Hi,
The latest software for Nano is JetPack 4.6.3.
You can try the installation command below:
$ export TORCH_INSTALL=https://developer.download.nvidia.com/compute/redist/jp/v461/pytorch/torch-1.11.0a0+17540c5+nv22.01-cp36-cp36m-linux_aarch64.whl
$ python3 -m pip install --no-cache $TORCH_INSTALL
Thanks.
