Hello I am getting error while running nueral network programs the error is "Error using parallel.gpu.CUDADevice.hBuild An unexpected error occurred trying to retrieve CUDA device properties. The CUDA error was: CUDA_ERROR_UNKNOWN" few days back it used to run properly from 2 days it is displaying this error. even i tried updating drivers no use. please help me .

Please give MATLAB version, device, system information, and output of nvidia-smi.

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).

select high performance option for MATLAB on NVIDIA control panel to solve. It works :)

These mobile graphics chips are very flaky for CUDA execution because of their power requirements. Try rebooting; also, go to the NVIDIA Control Panel, Manage 3D Settings, then ensure that in Program Settings, when MATLAB is selected, the High-performance NVIDIA processor is the preferred graphics processor.

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.
