The checkpoint is a distilled from https://huggingface.co./Lykon/dreamshaper-7 with our proposed Sub-path Linear Approximation Model, which reduces the number of inference steps to only between 2-4 steps.
First, install the latest version of the Diffusers library as well as peft, accelerate and transformers.
pip install --upgrade pip
pip install --upgrade diffusers transformers accelerate peft
We implement SLAM to be compatible with LCMScheduler. You can use SLAM just like you use LCM, with guidance_scale set to 1 constantly.
from diffusers import DiffusionPipeline
import torch
pipe = DiffusionPipeline.from_pretrained("alimama-creative/slam-dreamshaper7")
# To save GPU memory, torch.float16 can be used, but it may compromise image quality.
pipe.to(torch_device="cuda", torch_dtype=torch.float16)
prompt = "Self-portrait oil painting, a beautiful cyborg with golden hair, 8k"
num_inference_steps = 4
images = pipe(prompt=prompt, num_inference_steps=num_inference_steps, guidance_scale=1, lcm_origin_steps=50, output_type="pil").images
