I have build OpenCV with WITH_CUDA=ON based on
With some changes as below successfully:
- commented out the line
sudo apt-get dist-upgrade -y --autoremove
as it upgraded JetPack 4.4.0 to 4.4.1 which resulted the e-con system camera does not work.
as I am using Qt Creator for coding and debugging.
But the line below return 0 during my test
int count = cuda::getCudaEnabledDeviceCount();
No CUDA enabled device is available, why?
How to fix it?
