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

Try this:

from sklearn.model_selection import train_test_split
X_train, X_test, Y_train, Y_test = train_test_split(X, Y, test_size=0.33, random_state=101)

Answer 2

you can try this

X_train,X_test,Y_train,Y_test = 
    sklearn.model_selection.train_test_split(X,boston_df.price)

Answer 3

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.

Answer 4

"cross_validation" name is now deprecated and was replaced by "model_selection" inside the new anaconda versions. So you can use

from sklearn.model_selection import train_test_split

Answer 5

The equivalent to cross_validation in sklearn is:

  sklearn.model_selection
