改问题为采用最新版本的diffusers引发的版本兼容问题，解决方案如下：
./custom_nodes/ComfyUI-layerdiffuse/lib_layerdiffusion/models.py文件中大约第10行
原码：
from diffusers.models.unet_2d_blocks import UNetMidBlock2D, get_down_block, get_up_block
修改为：
from diffusers.models.unets.unet_2d_blocks import UNetMidBlock2D, get_down_block, get_up_block
lib/python3.10/site-packages/modelscope/models/multi_modal/efficient_diffusion_tuning/control_sd_lora.py文件大约18行
原码：
from diffusers.models.unet_2d_blocks import \
get_down_block as get_down_block_default
修改为：
from diffusers.models.unets.unet_2d_blocks import \
get_down_block as get_down_block_default
