This is the code for the CVPR 2018 paper Neural Kinematic Networks for Unsupervised Motion Retargetting by Ruben Villegas, Jimei Yang, Duygu Ceylan and Honglak Lee.
Please follow the instructions below to run the code:
Our method works with works with
- Linux
- NVIDIA Titan X GPU
- Tensorflow version 1.3.0
- pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.3.0-cp27-none-linux_x86_64.whl

Train data:
Firstly, create an account in the Mixamo website. Next, refer to Apendix D in our paper, and download the corresponding fbx animation files for each character folder in ./datasets/train/. Once the fbx files have been downloaded, run the following blender script to convert them into BVH files:
blender -b -P ./datasets/fbx2bvh.py
Finally, preprocess the bvh files into npy files by running the following command:
python ./datasets/preprocess.py
Test data (already preprocessed):
./datasets/download_test.sh
