Keras plot_model input and output shape only question mark

I'm trying to code YOLOV1 in Keras, and I use the VGG16 which accepts (224,224,3) while the input is (448, 448, 3) (that's the size used by the authors) so I added a Conv2D and a MaxPooling layer to convert 448 to 224. However, when I use plot_model…
