Cannot detect GPU

[tnnandi]

I have installed warp within a conda environment on WSL2 on Windows (on a machine with GeForce RTX 3050 GPU), but warp doesn't seem to be able to locate the GPU.

Here are some relevant information and output:

Thanks for reporting this! CUDA support on WSL can be a bit tricky to set up. Did you follow the steps at CUDA on WSL? Pay specific attention to:

users must not install any NVIDIA GPU Linux driver within WSL 2. One has to be very careful here as the default CUDA Toolkit comes packaged with a driver, and it is easy to overwrite the WSL 2 NVIDIA driver with the default installation. We recommend developers to use a separate CUDA Toolkit for WSL 2 (Ubuntu) available from the CUDA Toolkit Downloads page to avoid this overwriting.

The above page also contains other troubleshooting advice. Please let us know if you're able to run other CUDA workloads within WSL, but not Warp.
