Re: mxnet ndarray inference in js

[TongKe Xue]

Hi Hagay,

  Good point. The high level problem is:

  I want to run mxnet training on GPU, and inference on CPU --
browsers / javascript in particular.

  On the training side, I'm dealing mostly with NDArray / doing my own
gradient calculations / optimization. I would like some library for
the client side, where I can just 'port over my mxnet ndarray graph'
and start running inference.

  I hope this motivates the issue.

Hi,

  I'm looking for a js library compatible with mxnet/ndarray.

1. I am aware of https://github.com/dmlc/mxnet.js/
However:
a. that appears to be all of mxnet, not ndarray
b. that appears to only support Python models, whereas I'm using Java/Scala

2. I am aware of https://github.com/scijs/ndarray
However:
this appears to be in different library, try to create a unifying API over 
both

  Back to my original question -- is there some JS API that is
directly compatible with mxnet's ndarray interface?

Thanks,

[TongKe Xue]

If I'm understanding mxnet.js correctly, any mxnet model can be
converted to mxnet.js via:

https://github.com/dmlc/mxnet.js/blob/master/tools/model2json.py

and then executed on mxnet.js


Questions: is this 'mxnet json model' format documented anywhere?
