NameError：name'stopwords'is not defined

由於某種原因，我收到錯誤NameError: name 'stopwords' is not defined，即使我已經安裝了該軟件包。我試圖對一些反饋評論進行自然語言處理。 dataset對象是具有兩列的表格，Reviews (a sentence of feedback)和目標變量Liked (1 or 0)。謝謝，謝謝！NameError：name'stopwords'is not defined

你從nltk.corpus進口禁用詞有？ – Nabin

@Nabin哦哇，它的工作！非常感謝。我接下來的教程沒有，但它對他們有效，奇怪......再次感謝！ – james

你只需要在代碼中使用stopwords之前添加以下行：

from nltk.corpus import stopwords
