Hello,
I installed opencv-python using the answer given by @user3731622 in the following post: https://stackoverflow.com/questions/20953273/install-opencv-for-python-3-3
I can import cv2 but when I try import cv2.cv as cv I get the error mentioned in the title.
I have the version opencv-python-3.1.0 and I use Python 3.5.1 on Windows.
