# Krishi Vaidya Bouncer Dataset (WebDataset)

Hub-native sharded WebDataset export for large-scale object detection training and streaming.

## Format

- `train/train-*.tar` and `val/val-*.tar` store sharded samples for streaming-friendly access.
- Each sample is written as `<sample_id>.jpg` plus `<sample_id>.json` inside the TAR shard.
- JSON records keep canonical COCO-style `bbox` annotations in pixel `xywh` form.
- The canonical local dataset and derived YOLO export remain the source-of-truth build artifacts in this repo.

## Load

```python
from datasets import load_dataset

ds = load_dataset("webdataset", data_files={"train": "train/*.tar", "val": "val/*.tar"}, split="train")
sample = ds[0]
image = sample["jpg"]
annotation = sample["json"]
```

## Splits

- Train: 27,454 samples across 3 shards
- Val: 3,527 samples across 1 shards
