Installing OpenCV on Windows 10 for Python 3

Question

I've downloaded and extracted OpenCV from the official website. I've learnt from this page that OpenCV 3 has Python 3 support, so my question is, why is there only the 2.7/ directory under the [opencv]/build/python/ directory??? Why isn't there a directory for Python 3?

Obviously, the cv2.pyd files in the 2.7/x64/ and 2.7/x86/ directories do not work with Python 3, but they do work with Python 2.7.

There is an option to install opencv via pip pip install opencv-python

USING opncv310 , ON vc2010 , WIN10 Home. My software was working find until January 17 , and stop working ( most of the Open CV functions crash) .

I tried other several PCs with win 7 and win 10 Pro , The same exe and dlls working find. I tried other PC with win 10 Home , didn't work too.

So, my conclusion is that in January WIN 10 Home did some UPDATE that made OPENCV to fail.
