I’m trying to build `libnd4j` with `AVX512` support, from [GitHub - eclipse/deeplearning4j: Suite of tools for deploying and training deep learning models using the JVM. Highlights include model import for keras, tensorflow, and onnx/pytorch, a modular and tiny c++ library for running math code and a java based math library on top of the core c++ library. Also includes samediff: a pytorch/tensorflow like library for running deep learning using automatic differentiation.](https://github.com/eclipse/deeplearning4j.git) using the tag `deeplearning4j-1.0.0-beta7`.

I’ve tried different build environments, including Ubuntu 18.04 (GCC 8 and 9) and CentOS 7 (GCC 8). I’ve followed the instructions from [https://deeplearning4j.konduit.ai/getting-started/build-from-source](https://deeplearning4j.konduit.ai/getting-started/build-from-source).

The libraries produced do not include the same set of AVX512 instructions that I find on the `libnd4j` that has been published to Maven Central. Also, they don’t have the same performance as the published ones.  
I suspect my build environment, including dependencies and compiler versions may not be correct.

Are there any update resources regarding the `deeplearning4j` build from source or could you help me setup the correct environment and instructions to follow, please?

Thank you
