Hey people, currently I am trying to implement basic OpenCV function on Nvidia Jetson TX2 development board. I flash Jetpack 4.4 to my development board from Ubuntu 18.04 machine. After the flashing process finished, I check OpenCV version on my TX2 development board which is 4.1.1. And I can run basic OpenCV application however I am not sure whether it is installed for GPU or not. And I have no idea about should I build OpenCV from scratch or not. Need help.
