there is indeed some bug in the python wrappers, that allows you to write code like this:

cd = cv2.cuda_CannyEdgeDetector() # invalid object !

where you would have to use a factory function:

cd = cv2.cuda.createCannyEdgeDetector(...)

same applies for:

.hd = cv2,cuda.createHoughLinesDetector(...)

It is not a CUDA-related problem in my opinion
