Hi,

I’m facing an issue on an Nvidia Jetson Orin Nano where the GPU is not being detected.
nvcc --version command shows that CUDA 12.2 version is installed.

Nvidia jetpack 6.0 is isntalled
Package: nvidia-jetpack
Version: 6.0-b52
Architecture: arm64
Maintainer: NVIDIA Corporation
Installed-Size: 194
Depends: nvidia-jetpack-runtime (= 6.0-b52), nvidia-jetpack-dev (= 6.0-b52)
Homepage: Jetson - Embedded AI Computing Platform | NVIDIA Developer

I have installed pytorch packages on this link which is compatible with Cuda 12.2
https://developer.download.nvidia.com/compute/redist/jp/v60/pytorch/torch-2.4.0a0+07cecf4168.nv24.05.14710581-cp310-cp310-linux_aarch64.whl

Sudo jtop shows the gpu

Other libraries version are here
OpenCv version 4.9.0[installed]

Pytorch Version 2.3.1[installed]
libcudnn8/stable,now 8.9.4.25-1+cuda12.2 arm64 [installed]
libcudnn8-dev/stable,now 8.9.4.25-1+cuda12.2 arm64 [installed]
libcudnn8-samples/stable,now 8.9.4.25-1+cuda12.2 arm64 [installed]

But PyTorch says that cuda is not available:

Hello,

Welcome to the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

I will move this post over for visibility.

Cheers,
Tom

Hi,

It doesn’t mean GPU is not available.
Usually, PyTorch means the package isn’t built with CUDA support.

To solve this, please re-install PyTorch with our package that has been built with CUDA:

Thanks.
