训练OPenNLP错误

我正在尝试使用OpenNLP训练一个Name实体模型,但是得到这个错误不知道缺少什么.我是这个OPENNLP的新手,任何人请帮助,如果需要可以提供Train.txt文件

lineStream = opennlp.tools.util.PlainTextByLineStream@b52598

我的代码是这样的

    File fileTrainer=new File("/home/ashfaq/Documents/Train.txt");
    File output=new File("/home/ashfaq/Documents/trainedModel.bin");
    ObjectStream lineStream = new PlainTextByLineStream(new    FileInputStream(fileTrainer), "UTF-8");
    ObjectStream sampleStream = new NameSampleDataStream(lineStream);
    System.out.println("lineStream = " + lineStream);
    TokenNameFinderModel model = NameFinderME.train("en", "location", sampleStream, Collections.emptyMap(), 1, 0);

    BufferedOutputStream modelOut = null;
    try {
        modelOut = new BufferedOutputStream(new FileOutputStream(output));
        model.serialize(modelOut);
    } finally {
        if (modelOut != null)
            modelOut.close();
    }

这通常是由于训练数据中的标签后没有空格.例如,

bob 
will fail but 
 bob  
will succeed.

如果这不能解决问题,请发布一大块训练数据.另外,确保训练文件中的每个句子都在一行上.换句话说,所有句子都不应包含\n,并且必须以\n结尾
