To download a particular dataset/models, use the nltk.download()function, e.g. if you are looking to download the punktsentence tokenizer, use:

$ python

From command line, after importing nltk, try
从命令行，导入 nltk 后，尝试
nltk.download('popular', halt_on_error=False)
After an error it will ask to retry broken package, just decline with n and it will continue with proper packages.
出现错误后，它会要求重试损坏的包，只需用 n 拒绝，它将继续使用正确的包。

a) in OSX either run
a) 在 OSX 中要么运行
sudo /Applications/Python\ 3.6/Install\ Certificates.command
sudo /Applications/Python\ 3.6/Install\ Certificates.command
b) switch to admin user (the one you have set up with administrator privileges)
b) 切换到 admin 用户（您设置的具有管理员权限的用户）
and type at command line:
并在命令行输入：
/Applications/Python\ 3.6/Install\ Certificates.command
/Applications/Python\ 3.6/Install\ Certificates.command
Notes:
笔记：
- "\" are necessary because they escape blank characters in file names.
- This procedure worked if you have python 3.6 installed, otherwise change it in order to match your install python version... for this execute:
- "\" 是必需的，因为它们会转义文件名中的空白字符。
- 如果您安装了 python 3.6，则此过程有效，否则请更改它以匹配您安装的 python 版本......为此执行：
ls /Applications
ls /Applications
and look at the python directory name you have there.
并查看您在那里的 python 目录名称。
