文件“/home/july/PythonProjects/test/tokenize.py”，第 3 行，在
从 nltk.tokenize 导入 regexp_tokenize、wordpunct_tokenize、blankline_tokenize

Python 正在寻找另一个具有相同名称的脚本。 Python 对包中的脚本和您自己的脚本感到困惑，因为它从您所在的文件夹开始搜索。
所以只需将您自己的脚本更改为另一个名称。

我重新启动终端后它可以工作。 我不知道为什么。

我弄错了，抱歉。
如果有人在 ide 中使用from nltk.tokenize import sent_tokenize出现错误，您可以尝试在控制台中运行它。

我的脚本名称也是 tokenize.py 并且运行时出错。 多谢，伙计

救了我的命，在刚刚更改了我的 python 脚本文件名之后
