Hello,
I am currently trying to setup OpenCV DNN module with CUDA support for Jetson TX2 board. I have flashed Jetpack 4.6.3 in the TX2 board with CUDA 10.2.1 and OpenCV 4.1.1, these are installed through through the NVIDIA SDK manager installation for TX2 (followed JETSONHACKS youtube video).
But when I ran object detection with CUDA, I encountered this error " [setUpNet DNN module was not built with CUDA backend; switching to CPU]". As per few blog suggestion I followed Setup OpenCV-DNN module with CUDA backend support (For Linux) - TECHZIZOU
these steps. But at the end I am not getting the OpenCV version as 4.5.5, it is still 4.1.1 which doesn’t support CUDA DNN module.
Could anyone have an idea how to solve this issue? Is OpenCV 4.5.5 the right version for the above jetpack version installed?
Also, i couldn’t find any nvidia drivers in TX2, so nvidia-smi command didnt work for me, I wanted to manually install nvidia-440 driver which supports 10.x CUDA version.
