Question

from nltk.tag.perceptron import PerceptronTagger

tagger = PerceptronTagger()

def pos_tagging(X):
    tagset = None
    tokens = nltk.word_tokenize(X)
    tags = nltk.tag._pos_tag(tokens, tagset, tagger)
    pos_X = map(get_wordnet_pos, tags)
    return pos_X

将nltk版本更改为3.1并删除nltk.download()中之前的avareage perceptron tagger并重新安装
