Dear @clcarwin, If one wants to change the aspect ratio of anchor boxes, must _just_ changed the **detect** method in [`test.py`](https://github.com/clcarwin/SFD_pytorch/blob/master/test.py)? For example, line https://github.com/clcarwin/SFD_pytorch/blob/96fdfbe22eef176a04802d915834b82a131a854d/test.py#L39 or other methods moreover must changed?
