                    import torch
                    from small_256_model import UNet as small_UNet
                    from big_1024_model import UNet as big_UNet
                    
                    # Load the model
                    checkpoint = torch.load('model_weights.pth')
                    model = big_UNet() if checkpoint['model_config']['big'] else small_UNet()
                    model.load_state_dict(checkpoint['model_state_dict'])
                    model.eval()
