LyCORIS

LyCORIS (Lora beYond Conventional methods, Other Rank adaptation Implementations for Stable diffusion) are LoRA-like matrix decomposition adapters that modify the cross-attention layer of the UNet. The LoHa and LoKr methods inherit from the `Lycoris` classes here.

A base layer for LyCORIS like adapters

####
merge

< source >

( safe_merge: bool = False adapter_names: Optional[list[str]] = None )

Parameters

- safe_merge (`bool`, optional) — If `True`, the merge operation will be performed in a copy of the original weights and check for NaNs before merging the weights. This is useful if you want to check if the merge operation will produce NaNs. Defaults to `False`.
- adapter_names (`List[str]`, optional) — The list of adapter names that should be merged. If `None`, all active adapters will be merged. Defaults to `None`.

Merge the active adapter weights into the base weights

####
unmerge

< source >

( )

This method unmerges all merged adapter layers from the base weights.

( model peft_config: Union[PeftConfig, dict[str, PeftConfig]] adapter_name: str low_cpu_mem_usage: bool = False state_dict: Optional[dict[str, torch.Tensor]] = None )

Parameters

- model (`torch.nn.Module`) — The model to be adapted.
- config (LoraConfig) — The configuration of the Lora model.
- adapter_name (`str`) — The name of the adapter, defaults to `"default"`.
- low_cpu_mem_usage (`bool`, `optional`, defaults to `False`) — Create empty adapter weights on meta device. Useful to speed up the loading process.
