CUDA fails to launch while running seq2seq model

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.
