LyCORIS 2.0.0

We are excited to announce that LyCORIS project has just been updated to version 2.0.0. This update brings a plethora of new features and improvements!

🎉HCP-Diffusion supports🎉

LyCORIS is now starting to support training/inference in HCP-Diffusion

• Now LyCORIS support LoHa/LoKr/Diag-OFT algorithm in HCP-Diffusion
• Add Pivotal tuning utilities
• Add hcp convert utilities
• Have no plan at this time to support full/lora and train_norms since HCP can do them natively

🌟New Implemented Algorithms🌟

• Diag-OFT
  • Ref: Controlling Text-to-Image Diffusion by Orthogonal Finetuning
  • A1111 sd-webui supports
  • Also support HCP!

🚀New features🚀

• Standalone usage (For any pytorch module):
  • Can wrap any pytorch module which contains Linear/Conv2d/LayerNorm/GroupNorm modules
  • A project which utilize LyCORIS to finetune Phi-1.5: HakuPhi
  • minimal example:

from lycoris import create_lycoris, LycorisNetwork

LycorisNetwork.apply_preset(
    {"target_name": [".*attn.*"]}
)
lycoris_net = create_lycoris(
    your_model, 
    1.0, 
    linear_dim=16, 
    linear_alpha=2.0, 
    algo="lokr"
)
lycoris_net.apply_to()

# after apply_to(), your_model() will run with LyCORIS net
lycoris_param = lycoris_net.parameters()
forward_with_lyco = your_model(x)

• Merge scripts now support SDXL
• Extract locon script now support SDXL

Fixed Bugs

• Dropout have inversed rate. (dropout=a will performed as dropout=(1-a))
• appy_max_norms will have divided by zero error
• cannot resume correctly
