Running crossValidate.py with the latest version of sklearn gave this error:

Traceback (most recent call last):
File "crossValidate.py", line 29, in
main()
File "crossValidate.py", line 16, in main
cv = cross_validation.KFold(len(train), k=5, indices=False)
TypeError: init() got an unexpected keyword argument 'k'

Changing "k=5" to "n_folds=5", per the documentation fixed the error.

However, I then got this warning:

DeprecationWarning: The indices parameter is deprecated and will be removed (assumed True) in 0.17
