You are currently trying to download every item in nltk data, so this can take long. You can try downloading only the stopwords that you need:
您当前正在尝试下载 nltk 数据中的每个项目，因此这可能需要很长时间。您可以尝试仅下载您需要的停用词：
import nltk
nltk.download('stopwords')
Or from command line (thanks to Rafael Valero's answer):
或者从命令行（感谢Rafael Valero 的回答）：
python -m nltk.downloader stopwords

您可以在控制台中单独执行此操作。

If your PC uses proxy for connectivity, then try this:
如果您的 PC 使用代理进行连接，请尝试以下操作：

nltk.download('stopwords')

Just run this command in your ipython notebook (or any other text editor/IDE you are using):
只需在您的 ipython 笔记本（或您正在使用的任何其他文本编辑器/IDE）中运行此命令：
import nltk
nltk.download('stopwords')
It will automatically download the stopwordfile and unzip it into the required directory.
它将自动下载stopword文件并将其解压缩到所需的目录中。

If you are running this command in a jupyter notebook, it opens another window titled 'NLTK Downloader'. Once you go in that window, you can select the topics you want to download and then click on download button to start downloading.
如果您在 jupyter notebook 中运行此命令，它会打开另一个标题为“NLTK Downloader”的窗口。进入该窗口后，您可以选择要下载的主题，然后单击下载按钮开始下载。
Until you close the NLTK Downloader window, the cell in the Jupyter keeps on running.
在您关闭 NLTK Downloader 窗口之前，Jupyter 中的单元会继续运行。
