About model’s parameter

[EricPengShuai]

why do the model have this two parameter ？

pytorch-yolo-v3/detect.py

Line 177 in fbb4ef9

model(get_test_input(inp_dim, CUDA), CUDA)

In addition，why do the get_test_input function imread dog-cycle-car.png although for different test images？

def get_test_input(input_dim, CUDA):
    img = cv2.imread("dog-cycle-car.png")
    img = cv2.resize(img, (input_dim, input_dim)) 
    img_ =  img[:,:,::-1].transpose((2,0,1))
    img_ = img_[np.newaxis,:,:,:]/255.0
    img_ = torch.from_numpy(img_).float()
    img_ = Variable(img_)
    
    if CUDA:
        img_ = img_.cuda()
    num_classes
    return img_
