Question

我一直在尝试在我的代码中使用nltk.pos_tag，但是当我这样做时我遇到了错误。我已经下载了Penn treebank和max_ent_treebank_pos。但错误仍然存在。这是我的代码：

import nltk
from nltk import tag
from nltk import*



a = "Alan Shearer is the first player to score over a hundred Premier League goals."
a_sentences = nltk.sent_tokenize(a)
a_words     = [nltk.word_tokenize(sentence) for sentence in a_sentences]
a_pos       = [nltk.pos_tag(sentence) for sentence in a_words]
print(a_pos)

这是我得到的错误：

"Traceback (most recent call last):
  File "<pyshell#9>", line 1, in <module>
  print (nltk.pos_tag(text))
  File "C:\Python34\lib\site-packages\nltk\tag\__init__.py", line 110, in  pos_tag
tagger = PerceptronTagger()

Answer 1

从python中调用它：

nltk.download（＆＃39; averaged_perceptron_tagger＆＃39）

Answer 2

在Flask服务器中遇到同样的问题。 nltk在服务器配置中使用了不同的路径，因此我反复在nltk.data.path.append("/home/yourusername/whateverpath/")调用之前在服务器代码中添加pos_tag

请注意，此问题有一些复制

要解决此错误，请在 python 提示符下运行以下命令：

Stack(
  children: [
    Positioned(
      top: 10.0,
      left: 10.0,
      child: ListView(
         child: Container(
           height: 120.0,
           child: firstStack(),
         )
      ),
   ),
   Positioned(
      bottom: 0.0,
      right: 10.0
      ListView(
         child: Container(
           height: 120.0,
           child: firstStack(),
         )
      ),
   ),
  ]
),

使用nltk.post_tag时出错
