这是我的代码

import nltk
freq_dist = nltk.FreqDist(words)
print freq_dist.keys()[:50] # 50 most frequent tokens
print freq_dist.keys()[-50:] # 50 least frequent tokens

我收到此错误消息：

当你可能只需要一小部分时，你试图导入整个nltk。尝试编辑代码

from nltk import FreqDist
freq_dist = FreqDist(words)
print freq_dist.keys()[:50] # 50 most frequent tokens
print freq_dist.keys()[-50:] # 50 least frequent tokens
