Also the image original size is about 2000x1000.\r\nI tried to collect statistics about bounding box size and aspect ratio on my dataset, and apply those majority on the parameters. However, the trained model did not work very well even on the training set.\r\nCould you explain more about how you select the (min_size, max_size) and aspect_ratio on each layer? Thank you very much!
