## 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

# 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 [`git`](https://git-scm.com/), [`conda`](https://anaconda.org/anaconda/conda), and [`FFmpeg`](https://ffmpeg.org/download.html) installed. For details on FFmpeg installation, see [**how to install FFmpeg**](assets/docs/how-to-install-ffmpeg.md).

### 2. Download pretrained weights 📥

The easiest way to download the pretrained weights is from HuggingFace:
```bash
# !pip install -U "huggingface_hub[cli]"
huggingface-cli download KwaiVGI/LivePortrait --local-dir pretrained_weights --exclude "*.git*" "README.md" "docs"
```

If you cannot access to Huggingface, you can use [hf-mirror](https://hf-mirror.com/) to download:
```bash
# !pip install -U "huggingface_hub[cli]"
export HF_ENDPOINT=https://hf-mirror.com
huggingface-cli download KwaiVGI/LivePortrait --local-dir pretrained_weights --exclude "*.git*" "README.md" "docs"
```

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) (WIP). Unzip and place them in `./pretrained_weights`.

Ensuring the directory structure is as or contains [**this**](assets/docs/directory-structure.md).

### 3. Inference 🚀

#### Fast hands-on (humans) 👤
```bash
# For Linux and Windows users
python inference.py

# For macOS users with Apple Silicon (Intel is not tested). NOTE: 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="./assets/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
```

#### Fast hands-on (animals) 🐱🐶
Animals mode is ONLY tested on Linux with NVIDIA GPU.

You need to build an OP named `MultiScaleDeformableAttention` first, which is used by [X-Pose](https://github.com/IDEA-Research/X-Pose), a general keypoint detection framework.
```bash
cd src/utils/dependencies/XPose/models/UniPose/ops
python setup.py build install
cd - # equal to cd ../../../../../../../
```

Then
```bash
python inference_animals.py -s assets/examples/source/s39.jpg -d assets/examples/driving/wink.pkl --driving_multiplier 1.75 --no_flag_stitching
```
If the script runs successfully, you will get an output mp4 file named `animations/s39--wink_concat.mp4`.

#### Driving video auto-cropping 📢📢📢
> [!IMPORTANT]
> 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 # humans mode

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

We also provide a Gradio interface of animals mode, which is only tested on Linux with NVIDIA GPU:
```bash
python app_animals.py # animals mode 🐱🐶
```

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
```

The results are [**here**](./assets/docs/speed.md).
