word2vec deeplearning4j ArrayIndexOutOfBoundsException异常

Question

我培训了来自http://deeplearning4j.org/word2vec 的word2vec模型成功，现在在尝试应用 wordsNearest时，此异常：

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 99

这是我的代码：

package org.deeplearning4j.examples.nlp.word2vec; 
import java.io.File; 
import java.util.Collection; 
import org.deeplearning4j.models.embeddings.loader.WordVectorSerializer; 
import org.deeplearning4j.models.embeddings.wordvectors.WordVectors; 
public class NearestWords { 
    public static void main(String[] args) throws Exception{ 
     File file = new File("pathToWriteto.txt"); 
     WordVectors vec = WordVectorSerializer.loadTxtVectors(file); 
     Collection<String> similar = vec.wordsNearest("day", 10); 
     System.out.println(similar); 
    } 
}

当前版本（0.4-rc3.10）在loadTxt函数中有一个错误。它在主仓库中得到修复，并将在下一个版本中反映出来。阅读这个github问题你的问题： https://github.com/deeplearning4j/deeplearning4j/issues/1721

现在一个简单的修复方法是将最新的WordVectorSerializer.java复制到您的项目。 https://github.com/deeplearning4j/deeplearning4j/blob/master/deeplearning4j-scaleout/deeplearning4j-nlp/src/main/java/org/deeplearning4j/models/embeddings/loader/WordVectorSerializer.java
