# PRIMO Bench JSON

This repository contains JSON annotations for **PRIMO**.

## What Is Included

- `raw_json/`: original JSON files copied from the PRIMO release layout
- `jsonl/`: flattened JSONL shards for better Hugging Face Data Studio preview
- `jsonl_subsets/`: subset-specific JSONL shards used by Dataset Viewer config selector
- `summary.json`: row/shard metadata generated at build time

## Split Type

- Task: Evaluation / Benchmark
- Source pattern: `primo-bench/*/{id,ood}.json`

## Media Mapping

This repo stores annotations only.

Media files (videos/frames) should be prepared in a local folder like:

- `./primo-video/...`

The `path`, `init_frame_path`, and `current_frame_path` fields are expected to resolve against your local `PRIMO-Data` root.

## Quick Load Example

```python
import json
from pathlib import Path

root = Path(".")
jsonl_dir = root / "jsonl"
rows = []
for fp in sorted(jsonl_dir.glob("part-*.jsonl")):
    with fp.open("r", encoding="utf-8") as f:
        for line in f:
            rows.append(json.loads(line))
print(len(rows))
```

## Build Metadata

- Total rows: **23704**
- Shards: **1**
- Shard size: **50000**

## Viewer Subsets

The Hugging Face Dataset Viewer subset selector maps to these configs:

- `all`
- `agibot-id`
- `agibot-ood`
- `behavior-1k-id`
- `behavior-1k-ood`
- `real-humanoid-ood`
- `robotwin-id`
- `robotwin-ood`
