NameError: name 'sent_tokenize' is not defined

Question

我目前正在使用 google colab 读取 txt 文件并使用 nltk 将其分解成句子。

import nltk
nltk.download('punkt')
with open ('demo.txt','r') as file:
  content = file.read()
  print(content)
sentences = tokenize.sent_tokenize(content)
print(sentences)

当我点击运行,

[nltk_data] 正在将包 punkt 下载到 /root/nltk_data... [nltk_data]包 punkt 已经是最新的！ -------------------------------------------- ------------------------------ NameError Traceback（最后一次调用）在（） 1 导入 nltk 2 nltk.download('punkt') ----> 3 分词器= sent_tokenize() 4 句 = tokenize.sent_tokenize(内容) 5 打印（句子） NameError: 名称 'sent_tokenize' 未定义

出现这个错误。对了，我已经安装了nltk.
