在Android上序列化训练有素的模型

Question

我在Android上序列化经过训练的多层感知器模型时遇到问题。我正在使用WekaSTRIPPED.jar（WEKA-for-Android）

我的代码是：

Classifier cModel = new MultilayerPerceptron(); 
        try {
            cModel.buildClassifier(trainFile);
            weka.core.SerializationHelper.write(Directory + "/FourFModels/MLP.model", cModel);
            Log.e("MLP model", "created");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 

我得到的错误：
