I have same isuue!
The only difference for my case is Linux version 5.10.16.3-microsoft-standard-WSL2(The version was 5.4.* but I execute ‘wsl --update’ then I got v5.10.16.3)
$ sudo nvidia-container-cli -k -d /dev/tty info
has same output.
I tried to reinstall Ubuntu18.04 on wsl2 and cuda, three times but same error occurred.
How to solve this problem?
Also, Docker Desktop backend instead of nvidia-docker2 installation mentioned in the Document [CUDA on WSL :: CUDA Toolkit Documentation (nvidia.com)], has same problem.
So, I think nvidia driver has a problem.
I want to try to use old version of nvidia driver 465.21 because someone said it works everything fine on the similar situation (470.14 - WSL with W10 Build 21343 - NVIDIA-SMI error - #20 by AKAMolasses)
Is there any way to get old version of nvidia driver for wsl?
I couldn’t find it on the nvidia website.(normal old ver. nvidia driver has found but it is not support for wsl, in my understanding)
