java - ValueError:找不到hazm库的stanford-postagger.jar文件-Python NLP

我想运行一个需要斯坦福postagger.jar的代码。但是我有这个错误:

  File "/usr/lib/python2.7/site-packages/nltk/internals.py", line 562, in find_jar
    (name, path_to_jar))
ValueError: Could not find stanford-postagger.jar jar file at resources/stanford-postagger.jar

我该如何解决此错误？

编辑:
我从hazm模块使用:

from hazm import POSTagger
tagger = POSTagger()
tagger.tag(word_tokenize('ما بسیار کتاب می‌خوانیم'))

完整结果:

Traceback (most recent call last):
  File "pyt.py", line 8, in <module>
    tagger = POSTagger()
  File "/home/vahid/dev/hazm/hazm/POSTagger.py", line 14, in __init__
    super(stanford.POSTagger, self).__init__(*args, **kwargs)
  File "/usr/lib/python2.7/site-packages/nltk/tag/stanford.py", line 42, in __init__
    verbose=verbose)
  File "/usr/lib/python2.7/site-packages/nltk/internals.py", line 562, in find_jar
    (name, path_to_jar))
ValueError: Could not find stanford-postagger.jar jar file at resources/stanford-postagger.jar

最佳答案

您首先需要斯坦福大学的postagger.jar文件，还需要训练自己的标记器。但hazm开发人员已将您需要的资源目录上传到此处:http://dl.dropboxusercontent.com/u/90405495/resources.zip

您将需要解压缩文件夹并将其保存到运行脚本的目录中。

例如:

$ mkdir testdir
$ wget https://github.com/sobhe/hazm/archive/master.zip
$ unzip master.zip -d testdir
$ cd testdir
$ mv hazm-master/hazm/ .
$ wget http://dl.dropboxusercontent.com/u/90405495/resources.zip
$ unzip resources.zip -d .
