# 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
```
