我正在使用Deeplearning4j的Doc2Vec算法,当我在Windows 10 PC上运行它时工作正常,但是当我尝试在Linux机器上运行时,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:?]
我在几台Linux机器上试过这个,这两台机器都运行Xubuntu并具有sudo权限
以下是创建ParagraphVectors的代码: InputStream = 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):

答案 0 :(得分:1)
首先要坚持使用最新版本。你能发布完整的堆栈跟踪吗?这肯定是不是的根本原因。也许尝试使用nd4j-native-platform代替?通常这是缺少原生工件的问题。
