java - 使用开源版本的CoreNLP时无法加载OpenIE模型

Question

我从this page下载了coreNLP的源码以及 README 文件中推荐的型号。我在 Eclipse 中创建一个新项目并尝试运行 openie，它返回以下异常:

我已完成以下步骤:

1. 从 GitHub 克隆存储库:https://github.com/stanfordnlp/CoreNLP.git

2. 下载最新的模型 jar:http://nlp.stanford.edu/software/stanford-corenlp-models-current.jar

3. cd CoreNLP ; Ant

4. 此时您应该已经在 GitHub 上构建了最新版本的代码

5. 设置 CLASSPATH 以包含 CoreNLP/classes、CoreNLP/lib 和最新模型 jar

6. 运行此命令:java -Xmx4g edu.stanford.naturalli.OpenIE

它运行良好，所以我认为我们当前分发的内容没有任何问题。
