@nguyen.thai.son1 those wheels from pytorch.org aren’t built for JetPack and won’t work with CUDA on Jetson. Instead, please install the PyTorch wheel from the link that @AastaLLL linked to or from here: https://forums.developer.nvidia.com/t/pytorch-for-jetson
If you are still having issues with PyTorch to have CUDA/cuDNN working, you can also try the l4t-pytorch or l4t-ml containers which already have that pre-installed. Those containers also have OpenCV+CUDA already installed in them.
