    Downloading package punkt to /home/aistudio/nltk_data...
      Unzipping tokenizers/punkt.zip.

解决方式二：手动下载移至对应目录

按照第一种方式如果出错会得到提示：

 Searched in:
    - '/root/nltk_data'
    - '/usr/nltk_data'
    - '/usr/share/nltk_data'
    - '/usr/lib/nltk_data'
    - '/usr/share/nltk_data'
    - '/usr/local/share/nltk_data'
    - '/usr/lib/nltk_data'
    - '/usr/local/lib/nltk_data'

下载punkt.zip包，解压缩后放置到/nltk_data/tokenizers文件目录下，然后将整个文件目录放置到其searched in的任意一个目录下就ok。
