# TrajLoomDatasets TrajLoomDatasets contains the released data bundles for TrajLoom, including videos, AllTracker-processed trajectories, and cache files used for dense future trajectory generation and benchmarking. The dataset is distributed as zip files at the repository root for easier upload and download. ## Repository layout on Hugging Face After downloading from Hugging Face, the root folder should look like this: ```text /TrajLoomDataset/ kubric_alltracker_s32.zip robotap_alltracker_s32.zip kinetics_alltracker_s32.zip kinetics_video.zip robotap_video.zip kubric_video.zip magicdata_video.zip magicdata_alltracker_s32.zip cache.zip README.md LICENSE ``` ## Quick download ### Option 1: clone the full dataset repository ```bash git lfs install git clone https://huggingface.co/datasets/zeweizhang/TrajLoomDatasets ``` ### Option 2: download with `hf` ```bash pip install -U "huggingface_hub[cli]" hf download zeweizhang/TrajLoomDatasets --repo-type dataset --local-dir /TrajLoomDataset ``` ## Quick unzip If the downloaded zip files are directly under `/TrajLoomDataset/`, run: ```bash cd /TrajLoomDataset for f in *.zip; do unzip -oq "$f" -d /TrajLoomDataset done ``` This restores each subset into its own root-level folder. ## Folder tree after extraction After unzipping, the folder layout becomes: ```text /TrajLoomDataset/ kubric_alltracker_s32/ robotap_alltracker_s32/ kinetics_alltracker_s32/ kinetics_video/ robotap_video/ kubric_video/ magicdata_video/ magicdata_alltracker_s32/ cache/ README.md LICENSE ``` ## Guided folder description ```text /TrajLoomDataset/ ├── kubric_alltracker_s32/ # AllTracker trajectory outputs for Kubric videos ├── robotap_alltracker_s32/ # AllTracker trajectory outputs for RoboTAP videos ├── kinetics_alltracker_s32/ # AllTracker trajectory outputs for Kinetics videos ├── kinetics_video/ # Kinetics video subset ├── robotap_video/ # RoboTAP video subset ├── kubric_video/ # Kubric-generated video subset ├── magicdata_video/ # MagicData video subset ├── magicdata_alltracker_s32/ # AllTracker trajectory outputs for MagicData videos ├── cache/ # Cached latents from TrajLoom-VAE from MagicData trajectory ├── README.md └── LICENSE ``` ## Notes - The zip files are distributed at the repository root to reduce the number of uploaded files. - The unzip command above keeps each subset in its own top-level folder. - You may delete the `.zip` files after extraction if you no longer need them. Optional cleanup: ```bash cd /TrajLoomDataset rm -f *.zip ``` ## License TrajLoomDatasets contains mixed-source materials. - Original TrajLoom-created materials are released under Apache-2.0 unless noted otherwise. - RoboTAP and TAP-Vid related materials follow their upstream CC BY 4.0 terms. - Kinetics-derived materials remain subject to the original source licenses of the underlying videos. - Kubric is Apache-2.0 software; original synthetic videos generated by us are released under Apache-2.0 unless third-party assets impose additional restrictions.
