Error
Training throws the error 'CUDA_ERROR_UNKNOWN'
Description
Sometimes, the GPU throws this error when it is being used for both compute and display requests from the OS.
Possible Solution
Try reducing the mini-batch size using the 'MiniBatchSize' option of trainingOptions. If reducing the mini-batch size does not work, then in Windows®, try adjusting the Timeout Detection and Recovery (TDR) settings. For example, change the TdrDelay from 2 seconds (default) to 4 seconds (requires registry edit).

I am getting the following error when I try to train my network : Error using parallel.gpu.CUDADevice.hBuild
An unexpected error occurred trying to retrieve CUDA device properties. The CUDA error was:
CUDA_ERROR_UNKNOWN
I an using Nvidia Geforce GTX 1050 TI GPU on my Windows 10 Laptop. When I restart Matlab, error goes away but reappears when I train network again. I have the latest Nvidia driver. I feel that I hve started getting this error after I installed Cuda toolkit 9 and CuDNN libraries to make tensorflow for GPU work?
Interestingly my GPU is dectable using the various MATLAB commands.

I have the same error, what works for me is using the command: gpuDevice(1)
I was hoping to find a better alternative to my solution, but maybe there's none other.
