yujiepan/dreamshaper-8-lcm-openvino
This model applies latent-consistency/lcm-lora-sdv1-5 to base model Lykon/dreamshaper-8, and is converted to OpenVINO format.
Usage
from optimum.intel.openvino.modeling_diffusion import OVStableDiffusionPipeline
pipeline = OVStableDiffusionPipeline.from_pretrained(
'yujiepan/dreamshaper-8-lcm-openvino',
device='CPU',
)
prompt = 'Cute Dog Typing at a Typewriter German Style'
images = pipeline(prompt=prompt, num_inference_steps=8, guidance_scale=1.0).images
TODO
- The fp16 base model is converted to openvino in fp32, which is unnecessary.
Scripts
The model is generated by the following codes:
import torch
from diffusers import AutoPipelineForText2Image, LCMScheduler

base_model_id = "Lykon/dreamshaper-8"
adapter_id = "latent-consistency/lcm-lora-sdv1-5"
save_torch_folder = './dreamshaper-8-lcm'
save_ov_folder = './dreamshaper-8-lcm-openvino'
torch_pipeline = AutoPipelineForText2Image.from_pretrained(
base_model_id, torch_dtype=torch.float16, variant="fp16")
torch_pipeline.scheduler = LCMScheduler.from_config(
torch_pipeline.scheduler.config)
# load and fuse lcm lora
torch_pipeline.load_lora_weights(adapter_id)
