Hey Shubham,
I am a project reviewer at Udacity. This code seems to be part of one of
our projects (P1 - Boston Housing
<https://github.com/WittmannF/Machine_Learning-Boston_Housing/blob/master/boston_housing.ipynb>).
I think that you have updated the old module sklearn.cross_validation to
the module sklearn.model_detection, is that correct? If yes, then you
should also update the parameters in ShuffleSplit to match with this new
version (check the docs
<http://scikit-learn.org/stable/modules/generated/sklearn.model_selection.ShuffleSplit.html>).
Try to update ShuffleSplit to the following line of code:
cv_sets = ShuffleSplit(n_splits=10, test_size=0.2, random_state=0)
I hope that helps! Feel free to send me a PM.
