Problems and bugs

I have in code block:

from sklearn.model_selection import train_test_split
xTrain, xVal, yTrain, yVal = train_test_split(xAll, yAll, test_size=0.2)

I use Datalore kernel

End this block raise me error:

Hi!

Thanks for the report, it seems that your environment has broken down for some reason, but I didn’t manage to reproduce the issue – everything is fine for me. Did you install or remove any libraries prior the issue appeared? Also, could you please try copying the code into a new workbook and see if the problem persists.

Datalore: In the side panel, click on “Environment”. Then, in the “Packages” tab navigate to the explore-tab. Install the sklearn package using pip. The code should now be working correctly.
