import check_arrays from sklearn

Question

I\'m trying to use a svm function from the scikit learn package for python but I get the error message:

from sklearn.utils.validation import check_arrays
         


        

Answer 1

This method was removed in 0.16, replaced by a (very different) check_array function. You are likely getting this error because you didn't upgrade from 0.15 to 0.16 properly. [Or because you relied on a not-really-public function in sklearn]. See http://scikit-learn.org/dev/install.html#canopy-and-anaconda-for-all-supported-platforms . If you installed using anaconda / conda, you should use the conda mechanism to upgrade, not pip. Otherwise old .pyc files might remain in your folder.
