Lesson 2: Help wanted with plotting & data augmentation


I’m working through the code for Lesson 2 and wondering if anyone can help me with the following:

  • Is there a function that allows me to determine the number of examples in the validation/training dataset after doing data augmentation using aug_transforms and then passing the datablock template into dataloaders? I would like to keep track of how many examples there are.

  • How could I go about plotting the training/validation losses while I am training the resnet learner?

  • Is there a parameter I can add to search_images_ddg that makes it retrieve more images?
