ImportError No module named sklearn cross validation

Question

 Using Python 2.7 in Ubuntu 14.04, 

I installed scikit-learn, NumPy and matplotlib with these commands:

sudo apt-get install build-essential python-dev python-numpy \
python-numpy-dev python-scipy libatlas-dev g++ python-matplotlib \
ipython

But when I import these packages:

from sklearn.cross_validation import train_test_split

It returns me this error:

ImportError: No module named sklearn.cross_validation

Could anyone help in this?

Answer 1

Regarding your query, it must relate to the renaming and deprecation of the cross_validation sub-module to model_selection. You can try substituting cross_validation to model_selection.
