我是python和nltk的新手.我已将代码从https://gist.github.com/alexbowe/879414转换为下面给出的代码,以使其运行许多文档/文本块.但是我得到了以下错误

 Traceback (most recent call last):
 File "E:/NLP/PythonProgrames/NPExtractor/AdvanceMain.py", line 16, in    <module>
  result = np_extractor.extract()
 File "E:\NLP\PythonProgrames\NPExtractor\NPExtractorAdvanced.py", line 67,   in extract
 for term in terms:
File "E:\NLP\PythonProgrames\NPExtractor\NPExtractorAdvanced.py", line 60, in get_terms
 for leaf in self.leaves(tree):
 TypeError: leaves() takes 1 positional argument but 2 were given

任何人都可以帮我解决这个问题.我必须从数百万的产品评论中提取名词短语.我使用Java使用Standford NLP工具包,但它非常慢,所以我认为在python中使用nltk会更好.如果有更好的解决方案,请同时推荐.

stopwords = stopwords.words('english')
