Deep Learning using GPU

Hi,

I tried to train data with Deep Learning using the GPU (Nvidia GTX 960M) but I obtained the following error message: "an unexpected error occurred during cuda execution. the cuda error was: CUDA_ERROR_UNKNOW" Despite the fact that I have installed the last Nvidia drivers and when I run "gpuDevice" the computer recognize the GPU.

Please your advice. Thanks, Itai

The most likely explanation is a kernel timeout, see https://uk.mathworks.com/matlabcentral/answers/410236-cuda-error-after-calculating-mahalanobis-distance-for-large-dataset.

The next most likely is lack of memory not being handled properly on your low power laptop GPU. Try reducing your MiniBatchSize.

Generally, search for CUDA_ERROR or 960M and you'll find a variety of issues that can arise with these laptop chips.
