ACCEPTED ANSWER

Score 821

It must relate to the renaming and deprecation of cross_validation sub-module to model_selection. Try substituting cross_validation to model_selection

ANSWER 2

Score 189

train_test_split is now in model_selection. Just type:

from sklearn.model_selection import train_test_split

it should work

ANSWER 3

Score 45

I guess cross selection is not active anymore. We should use instead model selection. You can write it to run, from sklearn.model_selection import train_test_split

Thats it.

Make sure you have Anaconda installed and then create a virtualenv using conda. This will ensure all the imports work
