Hallo2: Long-Duration and High-Resolution Audio-driven Portrait Image Animation

⚙️ Installation

System requirement: Ubuntu 20.04/Ubuntu 22.04, Cuda 12.1
Tested GPUs: A100

Create conda environment:

  conda create -n hallo python=3.10
  conda activate hallo

Install packages with pip

  pip install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2 --index-url https://download.pytorch.org/whl/cu118
  pip install -r requirements.txt

Besides, ffmpeg is also needed:

  apt-get install ffmpeg

📥 Download Pretrained Models

You can easily get all pretrained models required by inference from our HuggingFace repo.

Clone the pretrained models into ${PROJECT_ROOT}/pretrained_models directory by cmd below:

git lfs install
git clone https://huggingface.co/fudan-generative-ai/hallo2 pretrained_models

Or you can download them separately from their source repo:

hallo2: Our checkpoint of video super-resolution.
facelib: pretrained face parse models
realesrgan: background upsample model
CodeFormer: pretrained Codeformer model, it's optional to download it, only if you want to train our video super-resolution model from scratch

Finally, these pretrained models should be organized as follows:

./pretrained_models/
|-- CodeFormer/
|   |-- codeformer.pth
|   `-- vqgan_code1024.pth
|-- facelib
|   |-- detection_mobilenet0.25_Final.pth
|   |-- detection_Resnet50_Final.pth
|   |-- parsing_parsenet.pth
|   |-- yolov5l-face.pth
|   `-- yolov5n-face.pth
|-- hallo2
|   `-- net_g.pth
`-- realesrgan
    `-- RealESRGAN_x2plus.pth

🎮 Run Inference

High-Resolution animation

Simply to run the scripts/video_sr.py and pass input_path and output_path:

python scripts/video_sr.py --input_path [input_video] --output_path [output_dir] --bg_upsampler realesrgan --face_upsample -w 1 -s 4

Animation results will be saved at output_dir.

For more options:

usage: video_sr.py [-h] [-i INPUT_PATH] [-o OUTPUT_PATH] [-w FIDELITY_WEIGHT] [-s UPSCALE] [--has_aligned] [--only_center_face] [--draw_box]
                   [--detection_model DETECTION_MODEL] [--bg_upsampler BG_UPSAMPLER] [--face_upsample] [--bg_tile BG_TILE] [--suffix SUFFIX]

options:
  -h, --help            show this help message and exit
  -i INPUT_PATH, --input_path INPUT_PATH
                        Input video
  -o OUTPUT_PATH, --output_path OUTPUT_PATH
                        Output folder. 
  -w FIDELITY_WEIGHT, --fidelity_weight FIDELITY_WEIGHT
                        Balance the quality and fidelity. Default: 0.5
  -s UPSCALE, --upscale UPSCALE
                        The final upsampling scale of the image. Default: 2
  --has_aligned         Input are cropped and aligned faces. Default: False
  --only_center_face    Only restore the center face. Default: False
  --draw_box            Draw the bounding box for the detected faces. Default: False
  --detection_model DETECTION_MODEL
                        Face detector. Optional: retinaface_resnet50, retinaface_mobile0.25, YOLOv5l, YOLOv5n. Default: retinaface_resnet50
  --bg_upsampler BG_UPSAMPLER
                        Background upsampler. Optional: realesrgan
  --face_upsample       Face upsampler after enhancement. Default: False
  --bg_tile BG_TILE     Tile size for background sampler. Default: 400
  --suffix SUFFIX       Suffix of the restored faces. Default: None

Training

prepare data for training

We use the VFHQ dataset for training, you can download from its homepage. Then updata dataroot_gt in ./configs/train/video_sr.yaml.

training

Start training with the following command:

python -m torch.distributed.launch --nproc_per_node=8 --master_port=4652 \
basicsr/train.py -opt ./configs/train/video_sr.yaml \
--launcher pytorch
