Diffusers 包已将unet_2d_blocks.py 移至“diffusers/models/unets/”路径，而不是以前的“diffusers/models/”路径。 LCM_Inpaint_Outpaint_Comfy/LCM的py文件（包括LCM_lora_inpaint.py,LCM_refinpaint_pipeline.py,LCM_reference_pipeline.py,LCM_lora_inpaint_ipadapter.py,pipeline_cn_reference_img2img.py,pipeline_inpaint_cn_reference.py,stable_diffusion_reference_img2img.py,stable_diffusion_reference_img2img_controlnet.py）应从 更改from diffusers.models.unet_2d_blocks import UNetMidBlock2D, get_down_block, get_up_block为from diffusers.models.unets.unet_2d_blocks import UNetMidBlock2D, get_down_block, get_up_block。

I changed in workflow.json \ to /

You have to replace from diffusers.models.unet_2d_blocks to from diffusers.models.unets.unet_2d_blocks (everywhere) its in like a 20 places.

LCM_Inpaint_Outpaint_Comfy\LCM When diffusers.models.unet_2d_blocks of py files in this folder were replaced with diffusers.models.unet_2d_blocks, the error disappeared.

在大家的指导下，特别是 Neytiri7的提醒，解决了问题。思路和方法如下：一、from diffusers.models.unet_2d_blocks import CrossAttnDownBlock2D, CrossAttnUpBlock2D, DownBlock2D, UpBlock2D，找不到python库的模块，我就到python\Lib\site-packages\diffusers\models确实没有unet_2d_blocks块，最后在python\Lib\site-packages\diffusers\models\unets里面找到这一块；二、分析说明是这个模块发生了变化，只需要修改from就可以；三、在LCM中很多个文件中都有from diffusers.models.unet_2d_blocks，要逐一找到修改；四、修改内容很简单：将from diffusers.models.unet_2d_blocks修改成from diffusers.models.unets.unet_2d_blocks,问题完美解决。

I hope it will be fixed formally.
