Question

我已经下载了Stanford corenlp Python包装器。我已经完成了link下的安装。

当我运行此代码时

>>> from stanford_corenlp_pywrapper import CoreNLP
>>> proc = CoreNLP("pos", corenlp_jars=["/home/sw/corenlp/stanford-corenlp-full-2015-04-20/*"])

我已经更改了jar位置，如下所示：

proc = CoreNLP("pos", corenlp_jars=["/media/pglab1-uni2/1EF20A75F20A5207/Anaconda2/stanford_corenlp_pywrapper-master/*"])

但是我收到如下错误：

INFO:CoreNLP_PyWrapper:mode given as 'pos' so setting annotators: tokenize, ssplit, pos, lemma

请帮我解决错误

Answer 1

两个原因可以是：

您没有包含被叫类或
你的罐子已损坏。

<强> 1。你没有jar 添加这些maven依赖项以获取与Standford CoreNLP相关的所有jar。

 <properties>
    <stanford.corenlp.version>3.9.1</stanford.corenlp.version>
 </properties>

  <dependencies>

       <dependency> 
           <groupId>edu.stanford.nlp</groupId>
           <artifactId>stanford-corenlp</artifactId>
           <version>${stanford.corenlp.version}</version>
       </dependency> 
       <dependency> 
           <groupId>edu.stanford.nlp</groupId>
           <artifactId>stanford-corenlp</artifactId>
           <version>${stanford.corenlp.version}</version>
           <classifier>models</classifier> 
        </dependency>
  </dependencies>

<强> 2。你的罐子已损坏

只需转到.m2文件夹并删除所有的Standford NLP罐子。再次从中央仓库下载jar。

3。如果你没有使用maven，那么检查你的jar是否已添加到classpath中？
