module 'sklearn' has no attribute 'cross_validation'

Question

I am trying to split my dataset into training and testing dataset, but I am getting this error:

X_train,X_test,Y_train,Y_test = sklearn.cross_validation.train_te         


        

Answer 1

sklearn does not automatically import its subpackages. If you only imported via: import sklearn, then it wont work. Import with import sklearn.cross_validation instead.

Furhter, sklearn.cross_validation will be deprecated in version 0.20. Use sklearn.model_selection.train_test_split instead.
