>>> torch.cuda.is_available() False in Jetson Xavier AGX

[a.elhanashi]

Hi

I have an issue for using torch and pytorch with python 3.8 in Xavier AGX. torch.cuda.is_available() False. i need to use python 3.8 to run yolov8 xavier agx.

I tried to follow this link to install torch and pytorch that to be compatible but it does not work for me

PyTorch for Jetson

Below are pre-built PyTorch pip wheel installers for Jetson Nano, TX1/TX2, Xavier, and Orin with JetPack 4.2 and newer. Download one of the PyTorch binaries from below for your version of JetPack, and see the installation instructions to run on your Jetson. These pip wheels are built for ARM aarch64 architecture, so run these commands on your Jetson (not on a host PC). You can also use the containers from jetson-containers. PyTorch pip wheels JetPack 6

PyTorch v2.2.0

JetPack 6.0 DP (L4T R3…

because examples and files are for 3.6

kindly, if i can get step by step code for installing pytorch and torch that are compatible for python 3.8 on jetson xavier AGX to get cuda avaliable true

i attached the xavier agx info for your reference

Hi @a.elhanashi, I would recommend reflashing your Xavier with JetPack 5 so that you can use Python 3.8 and our precompiled PyTorch wheels for it. You may be able to build PyTorch from source for Python 3.8 against CUDA 10.2 and JetPack 4.6, but I’m not sure if PyTorch still supports it or not.

Ok How to install from source in the link above i found only for python 3.6 but not for python 3.8?

[dusty_nv]

You would need to install python3.8-dev and pip3.8, and use python3.8/pip3.8 instead when invoking the build/install commands. I’ve not tried this on JetPack 4 with recent versions of PyTorch.

Will i use the same wheel files of python 3.6 for python 3.8. Cuz all files in the above link is for python 3.6

[dusty_nv]

No, you need to rebuild PyTorch from source to make the wheels for Python 3.8 on JetPack 4. You can’t install wheels built for Python 3.6 in a Python 3.8 environment. If you are unsure about this, I would recommend updating your system to JetPack 5 unless you have some other reason not to.
