🔧️ Framework

⚙️ 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 -r requirements.txt
  pip install .

Besides, ffmpeg is also needed:

  apt-get install ffmpeg

🗝️️ Usage

The entry point for inference is scripts/inference.py. Before testing your cases, two preparations need to be completed:

Download all required pretrained models.
Prepare source image and driving audio pairs.
Run inference.

📥 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/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. (Thanks to KimberleyJensen)
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.

Finally, these pretrained models should be organized as follows:

./pretrained_models/
|-- audio_separator/
|   `-- Kim_Vocal_2.onnx
|-- face_analysis/
|   `-- models/
|       |-- face_landmarker_v2_with_blendshapes.task  # face landmarker model from mediapipe
|       |-- 1k3d68.onnx
|       |-- 2d106det.onnx
|       |-- genderage.onnx

    |   |-- special_tokens_map.json
    |   |-- tokenizer_config.json
    |   `-- vocab.json

🛠️ Prepare Inference Data

Hallo has a few simple requirements for input data:

For the source image:

It should be cropped into squares.
The face should be the main focus, making up 50%-70% of the image.
The face should be facing forward, with a rotation angle of less than 30° (no side profiles).

For the driving audio:

It must be in WAV format.
It must be in English since our training datasets are only in this language.
Ensure the vocals are clear; background music is acceptable.

We have provided some samples for your reference.

🎮 Run Inference

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

python scripts/inference.py --source_image examples/reference_images/1.jpg --driving_audio examples/driving_audios/1.wav

Animation results will be saved as ${PROJECT_ROOT}/.cache/output.mp4 by default. You can pass --output to specify the output file name. You can find more examples for inference at examples folder.

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.
