我正在开发一个项目,要求我使用nltk和python标记标记.所以我想用这个.但想出了一些问题.我经历了很多其他已经问过的问题和其他论坛,但我仍然无法解决这个问题.问题是当我尝试执行以下操作时:

from nltk.tag import StanfordPOSTagger st = StanfordPOSTagger('english-bidirectional-distsim.tagger')

我得到以下内容:

    Traceback (most recent call last):

    `File "<pyshell#13>", line 1, in <module>

        raise LookupError('\n\n%s\n%s\n%s' % (div, msg, div))`
