I’ve tried to install CUDA in WSL2 by following the instructions at https://docs.nvidia.com/cuda/wsl-user-guide/index.html but I can’t get it to work. I’m using Ubuntu 20.04

I installed cuda-toolkit-11-2, so there should be no driver installed in WSL to mess things up.
I can confirm that /dev/dxg exists.
The output of ls /usr/lib/wsl/lib/ is
libcuda.so libcuda.so.1.1 libd3d12core.so libdxcore.so libnvwgf2umx.so
libcuda.so.1 libd3d12.so libdirectml.so libnvidia-ml.so.1
I compiled the deviceQuery sample. Its output is as follows:
./deviceQuery Starting...
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 1
-> invalid argument
Result = FAIL
Using strace ./deviceQuery, I have confirmed it is loading /usr/lib/wsl/lib/libcuda.so.1. I’ve uploaded the full strace to https://pastebin.com/jcxVQyRh. I also tried a couple of other samples but they didn’t work either.
Looking at this, can anyone tell where I’ve gone wrong? I’ve tried the process twice, including deleting my WSL install and doing a clean-install of the driver.
