About detach of proposal_bboxes #24

Hi, potterhsu,

Thank you very much for your code, I run it well but I have a question here about the detach of proposal boxes, why it should be detached, does it mean in total loss items there are always some items invalid for the two parts of network split by proposal_boxes when updating parameters each step?
