question: Custom scheduler
context: I would like to provide my own learning rate scheduler. What I would love is do is doing this in the lightning style, e.g. implementing some hooks:
  class MyScheduler(pl.LightningScheduler):
      ...
      def on_step(self...):
          ...
      def on_epoch(self...):
          ...
  Is something like this possible? How do other people handle custom schedulers?
  PS: I asked this question before on the [deprecated forum.]

answer: can you please elaborate on the usage more? like what do you want to do inside on_step and on_epoch methods?
