Usage

Installation

pip install ultralytics

Python Inference

python

from ultralytics import YOLO
import cv2

# Load the model
model = YOLO('best.pt')

# Run inference
results = model('path/to/image.jpg')

# Process results
for result in results:
    boxes = result.boxes
    for box in boxes:
        # Get coordinates and confidence
        x1, y1, x2, y2 = box.xyxy[0].cpu().numpy()
        confidence = box.conf[0].cpu().numpy()
        
        print(f"Beetle detected with confidence: {confidence:.2f}")
        print(f"Bounding box: ({x1}, {y1}, {x2}, {y2})")

Command Line

yolo predict model=best.pt source='path/to/image.jpg'
