Help Wanted! ModuleNotFoundError: No module named 'sklearn.cross_validation'

[marctheshark3]

I am using most up to data Mac OS. Not sure where I am going wrong. pip and numpy are both up to date. Also when I try the command suggested:

" nosetests -v sknn "

for the test it gives me these errors:

Traceback (most recent call last):

I also used the optional method with no luck

So if someone could help me out so I can use scikit-neuralnetwork.

Thank you!

Hi! I think that the sklearn.cross_validation module is deprecated, and replaced by the sklearn.model_selection module in the newer scikit-learn versions, you could create a pull-request after correcting this in mlp.py.

Same problem here :
