ZeroDivisionError when extracting duration

[Charlottecuc]

Hi, when I ran duration_extractor.py, I encountered the following problem:

Traceback (most recent call last):
  File "code/duration_extractor.py", line 534, in <module>
    logdir=logdir
  File "code/duration_extractor.py", line 390, in fit
    valid_losses = self._validate(valid_loader)
  File "code/duration_extractor.py", line 466, in _validate
    self.logger.add_scalar('valid/l1', t_l1 / i, self.epoch)
ZeroDivisionError: float division by zero

Could you help me to solve this problem? Thank you very much.

Solved. The size of the val data shouldn't be less than the batch size.
