Windows10 WSL2 get error “cudaErrorInsufficientDriver”

System info:
Window10 1909(OS internal version 18363.1139)
NVIDIA GeForce RTX 2080

First, I install cuda driver with 460.20_gameready_win10-dch_64bit_international and get info as blow:

PS C:\Users\Neo> nvidia-smi.exe
| NVIDIA-SMI 460.20 Driver Version: 460.20 CUDA Version: 11.2 |
| GPU Name TCC/WDDM | Bus-Id Disp.A | Volatile Uncorr. ECC |

| N/A 35C P8 5W / N/A | 919MiB / 8192MiB | 15% Default |
| | | N/A |

Then I Install Linux subsystem

PS C:\Users\Neo> wsl --list --verbose

  • Ubuntu-18.04 Running 2

PS C:\Users\Neo> wsl cat /proc/version
Linux version 4.19.128-microsoft-standard (oe-user@oe-host) (gcc version 8.2.0 (GCC)) #1 SMP Tue Jun 23 12:58:10 UTC 2020

Third, I Install cuda on linux subsystem, but get error when I run the BlackScholes

sudo sh

For CUDA in WSL2 you need a Windows Insider build version 20145 or superior.

CUDA on WSL :: CUDA Toolkit Documentation (

my win10 is 20246,but have the same problem

In that case you need to uninstall the CUDA driver inside WSL2. This can be tricky so I recommend to uninstall your distro and install again.
In a brand new distro install you only need the Windows driver installed. You will know the GPU is detected if the file /dev/dxg exists.
