DeepLearning4j的示例編譯錯誤

Question

使用DeepLearning4j編程時遇到一些問題。

當我在Eclipse中打開並編譯示例MnistMultiThreadedExample時，就會出現這些問題。

import org.deeplearning4j.datasets.iterator.impl.MnistDataSetIterator;
import org.deeplearning4j.datasets.test.TestDataSetIterator;
import org.deeplearning4j.iterativereduce.actor.multilayer.ActorNetworkRunner;**(error)**
import org.deeplearning4j.models.classifiers.dbn.DBN;**(error)**
import org.deeplearning4j.nn.conf.NeuralNetConfiguration;
import org.deeplearning4j.scaleout.conf.Conf;**(error)**

就是說這些軟件包不在目標軟件包中。 而且我無法在包中找到這些模塊，也無法在Maven Center存儲庫中找到它們，而我卻無法在源代碼中找到類。

現在，我想知道如何獲得這些模塊，以及在創建可以在Spark上運行的AutoEncoder之前應該做什么。

示例代碼如下所示：

import org.deeplearning4j.datasets.iterator.impl.MnistDataSetIterator;
import org.deeplearning4j.datasets.test.TestDataSetIterator;
import org.deeplearning4j.iterativereduce.actor.multilayer.ActorNetworkRunner;
import org.deeplearning4j.models.classifiers.dbn.DBN;
import org.deeplearning4j.nn.conf.NeuralNetConfiguration;
import org.deeplearning4j.scaleout.conf.Conf;

public class MnistMultiThreadedExample {
    public static void main(String[] args) throws Exception {
        //5 batches of 100: 20 each
        MnistDataSetIterator mnist = new MnistDataSetIterator(20, 60000);
        TestDataSetIterator iter = new TestDataSetIterator(mnist);
        ActorNetworkRunner runner = new ActorNetworkRunner(iter);


        NeuralNetConfiguration conf2 = new NeuralNetConfiguration.Builder()
            .nIn(784).nOut(10).build();

        Conf conf = new Conf();
        conf.setConf(conf2);
        conf.getConf().setFinetuneEpochs(1000);
        conf.setLayerSizes(new int[]{500,250,100});
        conf.setMultiLayerClazz(DBN.class);
        conf.getConf().setnOut(10);
        conf.getConf().setFinetuneLearningRate(0.0001f);
        conf.getConf().setnIn(784);
        conf.getConf().setL2(0.001f);
        conf.getConf().setMomentum(0.5f);
        conf.setSplit(10);
        conf.getConf().setUseRegularization(false);
        conf.setDeepLearningParams(new Object[]{1,0.0001,1000});
        runner.setup(conf);

        runner.train();

    }

}

Answer 1

您應該將以下依賴項添加到POM：

<dependency>
    <groupId>org.deeplearning4j</groupId>
    <artifactId>deeplearning4j-scaleout-akka</artifactId>
    <version>0.0.3.3</version>
</dependency>

這將作為傳遞依賴deeplearning4j-scaleout-api添加deeplearning4j-scaleout-api和deeplearning4j-core 。 這三個依賴項將為您提供您缺少的導入。
