Subject Re: Third-party package tests for MXNet nightly builds
Date Mon, 11 Feb 2019 14:59:24 GMT
Can't speak for the CI team, but in general I think that it is good idea.

On a separate note, I've been playing around with Sockeye recently and it's
great! Awesome work and glad to see MXNet used for such cutting edge use
I'd love to see closer collaboration with the Sockeye team and MXNet for
innovation, cross pollination, and evangelization of what MXNet can do .
