What's your opencv version, please？

Hello, please reply after you see it.

Hi @mantou22 apology you are facing issues compiling the code. Do you have required libraries used in setup.py? Also I used opencv3.

@mantou22 I also meet the same problem, which is caused by lacking two opencv libraties, i.e., opencv_imgproc and opencv_imgcodecs in my situation. The solution is adding them in the dependent libraries. Specifically, change the line 16 of setup.py as "libraries = ['opencv_core', 'opencv_imgproc', 'opencv_imgcodecs', 'opencv_highgui','opencv_video','opencv_videoio', 'gsl', 'gslcblas'],", and then recompile the code. Note the old generated folder "build" must be first deleted before the recompiling.
