What are the requirements for Deeplearning4j?  I followed the instructions
on the wiki (https://wiki.apache.org/tika/TikaAndVisionDL4J).

I have a JVM with Tika Server
and tika-dl-1.17-SNAPSHOT-jar-with-dependencies.jar.  When it runs I get
the following error:

tika_1  | # A fatal error has been detected by the Java Runtime Environment:
tika_1  | #
tika_1  | #  SIGSEGV (0xb) at pc=0x00007f184b4097d6, pid=1,

tika_1  | # Problematic frame:
tika_1  | # C  [libgomp.so.1+0x67d6]  omp_set_num_threads+0x26

The error comes from:
this.graph = KerasModelImport.importKerasModelAndWeights(modelJsonPath,
modelWeightsPath, false);

The core dump
mentions org.deeplearning4j.nn.modelimport.keras.Hdf5Archive.readDataSet,
org.nd4j.linalg.factory.Nd4j, org.nd4j.nativeblas.Nd4jCpu$NativeOps
Are there some more prerequisites other than the 2 jars?

Thanks.
