我在Deeplearning4j中使用了Doc2Vec算法,在我的Windows 10 PC上運行它時它工作正常,但是當我嘗試在Linux機器上運行它時,出現以下錯誤:無法在Linux中構建ParagraphVectors

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:?] 

我一對夫婦的Linux機器,而這兩者都是運行Xubuntu上的嘗試這樣做,有須藤權限

這裏是我創造的ParagraphVectors代碼: InputStream的是=新ByteArrayInputStream的( 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(); 

這裏是我的pom.xml(版本0.7.1所有,但我一直在使用0.4 rc3.9,並得到了同樣的錯誤):

始終堅持首先是最新版本。你能發佈完整的堆棧跟蹤嗎?這絕對是不是的根本原因。也許嘗試使用nd4j-native-platform代替?通常這是一個缺少原生文物的問題。

謝謝,我使用了nd4j-native-platform,現在它運行在Linux上。奇怪的是,我將它作爲Apache Storm集羣的一部分使用,並且我仍然遇到同樣的錯誤,但它在LocalCluster上與本地平臺一起工作,所以現在是Storm問題。 –
