A question about max_per_img in config

[NicholasIrving]

According to the explanation of max_num (int): if there are more than max_num bboxes after NMS, only top max_num will be kept. But if I want to keep all bboxes after NMS, what should I do?

You can set max_per_img as large as possible (e.g., equals to nms_pre).
