title: What should be the size of input image for training a YOLOv3 Model Architecture CNN.?
body: <p>I've implemented a YOLOv3 from scratch and I plan to fine-tune using MS-COCO weights for some different data.
  The dataset I've chosen has images of 720*1280 size.</p>
  <p>When I go through the YOLOv3 paper, 1st CONV2d layer is there with filter_size =3 and stride = 1, and output size is 256*256....</p>
  <p>Can someone give me a walkthrough for how YOLO training part works in here?</p>
