How to disable logging temporarily?

[jatentaki]

My LightningModule.training_step includes calls to self.log and finally returns the loss value. What is the best way to run training_step outside of a Trainer context, for debugging purposes (such as manual gradient inspection, etc)? Without the instrumentation by Trainer, logger is not defined and self.log calls cause an exception. I was trying to mock the logger to turn them to no-ops, but I wasn't successful.

Good to know, thanks!
