How do I install the OpenCV module opencv_contrib in WinPython?

The build procedure for OpenCV looks way too complicated to be successful on my computer. I could not even install Python successfully (I tried for two weeks and had hundreds of errors), so I had to install WinPython. I do not want to repeat and have a failed installation with opencv_contrib.

WinPython requires a exe or whl file to install. How to get a exe or whl file of opencv_contrib or OpenCV3+opencv_contrib ?

I installed OpenCV3 by using a OpenCV3cp34Win32.whl file. But not with opencv_contrib. Now I need to install opencv_contrib to use SIFT and SURF.

Windows 7 WinPython 3.4

Thanks for any help or suggestions.

I was in the same situation. It is necessary to execute the commands in the WinPython Powershell Prompt, otherwise none of those methods that you said would work (I have tried also for a long period of time). It seems to be the reason that the Winpython is portable by itself, and doesn't recognize what libraries you have outside (My theory, taking in consideration that it has and execute its own python version inside). So try these commands there pip install opencv-python (for basic open cv) or pip install opencv-contrib-python (for open cv + libraries of contributors.

Good luck
