如何从文本生成搭配

Question

我是NLP的新手，正在阅读一篇关于搭配的文章。下面是使用nltk从文本生成搭配的代码片段。在实现代码时，我得到了下面分享的错误。我不能明白我做错了什么。我还参考了官方文档nltk/collocation，方法是不同的，我在遵循它时遇到了困难。

from nltk.corpus import genesis
tokens = genesis.words('english-kjv.txt')
gen_text = nltk.Text(tokens)
gen_text.collocations()

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-115-a1efe81f5efd> in <module>
      3 tokens = genesis.words('english-kjv.txt')
      4 gen_text = nltk.Text(tokens)
----> 5 gen_text.collocations()

~\anaconda3\lib\site-packages\nltk\text.py in collocations(self, num, window_size)
    442 
    443         collocation_strings = [
--> 444             w1 + " " + w2 for w1, w2 in self.collocation_list(num, window_size)
    445         ]
    446         print(tokenwrap(collocation_strings, separator="; "))

~\anaconda3\lib\site-packages\nltk\text.py in <listcomp>(.0)
    442 
    443         collocation_strings = [
--> 444             w1 + " " + w2 for w1, w2 in self.collocation_list(num, window_size)
    445         ]
    446         print(tokenwrap(collocation_strings, separator="; "))

ValueError: too many values to unpack (expected 2)

请参阅this问题。使用gen_text.collocation_list()可能会解决这个问题。
