Usage
# Auto-download (integrated into training pipeline)
# Just set retargeting_method: gmr in your config - caches download automatically.
# Manual download
uv run musclemimic-download-gmr-caches --dataset-group AMASS_BIMANUAL_TRAIN_MOTIONS --env-name MyoBimanualArm
# Python API
from musclemimic.utils.gmr_cache import download_gmr_dataset_group
downloaded_paths = download_gmr_dataset_group(
dataset_group="AMASS_BIMANUAL_TRAIN_MOTIONS",
env_name="BimanualMuscle",
)
File Format
Each .npz file contains retargeted motion data with arrays:
qpos, qvel, xpos, xquat, cvel, subtree_com, site_xpos, site_xmat,
plus metadata (joint_names, body_names, site_names, frequency, split_points).
Sources and licenses
AMASS subset
Files outside MyoBimanualArm/gmr/ULTRA_MOCAP/ are derived from the
AMASS dataset. Please comply with the AMASS
license terms when using those files.
ULTRA-MoCap subset
MyoBimanualArm/gmr/ULTRA_MOCAP/<subject>/<trial>.npz contains 208
MyoBimanualArm trajectories retargeted from ULTRA-MoCap subjects P01-P13.
Each trajectory has an adjacent .metadata.json file recording its source
SHA-256, fitting provenance, pose prior, and root-initialization validation.
The ULTRA-MoCap subset is derived from the official ULTRA-MoCap v1 dataset, released under CC BY 4.0. It is not derived from AMASS. Please cite the original release:
