    Traceback (most recent call last):
    
    File
    <pyshell#155>, line 3, in <module>
    print nltk.sem.show_raw_rtuple(rel,Icon=True,rcon=True)
    AttributeError:
    module object has no attribute show_raw_rtuple


    在7.6关系抽取中,有如许一段代码



    >>>IN = re.compile(r.\bin\b(?!\b.+ing)
    >>>for docin nltk.corpus.ieer.parsed_docs(NYT_19980315):
    ...
    for rel in nltk.sem.extract_rels(ORGLOC, doc,
    ... corpus
    =ieer,pattern = IN):
    ...
    print nltk.sem.show_raw_rtuple(rel)

    此中有一句是


    nltk.sem.show_raw_rtuple(rel),然则运行呈现了错误,提示没有此办法。
    经过查询NLTK.sem的文档,发明这些函数都在更深的处所。也就是
    nltk.sem.relextract中。
