News

• 2024/06/15: 🎉🎉🎉 Release the first version on GitHub.
• 2024/06/15: ✨✨✨ Release some images and audios for inference testing on Huggingface.

Installation

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

conda create -n hallo python=3.10
  conda activate hallo

Install packages with pip

pip install -r requirements.txt
  pip install .

Besides, ffmpeg is also need:

apt-get install ffmpeg

Inference

The inference entrypoint script is scripts/inference.py. Before testing your cases, there are two preparations need to be completed:

Download pretrained models

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

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

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

Or you can download them separately from their source repo:

• hallo: Our checkpoints consist of denoising UNet, face locator, image & audio proj.
• audio_separator: Kim\_Vocal\_2 MDX-Net vocal removal model by KimberleyJensen. (_Thanks to runwayml_)
• insightface: 2D and 3D Face Analysis placed into pretrained_models/face_analysis/models/. (_Thanks to deepinsight_)
• face landmarker: Face detection & mesh model from mediapipe placed into pretrained_models/face_analysis/models.
• motion module: motion module from AnimateDiff. (_Thanks to guoyww_).
• sd-vae-ft-mse: Weights are intended to be used with the diffusers library. (_Thanks to stablilityai_)
• StableDiffusion V1.5: Initialized and fine-tuned from Stable-Diffusion-v1-2. (_Thanks to runwayml_)
• wav2vec: wav audio to vector model from Facebook.

Run inference

Simply to run the scripts/inference.py and pass source_image and driving_audio as input:

python scripts/inference.py --source_image your_image.png --driving_audio your_audio.wav

Animation results will be saved as ${PROJECT_ROOT}/.cache/output.mp4 by default. You can pass --output to specify the output file name.

For more options:

usage: inference.py [-h] [-c CONFIG] [--source_image SOURCE_IMAGE] [--driving_audio DRIVING_AUDIO] [--output OUTPUT] [--pose_weight POSE_WEIGHT]
                    [--face_weight FACE_WEIGHT] [--lip_weight LIP_WEIGHT] [--face_expand_ratio FACE_EXPAND_RATIO]
options:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
  --source_image SOURCE_IMAGE
                        source image
  --driving_audio DRIVING_AUDIO
                        driving audio
  --output OUTPUT       output video file name
  --pose_weight POSE_WEIGHT
                        weight of pose
  --face_weight FACE_WEIGHT
                        weight of face
  --lip_weight LIP_WEIGHT
                        weight of lip
  --face_expand_ratio FACE_EXPAND_RATIO
                        face region

Social Risks and Mitigations

The development of portrait image animation technologies driven by audio inputs poses social risks, such as the ethical implications of creating realistic portraits that could be misused for deepfakes. To mitigate these risks, it is crucial to establish ethical guidelines and responsible use practices. Privacy and consent concerns also arise from using individuals' images and voices. Addressing these involves transparent data usage policies, informed consent, and safeguarding privacy rights. By addressing these risks and implementing mitigations, the research aims to ensure the responsible and ethical development of this technology.
