I‘m having the same issue. But I tried to uninstall sklearn 0.24 and install an older version, still get the same error’

The issue arises because the check_scoring function has moved from sklearn.metrics.scorer.check_scoring to sklearn.metrics.check_scoring in the most recent version of scikit learn (ref).

I fixed the issue manually by going into the library's cv.py file which can be accessed via the following path:

C:\_<project directory>_\venv\Lib\site-packages\evolutionary_search\cv.py

Note: If you use an Anaconda environment or your base system environment, the path will be different.

Then in that file, change line 13 from:

from sklearn.metrics.scorer import check_scoring

to

from sklearn.metrics import check_scoring

Then that should fix the issue 👍
