InstantIR Model Card

InstantIR is a novel single-image restoration model designed to resurrect your damaged images, delivering extrem-quality yet realistic details. You can further boost InstantIR performance with additional text prompts, even achieve customized editing!

Usage

1. Clone the github repo

git clone https://github.com/JY-Joy/InstantIR.git
cd InstantIR

2. Download model weights

You can directly download InstantIR weights in this repository, or you can download them using python script:

from huggingface_hub import hf_hub_download
hf_hub_download(repo_id="InstantX/InstantIR", filename="models/adapter.pt", local_dir=".")
hf_hub_download(repo_id="InstantX/InstantIR", filename="models/aggregator.pt", local_dir=".")
hf_hub_download(repo_id="InstantX/InstantIR", filename="models/previewer_lora_weights.bin", local_dir=".")

3. Load InstantIR with 🧨 diffusers

# !pip install diffusers opencv-python transformers accelerate
import torch
from PIL import Image

from diffusers import DDPMScheduler
from schedulers.lcm_single_step_scheduler import LCMSingleStepScheduler

from module.ip_adapter.utils import load_adapter_to_pipe
from pipelines.sdxl_instantir import InstantIRPipeline

# prepare models under ./models
instantir_path = f'./models'

# load pretrained models
pipe = InstantIRPipeline.from_pretrained('stabilityai/stable-diffusion-xl-base-1.0', torch_dtype=torch.float16)

# load adapter
load_adapter_to_pipe(
    pipe,
    f"{instantir_path}/adapter.pt",
    image_encoder_or_path = 'facebook/dinov2-large',
)

# load previewer lora
pipe.prepare_previewers(instantir_path)
pipe.scheduler = DDPMScheduler.from_pretrained('stabilityai/stable-diffusion-xl-base-1.0', subfolder="scheduler")
lcm_scheduler = LCMSingleStepScheduler.from_config(pipe.scheduler.config)

# load aggregator weights
pretrained_state_dict = torch.load(f"{instantir_path}/aggregator.pt")
pipe.aggregator.load_state_dict(pretrained_state_dict)

# send to GPU and fp16
pipe.to(device='cuda', dtype=torch.float16)
pipe.aggregator.to(device='cuda', dtype=torch.float16)

Then, you can restore your broken images with:

# load a broken image
low_quality_image = Image.open('path/to/your-image').convert("RGB")

# InstantIR restoration
image = pipe(
    image=low_quality_image,
    previewer_scheduler=lcm_scheduler,
).images[0]

Inference Examples
This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social visibility and check back later, or deploy to Inference Endpoints (dedicated) instead.
