[Problem Solved]Couldnot build OpenCV DNN

The same issue as here. Thank you very much for your help.

Now I'm trying to use cuDNN on my Jetson nano, but build is not successable. I've eddited your build_opencv.sh just these 2 lines,

111 -D CUDA_ARCH_BIN=5.3 112 -D CUDA_ARCH_PTX=5.3

and I've ran this script.

sudo ./build_opencv.sh

Then I got these Output.

Do you wish to remove temporary build files in /tmp/build_opencv ?
(Doing so may make running tests on the build later impossible)
