Re: SANA full-rank finetuning/training

[gitanon112]

Hello,

Thank you for your guide on full-rank training SANA. I just had a couple of questions:

1. Is the training guide still up-to-date/will it work for full-rank training of 2K Sana model?
2. What is the rationale to use SimpleTuner vs SANA native scripts(https://github.com/NVlabs/Sana/blob/main/train_scripts/train.py and https://github.com/NVlabs/Sana/blob/main/train_scripts/train.sh are full-rank training scripts for SANA I believe?). Is SimpleTuner faster?
3. So is the advantage of full-rank training that we can train on large image dataset(like 10k+ images) and we wouldn't be able to do dreambooth training with this many images?
4. If my goal is to make SANA 2k model(which currently struggles with human image generation) capable/better at generating human images, is it as simple as full-rank training on dataset with high-quality human image-text pairs? Or is it more complex than this?

Thanks so much for the help and your work, really appreciate it!
