model = YOLO(“yolov8n.pt”)

metrics=model.val(data=’data.yaml’, split=’test’)

how to access the class loss or box loss from the variable metrics ? (urgently needed )?

I can only access this variables but I need wither box or cls loss ?

how to get it

`# Validate the model

metrics = model.val()  # no arguments needed, dataset and 

settings remembered

metrics.box.map    # map50-95 

metrics.box.map50  # map50

metrics.box.map75  # map75

metrics.box.maps   # a list contains map50-95 of each category`
