How to build new operators?

[shdyn]

Hi, I need to compile the operators in https://github.com/deepinsight/insightface/tree/master/3rdparty/operator. I tried to copy files in that folder to incubator-mxnet/src/operator and compile the source codes using incubator-mxnet/docs/install/install_mxnet_ubuntu_python.sh. Then I install these operators using incubator-mxnet/python/setup.py. However, I still cannot run these operators? Any suggestions. Thanks in advance!

Did you receive any kind of error when you tried to compile mxnet? Also, the new operator FAQ might be able to help you https://mxnet.incubator.apache.org/versions/master/faq/new_op.html?

Thanks for your reply. There was no error in compiling. I also refered https://github.com/reminisce/mxnet/blob/900a6997ded8f7124fc6323aa66408cb70e8253f/docs/how_to/add_op_in_backend.md

With today's new updated website launch - https://mxnet.incubator.apache.org/api/faq/new_op should be the link @zachgk

@shdyn
I copy pasted the files into src/operator/. directory. Rebuilt it.
Tried the following

>>> import mxnet as mx
>>> mx.nd.AmSoftmax(data=mx.nd.arange(0,12).reshape(3,4),weight=mx.nd.arange(0,4).reshape(1,4),label=mx.nd.array([0,0,1]),num_hidden=1)

[[14.]
 [38.]
 [62.]]
<NDArray 3x1 @cpu(0)>

This didn't give me any error

For more details about using the function, help() might be helpful

>>> help(mx.nd.AmSoftmax)

Let me know if it helps.

@zachgk Is this good to close since I think we've answered this question and the author hasn't responded for a while.
