# Basic installation
pip install aegis-vision

# With Kaggle support
pip install aegis-vision[kaggle]

# Development installation

Quick Start

Training a YOLO Model

from aegis_vision import YOLOTrainer

# Initialize trainer
trainer = YOLOTrainer(
    model_variant="yolov11l",
    dataset_path="/kaggle/input/my-dataset",
    epochs=100,
    batch_size=16,
)

# Configure Wandb tracking (optional)
trainer.setup_wandb(
    project="my-project",
    entity="my-team",
    api_key="your-api-key"
)

# Train
results = trainer.train()

# Export to multiple formats
trainer.export(formats=["onnx", "coreml", "openvino"])

Converting COCO to YOLO Format

from aegis_vision import COCOConverter

# Convert dataset
converter = COCOConverter(
    annotations_file="annotations.json",
    images_dir="images/",
    output_dir="yolo_dataset/"
)

stats = converter.convert()
print(f"Converted {stats['total_annotations']} annotations")

Command-Line Interface
