question: Can I set the epoch/step initial value to 1?
context: Can I set the epoch/step initial value to 1? Now the initial default is 0, it feels awkward when watching Tensorboard.
  In addition, can I bring plots in the training and valid in one tersorboard plot?
answer: Dear @yuys0602,
  We are starting at 0 as we are counting the number of epoch and before starting, you actually haven't completed any epoch.
  If this is really an issue for you, I believe there might be a hacky solution.
  I believe this should be working if you are using master. @carmocca Could you confirm ?
  def training_step()
  
      self.log("epoch", self.trainer.current_epoch + 1)
  
  Concerning, can I bring plots in the training and valid in one tersorboard plot?
  Unfortunately, I believe this is a feature provided or not by Logger and Lightning can't do much about it.
  Best,
  T.C
