Usage

import torch
from models.experimental import attempt_load

# Load model
model = attempt_load('weights/best.pt', map_location='cuda')

# Inference
img = torch.randn(1, 3, 320, 320).cuda()
pred = model(img)

Per-class AP Access

import torch

# Load checkpoint with per-class AP
ckpt = torch.load('weights/epoch_499.pt', weights_only=False)

# Access per-class AP
per_class_ap = ckpt.get('per_class_ap', {})
for class_id, ap_data in per_class_ap.items():
    print(f"{ap_data['name']}: mAP@.5={ap_data['ap50']:.3f}, mAP@.7={ap_data['ap70']:.3f}")
