OMG + LORA :

OMG + InstantID:

TL; DR: OMG is a framework for multi-concept image generation, supporting character and style LoRAs on Civitai.com. It also can be combined with InstantID for multiple IDs with using a single image for each ID.

Introduction of OMG: A tool for high-quality multi-character image generation.

Trailor Demo: A short trailor "Home Defense" created by using OMG + SVD.

🏷️ Change Log

[2023/3/22] 🔥 We release the Hugging space for OMG + InstantID. Support ID personalization with a single image.
[2023/3/19] 🔥 We release the technical report and Hugging space for OMG-LoRAs
[2023/3/18] 🔥 We release the source code and gradio demo of OMG.

🔆 Introduction

1. OMG + LoRA (ID with multiple images)

2. OMG + InstantID (ID with single image)

3. OMG + ControlNet (Layout Control )

4. OMG + style LoRAs (Style Control)

🔧 Dependencies and Installation

The code requires python==3.10.6, as well as pytorch==2.0.1 and torchvision==0.15.2. Please follow the instructions here to install both PyTorch and TorchVision dependencies. Installing both PyTorch and TorchVision with CUDA support is strongly recommended.

conda create -n OMG python=3.10.6
conda activate OMG
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2
pip install -r requirements.txt
pip install git+https://github.com/facebookresearch/segment-anything.git

For Visual comprehension, you can choose YoloWorld + EfficientViT SAM or GroundingDINO + SAM

1. (Recommend) YoloWorld + EfficientViT SAM:

pip install inference[yolo-world]==0.9.13
pip install  onnxsim==0.4.35

1. (Optional) If you can not install inference[yolo-world]. You can install GroundingDINO for visual comprehension.

GroundingDINO requires manual installation.

Run this so the environment variable will be set under current shell.

export CUDA_HOME=/path/to/cuda-11.3

In this example, /path/to/cuda-11.3 should be replaced with the path where your CUDA toolkit is installed.

git clone https://github.com/IDEA-Research/GroundingDINO.git

cd GroundingDINO/

pip install -e .

More installation details can be found in GroundingDINO

Put ViT-B-32.pt (download from openai) to ~/.cache/clip/ViT-B-32.pt. If using YoloWorld, put yolo-world.pt to /tmp/cache/yolo_world/l/yolo-world.pt.

Or you can manually set the checkpoint path as follows:

python inference_lora.py  \
--pretrained_sdxl_model <path to stable-diffusion-xl-base-1.0> \
--controlnet_checkpoint <path to controlnet-openpose-sdxl-1.0> \
--efficientViT_checkpoint <path to efficientViT-SAM-XL1> \
--dino_checkpoint <path to GroundingDINO> \
--sam_checkpoint <path to sam> \
--lora_path <Lora path to character1|Lora path to character1> \
--style_lora <Path to style LoRA>

For OMG + InstantID:

python inference_instantid.py  \
--pretrained_model <path to stable-diffusion-xl-base-1.0> \
--controlnet_path <path to InstantID controlnet> \
--face_adapter_path <path to InstantID face adapter> \
--efficientViT_checkpoint <path to efficientViT-SAM-XL1> \
--dino_checkpoint <path to GroundingDINO> \
--sam_checkpoint <path to sam> \
--antelopev2_path <path to antelopev2> \
--style_lora <Path to style LoRA>

💻 Usage
