Lesson 1 - What is the difference between the two tables

Part 1 2022

Hi,
In lesson 1, while the model learns, it outputs 2 tables which have identical headers (epoch, train_loss,…). The first table has only epoch 0, and the second table goes from epoch 0 to as many epochs that are defined. What is the difference between epoch 0 in the first table and epoch 0 in the second table ?

Two tables, initial frozen epoch/s followed by the unfrozen epochs.

Fine tune with Learner.freeze for freeze_epochs , then with Learner.unfreeze for epochs , using discriminative LR.

docs: learner.fine_tune

More on Unfreezing and Transfer Learning in the fastai book CH05_pet_breeds
