win10下使用nltk的brown的词性tag包报错以及处理方法安装nltk相应包的操作办法

笔者近期练习NLP的给句子的词性进行tag操作，操作中出错，具体显示如下：

以上错误的原因就是nltk的语言等等tag包没准备好，所以需要对nltk进行补齐安装：
操作如下（博主的环境是python3.6，使用anaconda下的jupyter notebook界面做python开发）

在jupyter notebook中的cell中输入：

import nltk
nltk.download()

输入后点击运行该cell，也可以使用shift+回车 组合键执行cell

然后cell下方会弹出一句话：

showing info https://raw.githubusercontent.com/nltk/nltk_data/gh-pages/index.xml

并且，系统会开启一个界面：



以博主的尿性，必然是选择界面中的 all 这一行，再点击“download”，就静待整个过程的完结了。
