question: Access trainer parameters from LightningModule
context: Hi,
  I was wondering how could i access trainer parameters from a LightningModule.
  I want indeed to do setup that depend on max_epochs. Configure a linear decay lr scheduler and also i want to take some special action on the validation step on the last epoch.
  Thanks for the help!
answer: @nicolas-dufour You can access it with self.trainer.max_epochs.
