I'm using ubuntu 15.10 and opencv-3.1.0. When I tried to run a python code I'm getting the following error
ImportError: cannot import name cv
The same code was running fine with another ubuntu machine and opencv
Don't know whats the problem Someone kindly help
the cv module is the old c-based python wrapper. opencv moved away from that years ago, and it was removed in opencv3
please use cv2, and port your code.
Thanks for your reply.
I tried that and now I'm getting the following errors:
