Hey,

I modified the current working code by adding cvtcolor() to convert image to grayscale and got stuck with the following error.

py_build/pbcvt.so: undefined symbol: _ZN2cv8cvtColorERKNS_11_InputArrayERKNS_12_OutputArrayEii

I couldn't run any of the API's in imgproc module(canny(),threshold()).

Solved.
Added

set OpenCV directories using find_package.

find_package(OpenCV 3.3.1 REQUIRED)

in CMakeLists.txt
