## Introduction 📖
This repo, named **LivePortrait**, contains the official PyTorch implementation of our paper [LivePortrait: Efficient Portrait Animation with Stitching and Retargeting Control](https://arxiv.org/pdf/2407.03168).
We are actively updating and improving this repository. If you find any bugs or have suggestions, welcome to raise issues or submit pull requests (PR) 💖.

## Getting Started 🏁
### 1. Clone the code and prepare the environment
```bash
git clone https://github.com/KwaiVGI/LivePortrait
cd LivePortrait

# create env using conda
conda create -n LivePortrait python==3.9
conda activate LivePortrait

# install dependencies with pip
# for Linux and Windows users
pip install -r requirements.txt
# for macOS with Apple Silicon users
pip install -r requirements_macOS.txt
```

**Note:** make sure your system has [FFmpeg](https://ffmpeg.org/download.html) installed, including both `ffmpeg` and `ffprobe`!

### 2. Download pretrained weights

The easiest way to download the pretrained weights is from HuggingFace:
```bash
# first, ensure git-lfs is installed, see: https://docs.github.com/en/repositories/working-with-files/managing-large-files/installing-git-large-file-storage
git lfs install
# clone and move the weights
git clone https://huggingface.co/KwaiVGI/LivePortrait temp_pretrained_weights
mv temp_pretrained_weights/* pretrained_weights/
rm -rf temp_pretrained_weights
```

Alternatively, you can download all pretrained weights from [Google Drive](https://drive.google.com/drive/folders/1UtKgzKjFAOmZkhNK-OYT0caJ_w2XAnib) or [Baidu Yun](https://pan.baidu.com/s/1MGctWmNla_vZxDbEp2Dtzw?pwd=z5cn). Unzip and place them in `./pretrained_weights`.

Ensuring the directory structure is as follows, or contains:
```text
pretrained_weights
├── insightface
│   └── models
│       └── buffalo_l
│           ├── 2d106det.onnx
│           └── det_10g.onnx
└── liveportrait
    ├── base_models
    │   ├── appearance_feature_extractor.pth
    │   ├── motion_extractor.pth
    │   ├── spade_generator.pth
    │   └── warping_module.pth
    ├── landmark.onnx
    └── retargeting_models
        └── stitching_retargeting_module.pth
```

### 3. Inference 🚀

#### Fast hands-on
```bash
# For Linux and Windows
python inference.py

# For macOS with Apple Silicon, Intel not supported, this maybe 20x slower than RTX 4090
PYTORCH_ENABLE_MPS_FALLBACK=1 python inference.py
```

If the script runs successfully, you will get an output mp4 file named `animations/s6--d0_concat.mp4`. This file includes the following results: driving video, input image or video, and generated result.

<p align="center">
  <img src="./docs/inference.gif" alt="image">
</p>

Or, you can change the input by specifying the `-s` and `-d` arguments:

```bash
# source input is an image
python inference.py -s assets/examples/source/s9.jpg -d assets/examples/driving/d0.mp4

# source input is a video ✨
python inference.py -s assets/examples/source/s13.mp4 -d assets/examples/driving/d0.mp4

# more options to see
python inference.py -h
```

#### Driving video auto-cropping 📢📢📢
To use your own driving video, we **recommend**: ⬇️
 - Crop it to a **1:1** aspect ratio (e.g., 512x512 or 256x256 pixels), or enable auto-cropping by `--flag_crop_driving_video`.
 - Focus on the head area, similar to the example videos.
 - Minimize shoulder movement.
 - Make sure the first frame of driving video is a frontal face with **neutral expression**.

Below is a auto-cropping case by `--flag_crop_driving_video`:
```bash
python inference.py -s assets/examples/source/s9.jpg -d assets/examples/driving/d13.mp4 --flag_crop_driving_video
```

If you find the results of auto-cropping is not well, you can modify the `--scale_crop_driving_video`, `--vy_ratio_crop_driving_video` options to adjust the scale and offset, or do it manually.

#### Motion template making
You can also use the auto-generated motion template files ending with `.pkl` to speed up inference, and **protect privacy**, such as:
```bash
python inference.py -s assets/examples/source/s9.jpg -d assets/examples/driving/d5.pkl # portrait animation
python inference.py -s assets/examples/source/s13.mp4 -d assets/examples/driving/d5.pkl # portrait video editing
```

### 4. Gradio interface 🤗

We also provide a Gradio <a href='https://github.com/gradio-app/gradio'><img src='https://img.shields.io/github/stars/gradio-app/gradio'></a> interface for a better experience, just run by:

```bash
# For Linux and Windows users (and macOS with Intel??)
python app.py

# For macOS with Apple Silicon users, Intel not supported, this maybe 20x slower than RTX 4090
PYTORCH_ENABLE_MPS_FALLBACK=1 python app.py
```

You can specify the `--server_port`, `--share`, `--server_name` arguments to satisfy your needs!

🚀 We also provide an acceleration option `--flag_do_torch_compile`. The first-time inference triggers an optimization process (about one minute), making subsequent inferences 20-30% faster. Performance gains may vary with different CUDA versions.
```bash
# enable torch.compile for faster inference
python app.py --flag_do_torch_compile
```
**Note**: This method is not supported on Windows and macOS.

**Or, try it out effortlessly on [HuggingFace](https://huggingface.co/spaces/KwaiVGI/liveportrait) 🤗**

### 5. Inference speed evaluation 🚀🚀🚀
We have also provided a script to evaluate the inference speed of each module:

```bash
# For NVIDIA GPU
python speed.py
```

Below are the results of inferring one frame on an RTX 4090 GPU using the native PyTorch framework with `torch.compile`:

| Model                             | Parameters(M) | Model Size(MB) | Inference(ms) |
|-----------------------------------|:-------------:|:--------------:|:-------------:|
| Appearance Feature Extractor      |     0.84      |       3.3      |     0.82      |
| Motion Extractor                  |     28.12     |       108      |     0.84      |
| Spade Generator                   |     55.37     |       212      |     7.59      |
| Warping Module                    |     45.53     |       174      |     5.21      |
| Stitching and Retargeting Modules |     0.23      |       2.3      |     0.31      |

*Note: The values for the Stitching and Retargeting Modules represent the combined parameter counts and total inference time of three sequential MLP networks.*

## Ethics Considerations 🛡️
Portrait animation technologies come with social risks, particularly the potential for misuse in creating deepfakes. To mitigate these risks, it’s crucial to follow ethical guidelines and adopt responsible usage practices. At present, the synthesized results contain visual artifacts that may help in detecting deepfakes. Please note that we do not assume any legal responsibility for the use of the results generated by this project.
