出于某种原因，我收到错误 NameError: name 'stopwords' is not defined，即使我已经安装了软件包。我正在尝试对一些反馈评论进行自然语言处理。 dataset 对象是一个包含两列的表，Reviews(反馈的一句话) 和目标变量 Liked(1 或 0)。帮助赞赏，谢谢!
block 1
import re
import nltk
nltk.download('stopwords')
输出 1

dataset['Review'][0]
review = re.sub('[^a-zA-Z]',' ' ,dataset['Review'][0])
review = review.lower()
review = review.split()
review = [word for word in review if not word in stopwords.words('english')] **ERROR ON THIS LINE**
输出 2

最佳答案
您只需在代码中使用stopwords 之前添加以下行:
from nltk.corpus import stopwords
