无法使用nltk运行python脚本

Question

我在本地主机上使用nltk运行python脚本。我的代码是：

#!C:\Users\fname lname\AppData\Local\Programs\Python\Python37-32\python.exe

print("Content-type: text/plain\n")
print("Single Quotes")
print("checkkk") 

from nltk.tokenize import sent_tokenize, word_tokenize

EXAMPLE_TEXT = "Hello Mr. Smith, how are you doing today? The weather is great, and Python is awesome. The sky is pinkish-blue. You shouldn't eat cardboard."

print(sent_tokenize(EXAMPLE_TEXT))

输出为：

Single Quotes
checkkk
Content-type: text/plain

Single Quotes
checkkk

问题是：在此行之后，不考虑nltk导入和代码。请帮忙。

Answer 1

检查是否为nltk.sent_tokenize()下载了必要的数据文件。
使用nltk.download('punkt')下载它们。
