On a Windows 10 box, with Cuda 8.0.61 installed, cudaGetDeviceCount() returns 0 with the error code 38 (cudaErrorNoDevice).
Below, the raw output obtained by running “nvidia-smi.exe -a”.
I am bit baffled by the error, because the two GPUs are working fine, but they just aren’t seen by Cuda.
Does anyone know how I could fix the problem?
Thanks!
Joannes
