NLTK单词标记化不'；我什么也不退

我试图标记一个句子，我相信代码是正确的，但没有输出。有什么问题吗？这是代码

import nltk
from nltk.tokenize import word_tokenize
text = word_tokenize("And now for something completely different")
nltk.pos_tag(text)

text = word_tokenize("They refuse to permit us to obtain the refuse permit")
nltk.pos_tag(text)

似乎缺少以下软件包

朋克

平均感知器

注意：您需要第一次下载它们

试试这个

import nltk

nltk.download('punkt')
nltk.download('averaged_perceptron_tagger')

from nltk.tokenize import word_tokenize
text = word_tokenize("And now for something completely different")
print(nltk.pos_tag(text))

text = word_tokenize("They refuse to permit us to obtain the refuse permit")
print(nltk.pos_tag(text))

print("----End of execution----")

看一看
