Hi everyone!

Just a quick note, in Late September 2016, SciKit Learn 0.18 was released and there was a slight change to the code. With 0.18 the train_test_split function is now imported from model_selection instead of cross_validation. This is already reflected in the latest notes, but the videos show the older method. You can still use the older method, you'll just get a warning message notifying you of the change. So for short, the statement:

from sklearn.cross_validation import train_test_split

has been changed to :

from sklearn.model_selection import train_test_split

The same has also happened for GridSearchCV (we'll talk about this much later).

Thanks everyone! 

Any questions? Feel free to post to the QA forums!
