## ⚙️ Framework
<img src="assets/overview.png" alt="Image 1" width="100%">


We present PersonaLive, a `real-time` and `streamable` diffusion framework capable of generating `infinite-length` portrait animations on a single `12GB GPU`.


## 🚀 Getting Started
### 🛠 Installation
```
# clone this repo
git clone https://github.com/GVCLab/PersonaLive
cd PersonaLive

# Create conda environment
conda create -n personalive python=3.10
conda activate personalive

# Install packages with pip
pip install -r requirements_base.txt
```

### ⏬ Download weights
Option 1: Download pre-trained weights of base models and other components ([sd-image-variations-diffusers](https://huggingface.co/lambdalabs/sd-image-variations-diffusers) and [sd-vae-ft-mse](https://huggingface.co/stabilityai/sd-vae-ft-mse)). You can run the following command to download weights automatically:
    
```bash
python tools/download_weights.py
```

Option 2: Download pre-trained weights into the `./pretrained_weights` folder from one of the below URLs:
    
<a href='https://drive.google.com/drive/folders/1GOhDBKIeowkMpBnKhGB8jgEhJt_--vbT?usp=drive_link'><img src='https://img.shields.io/badge/Google%20Drive-5B8DEF?style=for-the-badge&logo=googledrive&logoColor=white'></a> <a href='https://pan.baidu.com/s/1DCv4NvUy_z7Gj2xCGqRMkQ?pwd=gj64'><img src='https://img.shields.io/badge/Baidu%20Netdisk-3E4A89?style=for-the-badge&logo=baidu&logoColor=white'></a> <a href='https://modelscope.cn/models/huaichang/PersonaLive'><img src='https://img.shields.io/badge/ModelScope-624AFF?style=for-the-badge&logo=alibabacloud&logoColor=white'></a> <a href='https://huggingface.co/huaichang/PersonaLive'><img src='https://img.shields.io/badge/HuggingFace-E67E22?style=for-the-badge&logo=huggingface&logoColor=white'></a>

Finally, these weights should be organized as follows:
```

├── onnx
│   ├── unet_opt
│   │   ├── unet_opt.onnx
│   │   └── unet_opt.onnx.data
│   └── unet
├── personalive
│   ├── denoising_unet.pth
│   ├── motion_encoder.pth
│   ├── motion_extractor.pth
│   ├── pose_guider.pth
│   ├── reference_unet.pth
│   └── temporal_module.pth
├── sd-vae-ft-mse
│   ├── diffusion_pytorch_model.bin
│   └── config.json
├── sd-image-variations-diffusers
│   ├── image_encoder
│   │   ├── pytorch_model.bin
│   │   └── config.json
│   ├── unet
│   │   ├── diffusion_pytorch_model.bin
│   │   └── config.json
│   └── model_index.json
└── tensorrt
    └── unet_work.engine
```

### 🎞️ Offline Inference
```
python inference_offline.py
```
⚠️ Note for RTX 50-Series (Blackwell) Users: xformers is not yet fully compatible with the new architecture. To avoid crashes, please disable it by running:
```
python inference_offline.py --use_xformers False
```

### 📸 Online Inference
#### 📦 Setup Web UI
```
# install Node.js 18+
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
nvm install 18

cd webcam
source start.sh
```

#### 🏎️ Acceleration (Optional)
Converting the model to TensorRT can significantly speed up inference (~ 2x ⚡️). Building the engine may take about `20 minutes` depending on your device. Note that TensorRT optimizations may lead to slight variations or a small drop in output quality.
```
pip install -r requirements_trt.txt

python torch2trt.py
```
*The provided TensorRT model is from an `H100`. We recommend `ALL users` (including H100 users) re-run `python torch2trt.py` locally to ensure best compatibility.*

#### ▶️ Start Streaming
```
python inference_online.py --acceleration none (for RTX 50-Series) or xformers or tensorrt
```
Then open `http://0.0.0.0:7860` in your browser. (*If `http://0.0.0.0:7860` does not work well, try `http://localhost:7860`)

**How to use**: Upload Image ➡️ Fuse Reference ➡️ Start Animation ➡️ Enjoy! 🎉

**Regarding Latency**: Latency varies depending on your device's computing power. You can try the following methods to optimize it:

1. Lower the "Driving FPS" setting in the WebUI to reduce the computational workload.
2. You can increase the multiplier (e.g., set to `num_frames_needed * 4` or higher) to better match your device's inference speed. https://github.com/GVCLab/PersonaLive/blob/6953d1a8b409f360a3ee1d7325093622b29f1e22/webcam/util.py#L73
