斯坦福NER错误：加载distsim词典失败

Question

在我的项目中。我需要使用NER注释，所以我使用了NERDemo.java 当我创建一个新项目并且只有这个代码时，它工作正常，但当我将它添加到我的项目时，我不断收到错误。我已将代码中的路径编辑到分类器的特定位置。

我添加了Jar文件：

这是代码：

String serializedClassifier = "/Users/ha/stanford-ner-2014-10-26/classifiers/english.all.3class.distsim.crf.ser.gz";
    String serializedClassifier2 = "/Users/ha/stanford-ner-2014-10-26/classifiers/english.muc.7class.distsim.crf.ser.gz";

    if (args.length > 0) {
      serializedClassifier = args[0];
    }

    NERClassifierCombiner classifier = new NERClassifierCombiner(false, false, serializedClassifier, serializedClassifier2);

    String fileContents = IOUtils.slurpFile("/Users/ha/NetBeansProjects/StanfordPOSCode/src/stanfordposcode/input.txt");
    List<List<CoreLabel>> out = classifier.classify(fileContents);

    int i = 0;
    for (List<CoreLabel> lcl : out) {
      i++;
      int j = 0;
      for (CoreLabel cl : lcl) {
        j++;
        System.out.printf("%d:%d: %s%n", i, j,
                cl.toShorterString("Text", "CharacterOffsetBegin", "CharacterOffsetEnd", "NamedEntityTag"));
      }
    }

但我收到了这个错误：

您正在混合和匹配3.4版中的代码和3.5版中的模型。我建议将所有内容升级到最新版本。
