Controlnet - v1.1 - InPaint Version

Controlnet v1.1 was released in lllyasviel/ControlNet-v1-1 by Lvmin Zhang.

This checkpoint is a conversion of the original checkpoint into diffusers format. It can be used in combination with Stable Diffusion, such as runwayml/stable-diffusion-v1-5.

For more details, please also have a look at the ? Diffusers docs.

ControlNet is a neural network structure to control diffusion models by adding extra conditions.

This checkpoint corresponds to the ControlNet conditioned on inpaint images.

Introduction

Controlnet was proposed in Adding Conditional Control to Text-to-Image Diffusion Models by Lvmin Zhang, Maneesh Agrawala.

The abstract reads as follows:

We present a neural network structure, ControlNet, to control pretrained large diffusion models to support additional input conditions. The ControlNet learns task-specific conditions in an end-to-end way, and the learning is robust even when the training dataset is small (< 50k). Moreover, training a ControlNet is as fast as fine-tuning a diffusion model, and the model can be trained on a personal devices. Alternatively, if powerful computation clusters are available, the model can scale to large amounts (millions to billions) of data. We report that large diffusion models like Stable Diffusion can be augmented with ControlNets to enable conditional inputs like edge maps, segmentation maps, keypoints, etc. This may enrich the methods to control large diffusion models and further facilitate related applications.

Example

It is recommended to use the checkpoint with Stable Diffusion v1-5 as the checkpoint has been trained on it. Experimentally, the checkpoint can be used with other diffusion models such as dreamboothed stable diffusion.

1. Let's install `diffusers` and related packages:

$ pip install diffusers transformers accelerate

2. Run code:

python import torch import os from diffusers.utils import loadimage from PIL import Image import numpy as np from diffusers import ( ControlNetModel, StableDiffusionControlNetPipeline, UniPCMultistepScheduler, ) checkpoint = "lllyasviel/controlv11psd15inpaint" originalimage = loadimage( "https://huggingface.co/lllyasviel/controlv11psd15inpaint/resolve/main/images/original.png" ) maskimage = loadimage( "https://huggingface.co/lllyasviel/controlv11psd15inpaint/resolve/main/images/mask.png" )

def makeinpaintcondition(image, imagemask): image = np.array(image.convert("RGB")).astype(np.float32) / 255.0 imagemask = np.array(imagemask.convert("L")) assert image.shape[0:1] == imagemask.shape[0:1], "image and imagemask must have the same image size" image[imagemask < 128] = -1.0 # set as masked pixel image = np.expanddims(image, 0).transpose(0, 3, 1, 2) image = torch.fromnumpy(image) return image

controlimage = makeinpaintcondition(originalimage, maskimage) prompt = "best quality" negativeprompt="lowres, bad anatomy, bad hands, cropped, worst quality" controlnet = ControlNetModel.frompretrained(checkpoint, torchdtype=torch.float16) pipe = StableDiffusionControlNetPipeline.frompretrained( "runwayml/stable-diffusion-v1-5", controlnet=controlnet, torchdtype=torch.float16 ) pipe.scheduler = UniPCMultistepScheduler.fromconfig(pipe.scheduler.config) pipe.enablemodelcpuoffload() generator = torch.manualseed(2) image = pipe(prompt, negativeprompt=negativeprompt, numinferencesteps=30, generator=generator, image=controlimage).images[0] image.save('images/output.png') ``` original mask inpaint_output
