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

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"]
