Hugging Face Replicate ComfyUI visitors

We propose ResAdapter, a plug-and-play resolution adapter for enabling any diffusion model generate resolution-free images: no additional training, no additional inference and no style transfer.

Comparison examples between resadapter and dreamlike-diffusion-1.0.

Release

Quicktour

We provide a standalone example code to help you quickly use resadapter with diffusion models.

Comparison examples (640x384) between resadapter and dreamshaper-xl-1.0. Top: with resadapter. Bottom: without resadapter.

# pip install diffusers, transformers, accelerate, safetensors, huggingface_hub
import torch
from torchvision.utils import save_image
from safetensors.torch import load_file
from huggingface_hub import hf_hub_download
from diffusers import AutoPipelineForText2Image, DPMSolverMultistepScheduler

generator = torch.manual_seed(0)
prompt = "portrait photo of muscular bearded guy in a worn mech suit, light bokeh, intricate, steel metal, elegant, sharp focus, soft lighting, vibrant colors"
width, height = 640, 384

# Load baseline pipe
model_name = "lykon-models/dreamshaper-xl-1-0"
pipe = AutoPipelineForText2Image.from_pretrained(model_name, torch_dtype=torch.float16, variant="fp16").to("cuda")
pipe.scheduler = DPMSolverMultistepScheduler.from_config(pipe.scheduler.config, use_karras_sigmas=True, algorithm_type="sde-dpmsolver++")

# Inference baseline pipe
image = pipe(prompt, width=width, height=height, num_inference_steps=25, num_images_per_prompt=4, output_type="pt").images
save_image(image, f"image_baseline.png", normalize=True, padding=0)

# Load resadapter for baseline
resadapter_model_name = "resadapter_v1_sdxl"
pipe.load_lora_weights(
    hf_hub_download(repo_id="jiaxiangc/res-adapter", subfolder=resadapter_model_name, filename="pytorch_lora_weights.safetensors"), 
    adapter_name="res_adapter",
    ) # load lora weights
pipe.set_adapters(["res_adapter"], adapter_weights=[1.0])
pipe.unet.load_state_dict(
    load_file(hf_hub_download(repo_id="jiaxiangc/res-adapter", subfolder=resadapter_model_name, filename="diffusion_pytorch_model.safetensors")),
    strict=False,
    ) # load norm weights

# Inference resadapter pipe
image = pipe(prompt, width=width, height=height, num_inference_steps=25, num_images_per_prompt=4, output_type="pt").images
save_image(image, f"image_resadapter.png", normalize=True, padding=0)

Download

Models

We have released all resadapter weights, you can download resadapter models from Huggingface. The following is our resadapter model card:

resadapter_v2_sdxl 0.5M 256 <= x <= 1536 0.28 <= r <= 3.5 Download

resadapter_v1_sdxl_interpolation 0.5M 256 <= x <= 1024 0.5 <= r <= 2 Download

Hint1: We update the resadapter name format according to controlnet.

Hint2: If you want use resadapter with personalized diffusion models, you should download them from CivitAI.

Hint3: If you want use resadapter with ip-adapter, controlnet and lcm-lora, you should download them from Huggingface.

Hint4: Here is an installation guidance for preparing environment and downloading models.

Inference

If you want generate images in our inference script, you should install dependency libraries and download related models according to installation guidance. After filling in example configs, you can directly run this script.

python main.py --config /path/to/file

Local Gradio Demo

Run the following script:

# pip install peft, gradio, httpx==0.23.3
python app.py

Usage Tips

  1. If you are not satisfied with interpolation images, try to increase the alpha of resadapter to 1.0.
  2. If you are not satisfied with extrapolate images, try to choose the alpha of resadapter in 0.3 ~ 0.7.
  3. If you find the images with style conflicts, try to decrease the alpha of resadapter.
  4. If you find resadapter is not compatible with other accelerate lora, try to decrease the alpha of resadapter to 0.5 ~ 0.7.
