elif字[0]。isdigit():
索引器错误:字符串索引超出范围
事实上word[0].isdigit():
抛出错误意味着word
是一个空字符串。最可能的原因是您的正则表达式拆分有时会产生空字符串
解决办法是,在
words = re.split(self.word_split_pattern, sentence)
排队
words = [w for w in words if len(w) > 0]
如果word[0].isdigit():
抛出该错误,word
有时是空字符串。要添加到我以前的注释中,回溯中有很多函数调用。如果在下游的某个地方输入了空单词(在您只是调用的代码中),那么调试可能会很困难。另一方面,可能修复方法很简单,只需将空字符串从re.split(self.word\u split\u模式,句子)
words=[w for w in words if len(w)>0]
中过滤出来,然后将其传递到nltk.pos\u标记()
。我只是在猜测,但尝试似乎没有什么坏处。这修复了错误,但使生成的句子没有空格。修复了问题。在words=[“::”.为nltk.pos\u标记(words)]中的标记添加了一些空格。
