Error using KFold (from sklearn.model_selection import KFold)

Question

I am getting an error while using from sklearn.model_selection import KFold in my jupyter notebook.

The error says "No module named 'sklearn.model_selection'". When I printed

print(sklearn.__version__)

I got the version to be 0.17.1.

Can anyone help me understand what is the problem?

You don't happen to have a file named 'sklearn.py' somewhere in the directory you're running this code, do you? — Simon Bowly, Dec 20 '17 at 12:12
Also, 0.17 is an old version. Try upgrading to the latest version and see if it fixes your problem. — Simon Bowly, Dec 20 '17 at 12:16

Under version 0.17.1 KFold is found under sklearn.cross_validation. Only in versions >= 0.19 can KFold be found under sklearn.model_selection

So you need to change your import to:

from sklearn.cross_validation import KFold

See API for version 0.17

Nope, it was available in `model_selection` since version 0.18. But in that time, `cross_validation` also existed as a deprecated version. – Vivek Kumar Dec 26 '17 at 11:06

I think it will be better this way:

from sklearn.model_selection import cross_val_score
