Error while teaching neural network Alexnet

Hello. I use Alexnet neural network for lane detection. While reteaching it with new frames of road, i have an error:
An unexpected error occurred during CUDA execution. The CUDA error was: CUDA_ERROR_LAUNCH_FAILED
I have GeForce 840M GPU. Matlab uses it for teaching.
But when i use CPU for teaching(different PC (without discrete GPU) is used), it works properly, but it takes very long time.
If have any ideas how to solve it, please tell them.

It is possible you are encountering a kernel execution timeout which is imposed by the operating system on processes running on the GPU for longer than a few seconds. We have more information about it here: https://www.mathworks.com/matlabcentral/answers/99300
After you've encountered that error can you do any other code that interacts with the GPU successfully without restarting MATLAB? e.g.
A=gpuArray.rand(1)
If you can't then I would strongly suspect the execution timeout to be to be the problem.
