Visual studio 2013 can't import cv2

asked 2016-04-21 08:18:39 -0500

I tried to follow this link to compile opencv on visual studio 2013 :

http://docs.opencv.org/3.1.0/d5/de5/t...

However, I got this error when I run import cv2 command on python IDLE:

ImportError: DLL load failed: The specified module could not be found.

Can anyone tell me how to solve this problem?

  • did you build the INSTALL project ? (this should make the python bindings & copy them to your site-packages folder)

  • is there a cv2.pyd in your python/lib/site-packages ?

  • try from a plain cmdline, not IDLE.

yes, I build the INSTALL, and cv2.pyd also exists in my python/lib/site-packages folder. my python version is 2.7.10

I had the same issue, but found a solution that worked for me.

After building INSTALL in Visual Studio 2013, I had to add this to my System path variable.
(location to your opencv directory)\build\bin\Release

After that, I was able to open the python command line or python IDLE and "import cv2" worked. I hope that this helps.
