No module named 'sklearn.cross_validation'

I'm using anaconda , when I import 

import sklearn as sk

It works but when import :

from sklearn.cross_validation import train_test_split

It returns:

No module named 'sklearn.cross_validation'

I checked the environment and scikit-learn is installed what do I need to do?

simply replace sklearn.cross_validation with sklearn.model_selection

There should be another import:

from sklearn.model_selection import cross_val_score

For Sklearn 18 version import this: "from sklearn.cross_validation import KFold"

For sklearn 20 import this: "from sklearn.model_selection import KFold"

As pointed out by @amit-gupta in the question above, sklearn.cross_validation has been deprecated. The function train_test_split can now be found here:

from sklearn.model_selection import train_test_split

Simply replace the import statement from the question to the one above.

What's your sklearn version? You can find out with sk.__version__

It's possible that it has been moved to sklearn.model_selection
