I found the issue is not about `cudaGetDeviceCount`, `cudaGetDeviceCount` doesn't return error, however, the issue is it doesn't check `CUDA_VISIBLE_DEVICES` setting but like other APIs do. When you set `CUDA_VISIBLE_DEVICES` to empty, checking `kExist` will return true, and other attrs will checked and cause no device error. I think we should recover the original check before #16377 that uses `cudaDeviceGetAttribute` and clear the error code if not exists -- This is an automated message from the Apache Git Service.
