Usage with LibreYOLO

from libreyolo import LibreYOLO

# Load model (auto-downloads from HuggingFace if not found locally)
model = LibreYOLO("LibreYOLONASl.pt")

# Run inference
result = model("image.jpg", conf=0.25, iou=0.45)

# Process results
print(f"Found {len(result)} objects")
print(result.boxes.xyxy)   # bounding boxes (N, 4)
print(result.boxes.conf)   # confidence scores (N,)
print(result.boxes.cls)    # class IDs (N,)
