RTX 5090 not working with PyTorch and Stable Diffusion (sm_120 unsupported)

Accelerated Computing CUDA CUDA Setup and Installation

Hello,

I recently purchased a laptop with an Hello,

I recently purchased a laptop with an RTX 5090 GPU (Blackwell architecture), but unfortunately, it’s not usable with PyTorch-based frameworks like Stable Diffusion or ComfyUI. The current PyTorch builds do not support CUDA capability sm_120 yet, which results in errors or CPU-only fallback.

This is extremely disappointing for those of us who invested in high-end hardware expecting out-of-the-box support for AI tools.

Could NVIDIA please work closely with the PyTorch team to ensure official support as soon as possible?

Thanks for your attention.
