--------------------------------------------------------------

Just of note if you use, deeplearning4j-nn, and the nd4j apis you don't 
actually need

deeplearning4j-core. Behind the scenes we've been working on modularizing core 
out quite a bit.

We may be able to help you here. What components of dl4j are you using?
 From the looks of it, it's just the configuration and some of the basic nd4j 
apis.

You can get away without using core. That should simplify things quite a bit.

 

Edit: Just checked the PR, it's already setup, so guava shouldn't be in there 
(it's only used in core) - but it indeed does seem to be a transitive 
dependency. Thanks for flagging this, let me see what we can do to minimize 
this on our side. It's being brought in by reflections, which we were planning 
on getting rid of anyways. We'll see what we can do to prioritize this and are 
also open to PRs there as well.
