# IDPP-Data

Video archives for **IDPP** / **SVD** physics-benchmark reproduction: **friction**, **viscosity**, and **elasticity**, each with **absolute** and **relative** splits (train / test1 / test2 / test3 where applicable).

**Repository:** [`Oliver-Ma/IDPP-Data`](https://huggingface.co/datasets/Oliver-Ma/IDPP-Data)  
**Snapshot (README revision):** 2026-04-12 — documents **26** `.zip` blobs under `video_zips/` (mirroring local `dataset/<lane>/`).

## Important: archives, not frame folders

Everything under **`video_zips/`** is a **`.zip` file**. Training and evaluation code (e.g. WebVid-style loaders) expect a **directory** as `data_dir`. **Unzip** each bundle you need, then point `data_dir` at the **extracted folder** (usually the top-level directory inside the zip).

Example:

```bash
huggingface-cli download Oliver-Ma/IDPP-Data --repo-type dataset \
  --local-dir ./idpp_data
unzip ./idpp_data/video_zips/friction_absolute/4.29_friction_synthetic_test1.zip -d ./idpp_unpacked
# Then set data_dir to the inner folder that contains the rgb/mp4 tree.
```

Cross-check names and semantics with the project **`data_global_map.md`** (paths and splits).

**Notes**

- **Friction** `7.18_*_train.zip` under `friction_*` are the **test3-related train / finetune** style bundles (two zips per abs/rel lane); align with your paper / config naming.
- **Viscosity absolute** includes `7.15_new_viscosity_video_clips_16frames_merged.zip` (16-frame variant). If your paper uses the **152-frame merged** absolute test3 split, confirm against **`data_global_map.md`** and obtain that bundle from the canonical genesis copy if it is not in this repo.

## Environment variable

For download helpers in the public code tree:

```bash
export HF_SVD_DATA_REPO=Oliver-Ma/IDPP-Data
```

## Code

- Upstream / paper code: [idpp](https://github.com/xianzhengma/idpp).
- HF staging and bulk zip upload scripts live under `SVD_public/` in the reproduction tree (`docs/HF_DATASET_UPLOAD.md`, `scripts/upload_idpp_hub_zips.py`, `scripts/sbatch_upload_idpp_hub_zips.sh`).

## Maintainer upload

To refresh **this README** or re-push zips from a machine with a write token:

```bash
export HF_TOKEN=...   # never commit
huggingface-cli upload Oliver-Ma/IDPP-Data \
  /path/to/SVD_public/docs/IDPP_Data_README.md README.md \
  --repo-type dataset \
  --commit-message "Update dataset README"
```

Or from `SVD_public`: `python scripts/upload_idpp_hub_zips.py --no-readme` for zips only; omit `--no-readme` to also push README (default).
