Installation

To setup the environment:

cd MotionMixer
conda create -n MotionMixer python=3.8.8
conda activate MotionMixer
pip install -r requirements.txt

Data

Due to licensing it is not possible to provide any data. Please refer to STSGCN for the preparation of the dataset files.

Training

To train the model on h36m or amass, you can use the following commands:

python h36m/train_mixer_h36m.py --input_n 10 --output_n 25 --skip_rate 1 

python amass/train_mixer_amass.py --input_n 10 --output_n 25 --skip_rate 5 

Evaluation

To test the pretrained models, you can use the following commands:

python h36m/test_mixer_h36m.py --input_n 10 --output_n 25 --skip_rate 1 

python amass/test_mixer_amass.py --input_n 10 --output_n 25 --skip_rate 5 

Models

We release the pretrained models for academic purpose. You can download them from Google Drive. Unzip the .zip file in the /checkpoints directory.
