手动从这歌网站下载zip
https://github.com/nltk/nltk_data/tree/gh-pages
如果解压缩失败，使用这个网站下载github的链接，注意是复制zip的链接
https://d.serctl.com
输入下面这条
https://d.serctl.com/?url=https://github.com/nltk/nltk_data/archive/refs/heads/gh-pages.zip
参考官方文档的要求，需要新建nltk_data文件夹，同时新建相应的文件夹https://www.nltk.org/data.html#
Manual installation
Create a folder nltk_data, e.g. C:\nltk_data, or /usr/local/share/nltk_data, and subfolders chunkers, grammars, misc, sentiment, taggers, corpora, help, models, stemmers, tokenizers.
Download individual packages from https://www.nltk.org/nltk_data/ (see the “download” links). Unzip them to the appropriate subfolder. For example, the Brown Corpus, found at:https://raw.githubusercontent.com/nltk/nltk_data/gh-pages/packages/corpora/brown.zip is to be unzipped to nltk_data/corpora/brown.
Set your NLTK_DATA environment variable to point to your top level nltk_data folder.
