WSL2 CUDA driver detected on Windows but not on Ubuntu subsystem

Question

Hi, all!

I have enabled all Hyper-V features, Virtualization, and Linux subsystem on Windows feature. And installed Ubuntu 20.04 from Windows Store.

In Windows Shell, when Input:

C:\Users*****>nvidia-smi

The output is:

Sun Feb 20 22:29:03 2022

But in the Ubuntu 20.04 subsystem, when input:

*****@DESKTOP-L5VP5OD:~$ nvidia-smi

The output is:

Failed to initialize NVML: GPU access blocked by the operating system

Failed to properly shut down NVML: GPU access blocked by the operating system

When input:

*****@DESKTOP-L5VP5OD:~$ sudo nvidia-smi

It responds:

sudo: nvidia-smi: command not found

But all the drivers are there in this subsystem, when type:

*****@DESKTOP-L5VP5OD:~$ ls /usr/lib/wsl/lib

It gives the output:

libcuda.so libd3d12.so libnvcuvid.so libnvidia-encode.so libnvidia-opticalflow.so nvidia-smi

libcuda.so.1 libd3d12core.so libnvcuvid.so.1 libnvidia-encode.so.1 libnvidia-opticalflow.so.1

libcuda.so.1.1 libdxcore.so libnvdxdlkernels.so libnvidia-ml.so.1 libnvwgf2umx.so

What could be the cause?
Thanks in advance! Any help would be appreciated!
