hi, i have a problem about train.py: 2019-04-09 16:59:35.321468 Progress: [##########] 100% Done...99999%
mean loss: 8.890891 Process ForkPoolWorker-1:35: Traceback (most recent call last): File "/home/student/anaconda3/envs/tensorflow1.4/lib/python3.5/multiprocessing/pool.py", line 125, in worker put((job, i, result)) File "/home/student/anaconda3/envs/tensorflow1.4/lib/python3.5/multiprocessing/queues.py", line 347, in put self._writer.send_bytes(obj) File "/home/student/anaconda3/envs/tensorflow1.4/lib/python3.5/multiprocessing/connection.py", line 200, in send_bytes self._send_bytes(m[offset:offset + size]) File "/home/student/anaconda3/envs/tensorflow1.4/lib/python3.5/multiprocessing/connection.py", line 397, in _send_bytes self._send(header) File "/home/student/anaconda3/envs/tensorflow1.4/lib/python3.5/multiprocessing/connection.py", line 368, in _send n = write(self._handle, buf) BrokenPipeError: [Errno 32] Broken pipe

During handling of the above exception, another exception occurred:
