>                 Key: MXNET-40
>                 URL: https://issues.apache.org/jira/browse/MXNET-40
>             Project: Apache MXNet
>          Issue Type: Improvement
>            Reporter: Kan Wu
>            Assignee: Chris Olivier
>            Priority: Major
> The multi_proposal operator ({{mxnet.sym.contrib.MultiProposal}}, CPU 
> version) is not implemented before.
> I wrote the code about it.
> And I found there was a bug in _proposal.cu_ and _multi_proposal.cu_.
> The {{batch_size}} of the output of _Proposal_ and _MultiProposal_ are both 
> {{param_.rpn_post_nms_top_n}}.
> When {{count_anchors < param_.rpn_post_nms_top_n}}, the variable 
> {{rpn_post_nms_top_n}} will be {{count_anchors}}, which is less than 
> {{param_.rpn_post_nms_top_n}}.
> [https://github.com/apache/incubator-mxnet/blob/master/src/operator/contrib/proposal.cu#L438]
> It will cause the problem that the output whose index is larger than 
> {{rpn_post_nms_top_n}} will be _not assigned_.
