I am trying to use cuda-dbg under wsl2, my driver version is 531.41 and cuda version is 12.1. GPU card is RTX 2060S. when I use cuda-gdb to debug my program, It reports “Error: Internal error reported by CUDA debugger API (error=CUDBG_ERROR_INTERNAL(0xa)). The application cannot be further debugged…

Hello Hiao, could you please check if the registry key HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\GPUDebugger\EnableInterface is present, with a value of (DWORD)1? If not, create it and try again.

Yes，I have checked. The registry key “EnableInterface” is already set to 1(REG_DWORD).

Can you please provide the output of nvidia-smi?

Thank you @hiao , can you run any cuda app outside of the debugger? Also, can you try with the latest toolkit version 12.1U1?

yes, I can run cuda app outside the dubbger. And I have just tried the latest version, the question is still existing.

I am having a similar issue. was there ever a resolution or do we just have to wait for cuda 12.2?

The issue is under investigation, how did you set up your WSL environment with CUDA?

I am also having a similar issue. My GPU is RTX 3050 Laptop. I have tried different driver versions and cuda versions, but it didn’t work.
