@akulchik - what toolkit version are you using and what OS? The change looks good but interested to understand what version of the Cuda toolkit does not have the device query executable file. It's in 12.4 which is the current toolkit.

@rosslwheeler I use Ubuntu 22.04 on WSL 2. Funny, because I have indeed CUDA (and the toolkit) 12.4 installed.

$ nvidia-smi --version
NVIDIA-SMI version  : 550.76.01
NVML version        : 550.76
DRIVER version      : 552.22
CUDA Version        : 12.4

Just did a check on an older 11.7 Cuda SDK and the file is there. I think your installation might have a problem. I do like your change but not sure it it's urgent unless it's critical that we support the older SDKs with auto-detect. Can you try either reinstalling or using the latest 12.4.1 SDK? The file is supposed to be installed with nvcc.

Ok, I will try to install the latest SDK version and let you know the results, thanks.
