I am observing a similar problem.
I hava a Windows 7 laptop with a NVidia Quadra M2000M card. The CUDA GPUs website lists a compute capablity of 5.0. I installed the latest Nvidia graphic drivers (388.16), CUDA v8.0 and cudnn v6 for Cuda 8.
deviceQuery shows the following error:
C:\ProgramData\NVIDIA Corporation\CUDA Samples\v8.0\bin\win64\Release\deviceQuery.exe Starting…
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 38
→ no CUDA-capable device is detected
Result = FAIL
When I run deviceQuery, a Windows alert pops up: 'Das Gerät “NVIDIA Quadro M2000M” ist kein Wechselgerät und kann daher nicht abgedockt oder entfernt werden." (The device NVIDIA Quadro M2000M is not a pluggable device and therefore it cannot be unplugged or removed.)
nvidia-smi.exe gives me the following output:
“c:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe”
