Framework

Installation

• System requirement: Ubuntu20.04
• Tested GPUs: A100

Create conda environment:

  conda create -n champ python=3.10
  conda activate champ

Install packages with pip:

  pip install -r requirements.txt

Download pretrained models

1. Download pretrained weight of base models:

   • StableDiffusion V1.5
   • sd-vae-ft-mse
   • image_encoder

2. Download our checkpoints:
   Our checkpoints consist of denoising UNet, guidance encoders, Reference UNet, and motion module.

Finally, these pretrained models should be organized as follows:

./pretrained_models/
|-- champ
|   |-- denoising_unet.pth
|   |-- guidance_encoder_depth.pth
|   |-- guidance_encoder_dwpose.pth
|   |-- guidance_encoder_normal.pth
|   |-- guidance_encoder_semantic_map.pth
|   |-- reference_unet.pth
|   `-- motion_module.pth
|-- image_encoder
|   |-- config.json
|   `-- pytorch_model.bin
|-- sd-vae-ft-mse
|   |-- config.json
|   |-- diffusion_pytorch_model.bin
|   `-- diffusion_pytorch_model.safetensors
`-- stable-diffusion-v1-5
    |-- feature_extractor
    |   `-- preprocessor_config.json
    |-- model_index.json
    |-- unet
    |   |-- config.json
    |   `-- diffusion_pytorch_model.bin
    `-- v1-inference.yaml

Inference

We have provided several sets of example data for inference. Please first download and place them in the example_data folder. Here is the command for inference:

  python inference.py --config configs/inference.yaml

Animation results will be saved in results folder. You can change the reference image or the guidance motion by modifying inference.yaml.

You can also extract the driving motion from any videos and then render with Blender. We will later provide the instructions and scripts for this.
