# NuPlan mini sample (VADv2-ready)
This dataset contains a single NuPlan mini log converted into the VADv2 training/evaluation format.

2021.05.12.22.00.38_veh-35_01008_01518.pkl # Raw converter output

```
The `annotations/*.pkl` file can be plugged directly into
`adzoo/vad/configs/VAD/VADv2_voca4096_mini_config.py` after setting `data_root` to
`data/nuplan/dataset`.
## Provenance & Conversion
- Source: `motional-nuplan/public/nuplan-v1.1/` on AWS S3 (mini split).
- Conversion: [`Nuplan-VAD-DataGen`](https://github.com/priest-yang/Nuplan-VAD-DataGen)
executed in a Python 3.10 environment.
- Only the log `2021.05.12.22.00.38_veh-35_01008_01518` is fully materialised (cameras + lidar).
## Notes
- Map annotations (`annotations/us-nv-las-vegas-strip_map.json`) are provided in both
the original converter output and the `annotations` directory.
- The `maps/` directory includes the full NuPlan map bundle so that map APIs work
without additional downloads.
- The camera folders (8x CAM_*) are included. Due to the Hub's per-directory limit (10k files), the `MergedPointCloud` lidar frames are **not** part of this snapshot; the paths remain in the annotations so you can drop the original files into `nuplan_data/nuplan-v1.1/sensor_blobs/2021.05.12.22.00.38_veh-35_01008_01518/MergedPointCloud/` if you need them.
- The mini split SQLite DB is the only one required for this log; additional DB files from the
mini bundle are not included to keep the footprint small (~37 GB total).
## Usage
1. Download the dataset and place it under your project root.
2. Point `data_root` / `ann_file_*` in the VADv2 config to the paths above.
3. Ensure the environment uses NumPy ≥ 2.0 to read the pickled infos (or add a compatibility shim).
