When I train the sequence to sequence model. This error occurred--
Warning: An unexpected error occurred during CUDA execution. The CUDA error was: CUDA_ERROR_LAUNCH_FAILED
After that, I can't use the GPU to run any function like gpuArray(). There is no problem when I train any image classification model after restarting the Matlab or before running this model.
model: #sample 1250 in each segment
