RuntimeError: DataLoader worker (pid(s) 18360) exited unexpectedly

While running train_Stack.py I am getting below error:

Traceback (most recent call last):
File "D:\Innovation day 2019\python\lib\site-packages\torch\utils\data\dataloader.py", line 724, in _try_get_data
data = self._data_queue.get(timeout=timeout)
File "D:\Innovation day 2019\python\lib\multiprocessing\queues.py", line 105, in get
raise Empty
_queue.Empty

During handling of the above exception, another exception occurred:
