Utilizing the Newest Diffusers Monkey Patching perform to load LoRA produces precisely the identical outcome examine with A1111

Pull the most recent code from Hugging Face’s Diffusers code repository, and located that the most recent code up to date associated to LoRA loading is up to date and may do Monkey-Patching LoRA loading now.
To put in the most recent Diffusers:
pip set up -U git+https://github.com/huggingface/diffusers.git@principal
The LoRA loading perform was producing barely defective outcomes yesterday, in keeping with my take a look at. This text discusses use the most recent LoRA loader from the Diffusers bundle.
Load LoRA and replace the Secure Diffusion mannequin weight
It has been some time since programmers utilizing Diffusers can’t have the LoRA loaded in a simple approach. To load LoRA to a checkpoint mannequin and output the identical outcome as A1111’s Secure Diffusion Webui did, we have to use extra customized code to load the weights as I supplied on this article.
The answer supplied on this article works nicely and quick, whereas it requires extra administration on the LoRA alpha weight, we have to create a variable to recollect the present LoRA weight α. As a result of the load LoRA code merely provides put the A and B matrix from LoRA collectively.
After which merge with the primary checkpoint mannequin weight W.
To take away the LoRA weights, we’ll want a adverse -α to take away the LoRA weights, or recreate the pipeline.
The Monkey-Patching technique to load LoRA
One other approach to make use of LoRA is patching the code that executes the module ahead course of, and bringing the LoRA weights through the time of calculating textual content embedding and a spotlight rating.
And that is how Diffusers LoraLoaderMixin’s strategy to LoRA loading. The nice a part of this strategy is that no mannequin weight is up to date, we will simply reset the LoRA and supply a brand new α to outline the LoRA weight.
