Runtime vs compile time library configuration

Currently the set of libraries used for AVX2, AVX512, GPU, etc must be defined at compile time. This requires us to have separate builds for each runtime environments. Is there a way or perhaps any work on making this a runtime configurable setting?

@dawood actually no, because it involves pre compiled c++ binaries. You would make the binary sizes bigger by having different versions of it.

@saudet could chip in here but what you’re asking for is just now how code works.
No compiled code is that dynamic.

Yes, it’s possible to use cpu_features for this: https://github.com/eclipse/deeplearning4j/issues/7834#issuecomment-498170278
