Jetpack 4.4 Opencv installation

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.


Default opencv from SDKM does not have GPU enabled. So you have to build it from scratch again.

You need to build it from scratch.
