Where is the function MultiBoxPrior defined?


I was going through the SDD tutorial in the Gluon Straight Dope series and they have an import statement:

from mxnet.contrib.ndarray import MultiBoxPrior

and after searching the repo I can not find this function (besides the compiled multi_box files)

so is this defined in python anywhere?


It is auto-generated. see https://github.com/apache/incubator-mxnet/blob/master/python/mxnet/ndarray/register.py
The op impl is in operator/contrib/multibox_prior-*


Since you seem to be familiar with this, could you maybe paste the results of the auto-generated code?


It is a caller into C++ backend, something like MXFuncInvoke('MultiBoxPrior', ...)
