yujiepan/dreamshaper-8-lcm-openvino

This model applies latent-consistency/lcm-lora-sdv1-5 on base model Lykon/dreamshaper-8, and is converted as OpenVINO FP16 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 laptop, 4k, details'
images = pipeline(prompt=prompt, num_inference_steps=8, guidance_scale=1.0).images

Scripts

The model is generated by the following codes:

torch_pipeline = AutoPipelineForText2Image.from_pretrained(
    base_model_id, torch_dtype=torch.float16, variant="fp16")

    torch_pipeline.scheduler.config)
# load and fuse lcm lora
torch_pipeline.load_lora_weights(adapter_id)
