Enabling logger during fast_dev_run?


I would like to test out multiple metrics and visualization for the loggers and to have quick iterations I use fast dev run, however that mode does not enable logging.

Is it possible to enable it while fast dev run is active?

fast dev run will always disable loggers, but you can limit your train val samples and max epoch to do a quick iteration.

You need to set the following flags in the Trainer -
limit_train_batches, limit_val_batches, max_epochs=1
