What does this PR do?

  • Introduce a flag only_target_transformer_blocks in the train_control_flux.py script. This only trains the transformer blocks along with the x_embedder layer. Results show that it works.
  • Introduce a flag log_dataset_samples which lets users log samples to wandb (properly guarded). One can check this wandb run page to see that it works.
  • Modifies the dataloader such that when a dataset caption column has a list of different captions we only take the largest one. This lets us train on datasets like this: https://huggingface.co/datasets/TIGER-Lab/OmniEdit-Filtered-1.2M. We could randomly sample, too but for now, this is okay IMO.
  • Some additional changes to the README, fixing some argument names.
