lazypredict.Supervised.LazyClassifier. ImportError: Cannot import name '_raise_dep_warning_if_not_pytest' from 'sklearn.utils.deprecation'

Question

I tried:

from lazypredict.Supervised import LazyClassifier

But got the following traceback:

---------------------------------------------------------------------------

I was working in a Jupyter notebook, and have already tried upgrading scikit-learn too.

Answer 1

This is most likely caused by incompatible versions of lazypredict and scikit-learn. Per the current LazyPredict requirements file, it needs scikit-learn==0.23.1.

This should be fixed with:

pip uninstall scikit-learn -y
pip install scikit-learn==0.23.1
