URL: https://github.com/apache/incubator-mxnet/issues/8156#issuecomment-381410705 I don't think the above repo has the functionality requested. May be you can tell which file does that. The caffe equivalent of the operator requested is https://github.com/zhaoweicai/cascade-rcnn/blob/master/src/caffe/layers/proposal_target_layer.cu. Something close which I found is https://github.com/apache/incubator-mxnet/blob/master/src/operator/contrib/multi_proposal-inl.h but doesn't perform label assignment or generate bbox weights and targets using gt boxes. I can possibly write this for mxnet and do a PR as I am interested in an efficient implementation. This is an automated message from the Apache Git Service.

URL: https://github.com/apache/incubator-mxnet/issues/8156#issuecomment-381365366 For end to end training, its not possible to prefetch. The position of the anchor-boxes changes based on the bounding box offsets in RPN and the assignment is done after the anchors are refined. The refined anchors (which are called proposals) are then compared with ground truth boxes, and label assignment is done (which is what proposal target layer does). I don't see how it can be done in pre-fetching This is an automated message from the Apache Git Service.
