Error in loading Civit AI Lora: LCMTurboMix_Euler_A_fix

[ali-afridi26]

Describe the bug

This CIVITAI Lora has over 20k downloads and doesn't work with SDXL Pipeline. It is giving lora_unet_down_blocks_0_downsamplers_0_conv.alpha not supported error. I have uploaded the model on hugging face. Error appears on load_lora_weights() function

Reproduction

from diffusers import DiffusionPipeline

pipe = DiffusionPipeline.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0")
pipe.load_lora_weights("RhaegarKhan/LCMTurboMix_Euler_A_fix")

prompt = "<lora:LCMTurboMix2fix:1>,abstract portrait of 1girl,undefined gender,fragmented visual style,red and black color palette,evokes feelings of rebellion,passion,and freedom,blurred boundaries,high resolution,aesthetic,"
image = pipe(prompt).images[0]
