ZeroDivisionError in TensorboardWriter.set_step()

[Andry-Bal]

There is a risk of getting ZeroDivisionError: float division by zero in TensorboardWriter.set_step() method in line:
self.add_scalar('steps_per_sec', 1 / duration.total_seconds())
I get this when running example config with "tensorboard": false

I get the same Zerodivisionerror, even with "tensorboard": true
Following is the error:

  File "G:\NewTemplate\pytorch-template-master\train.py", line 73, in <module>
    main(config)

  File "G:\NewTemplate\pytorch-template-master\train.py", line 54, in main
    trainer.train()

  File "G:\NewTemplate\pytorch-template-master\base\base_trainer.py", line 61, in train
    result = self._train_epoch(epoch)

  File "G:\NewTemplate\pytorch-template-master\trainer\trainer.py", line 68, in _train_epoch
    val_log = self._valid_epoch(epoch)

  File "G:\NewTemplate\pytorch-template-master\trainer\trainer.py", line 91, in _valid_epoch
    self.writer.set_step((epoch - 1) * len(self.valid_data_loader) + batch_idx, 'valid')
