Question

Почему я получаю ошибку

java.lang.NoClassDefFoundError: org/nd4j/linalg/api/ops/impl/transforms/floating/Histogram

при попытке настроить прослушиватель как gan.setListeners(new StatsListener(statsStorage)); для такой сети

GAN (из примера кода https://github.com/wmeddie/dl4j-gans):

generator = generatorSupplier.get();
        generator.init();

        Layer[] genLayers = generator.getLayers();
        int numGenLayers = genLayers.length;

        discriminator = discriminatorSupplier.provide(updater);
        discriminator.init();

        MultiLayerNetwork ganDiscriminator = discriminatorSupplier.provide(UPDATER_ZERO);
        ganDiscriminator.init();

        Layer[] disLayers = ganDiscriminator.getLayers();
        Layer[] layers = ArrayUtils.addAll(genLayers, disLayers);
        MultiLayerConfiguration genConf = generator.getLayerWiseConfigurations();
        MultiLayerConfiguration disConf = ganDiscriminator.getLayerWiseConfigurations();
        org.deeplearning4j.nn.conf.layers.Layer[] confLayers = new org.deeplearning4j.nn.conf.layers.Layer[layers.length];

        Map<Integer, InputPreProcessor> preProcessors = new HashMap<>();
        for (int i = 0; i < layers.length; i++) {
            confLayers[i] = layers[i].conf().getLayer();
            if (i < numGenLayers) {
                preProcessors.put(i, genConf.getInputPreProcess(i));
            } else {
                preProcessors.put(i, disConf.getInputPreProcess(i - numGenLayers));
            }
        }

        MultiLayerConfiguration ganConf = new NeuralNetConfiguration.Builder()
                .seed(seed)
                .updater(updater)
                .biasUpdater(biasUpdater)
                .optimizationAlgo(optimizer)
                .gradientNormalization(gradientNormalizer)
                .gradientNormalizationThreshold(gradientNormalizationThreshold)
                .activation(Activation.IDENTITY)
                .trainingWorkspaceMode(trainingWorkSpaceMode)
                .inferenceWorkspaceMode(inferenceWorkspaceMode)
                .cacheMode(cacheMode)
                .list(confLayers)
                .inputPreProcessors(preProcessors)
                .build();
        gan = new MultiLayerNetwork(ganConf);
        gan.init();

Так что же не так и как сделать так, чтобы панель инструментов localhost: 9000 работала для этого?

И когда я пытаюсь наблюдать, скажем, только генератор, Я получаю пустые панели на локальном хосте: 9000

Версия пользовательского интерфейса в pom. xml равна

в то время как другие зависимости были:

UPD. Переключение всех на бета3 сделало эту ошибку при попытке заставить UI слушать сеть gan:
