| # 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 |
