安装后 NLTK 在 python 上不工作

Question

我安装了 NLTK、numpy 和 matplotlib，但每当我在导入 NLTK 后尝试运行任何代码时，都会出现一个错误，提示 nltk 不是一个包。当我导入 nltk 时它没有给我任何错误，这一切都发生在尝试导入文本或语料库之后。

我已经下载了库 注意我也试过 python shell，还是不行

import nltk from nltk.book import text1 Traceback (most recent call last): File "<pyshell#4>", line 1, in from nltk.book import text1 ModuleNotFoundError: No module named 'nltk.book'; 'nltk' is not a package

Answer 1

nltk图书馆默认不带尸体。您必须在导入 nltk 后下载这些才能访问 nltk.book

尝试以下 -

import nltk
nltk.download()

这会提示你下载相关的包内容，其中之一就是你要找的nltk.book-
