无法在 Linux 中构建 ParagraphVectors

Question

我将 Doc2Vec 算法与 Deeplearning4j 一起使用，当我在我的 Windows 10 PC 上运行它工作正常，但是当我尝试运行它在 Linux 框，我收到以下错误：

java.lang.NoClassDefFoundError: Could not initialize class org.nd4j.linalg.factory.Nd4j
at org.deeplearning4j.models.embeddings.inmemory.InMemoryLookupTable$Builder.<init>(InMemoryLookupTable.java:581) ~[run.jar:?]
at org.deeplearning4j.models.sequencevectors.SequenceVectors$Builder.presetTables(SequenceVectors.java:801) ~[run.jar:?]
at org.deeplearning4j.models.paragraphvectors.ParagraphVectors$Builder.build(ParagraphVectors.java:663) ~[run.jar:?]

我已经在几台 Linux 机器上试过了，它们都是运行ning Xubuntu 并且有 sudo 权限

这是创建我的 ParagraphVectors 的代码： InputStream is = new ByteArrayInputStream(baos.toByteArray());

  LabelAwareSentenceIterator iter;
  iter = new LabelAwareListSentenceIterator(is, DELIM);
  iter.setPreProcessor(new SentencePreProcessor() {
    @Override
    public String preProcess(String sentence) {
      return new InputHomogenization(sentence).transform();
    }
  });

  TokenizerFactory tokenizerFactory = new DefaultTokenizerFactory();
  vec = new ParagraphVectors.Builder().minWordFrequency(minWordFrequency).batchSize(batchSize)
      .iterations(iterations).layerSize(layerSize).stopWords(stopWords).windowSize(windowSize)
      .learningRate(learningRate).tokenizerFactory(tokenizerFactory).iterate(iter).build();
  vec.fit();

这是我的 pom.xml（版本都是 0.7.1，但我一直在使用 0.4-rc3.9 并得到同样的错误）：

Answer 1

始终首先坚持使用最新版本。你能 post 完整的堆栈跟踪吗？这绝对不是根本原因。也许尝试使用 nd4j-native-platform 代替？通常这是缺少原生工件的问题。
