Hi @aaronmarkham , thanks for your effort. Given MKL-DNN backend is already GA in 1.3.0 release, if it is possible to promote how to build it from source, especially for CPU platform? Currently, I didn't find any content about that on the install from source webpage for either 1.2.1 or master.

Thanks @aaronmarkham !

@TaoLv I do not think MKL-DNN is GA in 1.3.0. I am aware of ongoing work on master to complete test coverage. Regardless, I think this is a good suggestion to add an explanation for that on the install web page. Would be great if you can contribute this!

@aaronmarkham code change looks good, but since this involves UI updates, would be great if you have a host that runs the code to share. Thanks!

[TaoLv]

Thanks for your clarification, @lupesko. I read the message about MKL-DNN GA from here: https://cwiki.apache.org/confluence/display/MXNET/Apache+MXNet+%28incubating%29+1.3.0+Release+Status
I think this decision was disscussed on dev@ and can reflect the status of MKL-DNN backend as well as those effort from the community.

Regarding the doc change, can you kindly point out which source file maps to the install web page?

[aaronmarkham]

@lupesko - I added preview links to the description. The one thing that isn't showing is the pip table. I could add a new image and change the links to point to that if we want to see the real preview of that too...

[lupesko]

Thanks @aaronmarkham - looks good.
I'm wondering if it may be desired to replace/refresh the "Introducing the Scala Inference API" box from 1.2 with something new released with MXNet 1.3.0? Options include Clojure API, ONNX export, TensorRT. WDYT?

[lupesko]

Code changes look good.
Also checked the host running the code: homepage and install page - both looks good.

[aaronmarkham]

@lupesko what if we point to the medium post and mention all three...

[Roshrini]

Is this PR ready to go now?

[aaronmarkham]

@Roshrini - yes, the latest preview is up with new news: http://34.201.8.176/versions/1.3.0_release/
