We should keep this argument name as overlap_threshold, since we don't need nms prefix. It can generate some inconsistency with current topi nms operator, but topi nms argument names will be modified in SSD refactor PR.

Thanks for pointing this out. I intentionally changed them to keep consistent to top. I will change them back.

This is needed because fcompute needs to receive an Array of Tensor when returning to c++. We can probably refactor the packfunc conversion a little bit to accept both Array and Tensor.

NNVM automatically wraps result in Array:

But Relay does not:
https://github.com/dmlc/tvm/blob/e5d92e1b96c1fbc175be741f522c030f2d91a613/src/relay/ir/op.cc#L129-L135
Relay doc asks for schedule function that returns list. So this is indeed complying with existing Relay interface.

This PR enables ssd test by attaching the
fcomputeandfscheduleimplementations in TOPI tomultibox_priorandnmsoperators.It also implements the customized
multibox_priorandmultibox_detectionops in mxnet.py to enable support of conversion from MxNet.tutorial/nnvm/deploy_ssd.pyis used to verify the above changes.@tqchen @kevinthesun @yzhliu
