# OOTDiffusion
This repository is the official implementation of OOTDiffusion

🤗 [Try out OOTDiffusion](https://huggingface.co/spaces/levihsu/OOTDiffusion) (Thanks to [ZeroGPU](https://huggingface.co/zero-gpu-explorers) for providing A100 GPUs)

Or [try our own demo](https://ootd.ibot.cn/) on RTX 4090 GPUs

Our model checkpoints trained on [VITON-HD](https://github.com/shadow2496/VITON-HD) (half-body) and [Dress Code](https://github.com/aimagelab/dress-code) (full-body) have been released

* 🤗 [Hugging Face link](https://huggingface.co/levihsu/OOTDiffusion)
* 📢📢 We support ONNX for [humanparsing](https://github.com/GoGoDuck912/Self-Correction-Human-Parsing) now. Most environmental issues should have been addressed : )
* Please download [clip-vit-large-patch14](https://huggingface.co/openai/clip-vit-large-patch14) into ***checkpoints*** folder
* We've only tested our code and models on Linux (Ubuntu 22.04)

## Installation
1. Clone the repository

```sh
git clone https://github.com/levihsu/OOTDiffusion
```

2. Create a conda environment and install the required packages

```sh
conda create -n ootd python==3.10
conda activate ootd
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2
pip install -r requirements.txt
```

## Inference
1. Half-body model

```sh
cd OOTDiffusion/run
python run_ootd.py --model_path <model-image-path> --cloth_path <cloth-image-path> --scale 2.0 --sample 4
```

2. Full-body model 

> Garment category must be paired: 0 = upperbody; 1 = lowerbody; 2 = dress

```sh
cd OOTDiffusion/run
python run_ootd.py --model_path <model-image-path> --cloth_path <cloth-image-path> --model_type dc --category 2 --scale 2.0 --sample 4
```
