## Usage |
|
|
|
|
|
### With LibreYOLO |
|
|
|
|
|
```python |
|
|
from libreyolo import LIBREYOLO |
|
|
|
|
|
# Load a model |
|
|
model = LIBREYOLO(model_path="libreyoloXnano.pt") |
|
|
|
|
|
# Train on this dataset |
|
|
model.train(data='path/to/data.yaml', epochs=100) |
|
|
``` |
|
|
|
|
|
### Download from HuggingFace |
|
|
|
|
|
```python |
|
|
from huggingface_hub import snapshot_download |
|
|
|
|
|
# Download the dataset |
|
|
snapshot_download( |
|
|
repo_id="Libre-YOLO/marbles", |
|
|
repo_type="dataset", |
|
|
local_dir="./marbles" |
|
|
) |

|
## Label Format |
|
|
|
|
|
Labels are in YOLO format (one `.txt` file per image): |
|
|
``` |
|
|
<class_id> <x_center> <y_center> <width> <height> |
|
|
``` |
|
|
All coordinates are normalized to [0, 1]. |
