The question about setting FINE_SIZE in Config

[Jebearssica]

Since the default value is -1 and there's no change in whole repo. The following data fragment shows the "RandomCrop" will never employed. May I ask about the reason for settting FINE_SIZE as the parameter?

RandomCrop(fine_size) if fine_size > 0 else None,

One usage of FINE_SIZE is stacking multiple images with different size into a batch; however, we use batch_size=1 in our experiment.
