Cuda 9.0 on Ubuntu 16.04: cudaGetDeviceCount returned 35

I’m new in linux and I intend to use CUDA. I followed the instructions on https://docs.nvidia.com/cuda/archive/9.0/. After installing my nvidia gpu which is GEFORCE 820M, nvidia-340 to be specific. I installed CUDA 9.0.xx next and extracted and compiled with the sample. I tried to run ./deviceQuery and resulted in:

./deviceQuery Starting…

CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL

Checking:

I would appreciate all of help that I can help since I’m have trouble with it in 3 weeks and have reinstalled my Ubuntu 10x now.

Thanks a lot.

geforce 820m is an old GPU

CUDA 8 was the last version that supports that GPU. And if you want to use CUDA 8, you will need a newer driver than 340.xx. The driver that comes with the CUDA 8 toolkit installer should be fine.
