The GPU isn't working when initializing Genesis on the Jetson AGX Thor...

[robothwang]

The original computer specifications are as follows:
CPU: Intel Core i7-14700F
RAM: 64GB
GPU: NVIDIA GeForce GTX1080 (8GB)

I was lucky enough to get Thor and am currently using it, but the following error occurs when applying gs.init(backend=gs.gpu). Is there any way to resolve this?

The key line is sm_110 is not a recognized processor. That means the CUDA toolchain on the machine is too old for Thor, so Genesis cannot compile the GPU kernels for that architecture. This is not something you fix inside Python. Update to a JetPack and CUDA stack that knows sm_110, then reinstall the GPU packages in a clean environment. Until then, gs.gpu will keep failing and gs.cpu is the only reliable fallback.

This issue has been fixed on genesis main.
