OpenCV with GPU Acceleration on Jetson Xavier NX Jetpact 4.4

After installing the latest Jetpack (4.4) yesterday on Xavier NX, OpenCV face_recognition has become unstable and extremely slow. I suspect GPU acceleration no longer works. If true, how can I install OpenCV with GPU Acceleration? Any insight/comment on this issue is greatly appreciated.


Please try to re-install OpenCV with the script and try again:

It enables -D WITH_CUDA=ON. May be required for face recognition with GPU acceleration.
