I am using a Jetson Orin Nano of course. I have tried building OpenCV a couple of times including onces with -D WITH_CUDA=ON and other times from posts like these but when I python -c "import cv2; print('CUDA support:', 'Yes' if cv2.cuda.getCudaEnabledDeviceCount() > 0 else 'No')" I see that CUDA is not supported. Please help.

What is the build information in Python from your OpenCV installation? Did you set the PYTHONPATH to point to the new build?

Hi,
Please try the script to manually build OpenCV:

I ended up using this successfully.
