# catvton-flux

An state-of-the-art virtual try-on solution that combines the power of [CATVTON](https://arxiv.org/abs/2407.15886) (Contrastive Appearance and Topology Virtual Try-On) with Flux fill inpainting model for realistic and accurate clothing transfer.
Also inspired by [In-Context LoRA](https://arxiv.org/abs/2410.23775) for prompt engineering.

## Model Weights
LORA weights in Hugging Face: 🤗 [catvton-flux-alpha](https://huggingface.co/xiaozaa/catvton-flux-alpha)
Fine-tuning weights in Hugging Face: 🤗 [catvton-flux-lora-alpha](https://huggingface.co/xiaozaa/catvton-flux-lora-alpha)
The model weights are trained on the [VITON-HD](https://github.com/shadow2496/VITON-HD) dataset.

## Prerequisites
Make sure you are runing the code with VRAM >= 40GB. (I run all my experiments on a 80GB GPU, lower VRAM will cause OOM error. Will support lower VRAM in the future.)

```bash
bash
conda create -n flux python=3.10
conda activate flux
pip install -r requirements.txt
huggingface-cli login
```

## Usage

Run the following command to try on an image:

LORA version:
```bash
python tryon_inference_lora.py \
--image ./example/person/00008_00.jpg \
--mask ./example/person/00008_00_mask.png \
--garment ./example/garment/00034_00.jpg \
--seed 4096 \
--output_tryon test_lora.png \
--steps 30
```

Fine-tuning version:
```bash
python tryon_inference.py \
--image ./example/person/00008_00.jpg \
--mask ./example/person/00008_00_mask.png \
--garment ./example/garment/00034_00.jpg \
--seed 42 \
--output_tryon test.png \
--steps 30
```

Run the following command to start a gradio demo:
```bash
python app.py
```

## TODO:
- [x] Release the FID score
- [x] Add gradio demo
- [ ] Release updated weights with better performance
- [x] Train a smaller model
- [ ] Support comfyui
