java.lang.ClassNotFoundException и java.lang.NoClassDefFoundError - Android и Deeplearning4j dl4j

Question

Я начал работать с deeplearning4j в Android, но у меня есть проблема, которая не имела решения в последние дни.

Когда я определяю нейронную сеть, я не вижу проблем, связанных с отсутствиемклассы или что-то подобное.

        DenseLayer inputLayer = new DenseLayer.Builder()
                .nIn(n_inputs)
                .nOut(45)
                .name("Input")
                .build();

        DenseLayer hiddenLayer = new DenseLayer.Builder()
                .nIn(45)
                .nOut(45)
                .name("Hidden")
                .build();

        OutputLayer outputLayer = new OutputLayer.Builder(LossFunctions.LossFunction.NEGATIVELOGLIKELIHOOD)
                .nIn(45)
                .nOut(n_outputs)
                .name("Output")
                .activation(Activation.SOFTMAX)
                .build();

        NeuralNetConfiguration.Builder nncBuilder = new NeuralNetConfiguration.Builder();

Однако, когда я запускаю свое приложение, я сталкиваюсь с ошибкой типа java.lang.NoClassDefFoundError и java.lang.RuntimeException. Класс распознается при разработке кода, но не после компиляции. Проблема находится в строке определения OutputLayer.
