AVX2 Configuration

Even though I have AVX2 configured in the POM.xml

…

<dl4j-master.version>1.0.0-beta7</dl4j-master.version>


<nd4j.backend>nd4j-native</nd4j.backend>

I still get the message:

o.n.l.c.n.CpuNDArrayFactory - *********************************** CPU Feature Check Warning ***********************************
o.n.l.c.n.CpuNDArrayFactory - Warning: Initializing ND4J with Generic x86 binary on a CPU with AVX/AVX2 support
o.n.l.c.n.CpuNDArrayFactory - Using ND4J with AVX/AVX2 will improve performance. See deeplearning4j.org/cpu for more details
o.n.l.c.n.CpuNDArrayFactory - Or set environment variable ND4J_IGNORE_AVX=true to suppress this warning
o.n.l.c.n.CpuNDArrayFactory - *************************************************************************************************

Any idea what is going wrong?

Ok, I found it. It’s deeplearning4j.masterversion and it need to go in the other dependencies section.
