I understand that you are getting the following error: error using parallel.gpu.CUDADevice.hBuild, with a CUDA runtime error of CUDA_ERROR_UNKNOWN. Try setting the "high performance NVIDIA Processor" option for MATLAB on NVIDIA control panel. You can find it at 3D Settings -> Manage 3D Settings -> Select a program to customize. This should alleviate the CUDA errors.
For more information regarding CUDA errors while training a network on GPU, you can refer to the below MATLAB Answers thread-
