On the JVM, we're trying to do something like pytorch/numpy on the JVM. We also have python bindings:

https://github.com/deeplearning4j/jumpy
We've been building this since 2014. Of note is we'll also be able to import TF, pytorch,.. in the next few months.
We're also an eclipse foundation project as of recently.
