My NN implementation runs without normalization, but when I apply the NormalizerStandardize as follows I get the error  
java.lang.RuntimeException: Unsupported data rank  
I can’t figure out where this error is thrown, any help much appreciated

NormalizerStandardize normalizer = new NormalizerStandardize();  
DataSet dataSet = new DataSet(features,labels,null,null);  
normalizer.fit(dataSet);  
normalizer.transform(dataSet);
