【问题描述】：

我正在使用 TensorFlow 训练深度学习模型，并且该模型已成功训练，但最后它会向我返回此错误消息：

Exception ignored in: <function Pool.__del__ at 0x7fbf30520550>
Traceback (most recent call last):
  File "/usr/lib/python3.8/multiprocessing/pool.py", line 268, in __del__
    self._change_notifier.put(None)
  File "/usr/lib/python3.8/multiprocessing/queues.py", line 368, in put
    self._writer.send_bytes(obj)
  File "/usr/lib/python3.8/multiprocessing/connection.py", line 200, in send_bytes
    self._send_bytes(m[offset:offset + size])
  File "/usr/lib/python3.8/multiprocessing/connection.py", line 411, in _send_bytes
    self._send(header + buf)
  File "/usr/lib/python3.8/multiprocessing/connection.py", line 368, in _send
    n = write(self._handle, buf)
OSError: [Errno 9] Bad file descriptor

对我来说，这看起来像是一个池析构函数错误，但我不确定如何修复它，知道为什么会发生吗？
