Set the rationality of the partcls_loss

[zel-1]

First of all, thank you very much for your work.Secondly, I am a little confused about the partcls_loss.At the beginning of the training, the regions clipped from the original image may be the background area, but you gave it an original image label. Will it cause errors in the convergence direction of the network and the normal direction?Looking forward to your reply. Thank you!

我想请问ProposalNet指的是什么？ 论文中Navigator参考了PFN和Faster R-CNN 在代码中怎么体现的呢？
