Print loss after every epoch in YOLOv8

Question

# Build a YOLOv9c model from scratch
model = YOLO('yolov8n.yaml')

# Build a YOLOv9c model from pretrained weight
model = YOLO('yolov8n.pt')

# Display model information (optional)
model.info()

results=model.train(data='data.yaml', epochs=1, imgsz=640, lr0=0.01, batch=32, device=[0, 1], optimizer='SGD', val=False, plots=False)

How to print training class loss after this code? If I write: print(results), the output is none.

But I want to see all the results such mAP, class loss, and others.
