Cuda Support not avaliable for yolov8 on jetson nano?

Hi,

Only JetPack 4 supports Nano.
If you want to use JetPack 5, please change to Xavier or Orin series.

We only provide the PyTorch package with the default Python version.
So for JetPack 4, it’s Python 3.6.

But you can still build the PyTorch with CUDA support for custom Python from the source.
The instructions can be found in the below topic:

Thanks.
