SVM import failed after installing scikit-neuralnetwork

Question

I just installed Python's scikit-neuralnetwork using the procedure mentioned, that is;

pip install scikit-neuralnetwork

Now I can not import SVM. This line;

from sklearn import svm

gives this error;

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "//anaconda/lib/python2.7/site-packages/sklearn/svm/__init__.py", line 13, in <module>

    from sklearn.utils.validation import check_arrays
ImportError: cannot import name check_arrays

May I know what went wrong? I'll try using different environments next time, if that helps. Is there any way to fix this?

I am using Python 2.7 and sklearn 0.17.

Answer 1

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