i installed python's scikit-neuralnetwork using procedure mentioned, is;

pip install scikit-neuralnetwork 

now can not import svm. line;

from sklearn import svm 

gives error;

may know went wrong? i'll try using different environments next time, if helps. there way fix this?

i using python 2.7 , sklearn 0.17.

open sklearn.utils.validation , delete "import check_arrays", or use other package example anaconda3. check - no problems. or install anaconda3.5 , copy check_arrays anaconda2.7 sklearn.utils.validation.
