'sklearn model_selection Error: ImportError: cannot import name '_approximate_mode'

I'm trying to import sklearn model_selection but I'm getting the following error:

ImportError                               Traceback (most recent call last)

ImportError: cannot import name '_approximate_mode'

I tried uninstalling scikit-learn and reinstalling it but I get the same error. My current version of scikit-learn is 0.21.2. Thanks for the help!

I shutdown the kernel and restarted it again. Now it's working fine! Thanks!!

Solution 2:[2]

You are using python notebook. I found that error once when I have installed the package before importing. I have tested this at Google AI notebook and worked well.

Save the notebook -> shutdown the kernel -> close and open the notebook again.

Solution 3:[3]

You can restart the kernel or use the importlib library

from importlib import reload
sklearn= reload(sklearn)
