【问题描述】：
我正在使用 CoreNLP 包对用户 cmets 做一些注释，由于我已经升级到 3.5.0 版本，我似乎反复遇到同样的错误：
从 edu/stanford/nlp/models/ner/english.all.3class.distim.crf.ser.gz 加载分类器 ...
从 /u/nlp/data/pos_tags_are_useless/egw4-reut.512.clusters 加载 distsim 词典 ...
java.lang.RuntimeException: java.io.FileNotFoundException: \u\nlp\data\pos_tags_are_useless\egw4-reut.512.clusters（系统找不到指定的路径） 在 edu.stanford.nlp.objectbank.ReaderIteratorFactory$ReaderIterator.setNextObject(ReaderIteratorFactory.java:225) （提示五十行错误）
这里的一些搜索让我得到了这些类似的问题：
Stanford NER Error: Loading distsim lexicon Failed 和 Stanford NER tagger generates 'file not found' exception with provided models 没有解决我的问题：我只使用 3.5.0 的代码和模型（通过 Maven Central）。我尝试从 NER 模型修改 props 文件并指向用户目录中的另一个 .clusters 文件，但没有成功（完全相同的错误）。
我用来实例化 CoreNLP 对象的代码也很标准，但这里是：
Properties props = new Properties();
props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
stan = new StanfordCoreNLP(props);
现在我在想我缺少一些明显的东西。任何帮助将不胜感激。
更完整的堆栈跟踪（如果有帮助的话）如下：

您能否包含运行的完整输出，或复制问题的最小示例？这个词典应该已经加载了模型（错误是它试图从我们的文件系统重新加载它），这让我相信模型已经损坏，或者之前出现了问题。要检查的另一件事是确保您的模型版本与您的 CoreNLP 版本相同。

谢谢，感谢您的评论，我找到了问题。斯坦福图书馆在一个实用程序类中用于处理其输出。模型和代码在使用它们的项目中都是 3.5.0，但事实证明问题出在 Maven 上，它在使用该实用程序类的项目中混合了传递依赖项并从 3.4 导入文件，导致混乱和随后的错误。
