deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 10.1, CUDA Runtime Version = 9.0, NumDevs = 1
Result = PASS

I have noticed that there is no device in the last line, like in the example from your website:

Please help me.

I remain available for any further details (I will try because I am not an IT person…)



I still cannot use my GPU with neural networks.
