How to put your module in OpenCV?

Question

Python

Hello everyone, I need to wrap OpenCV to use GPU modules as there is no support for Python.
I found a repo in which there is a solution, but for some reason the pythoncuda module, which is opencv_contrib/modules, does not work inside python after compilation, that is, cv2.pythoncuda gives an import error, tell me what I'm doing wrong, or what's wrong with the repo.
Repo: https://github.com/NeerajGulia/python-opencv-cuda
My cmake

cmake \
