NLTK BigramTagger错误列表(list(tuples()))

所以我有一个如下所示的列表:

list[[tuple(),tuple(),tuple()], [tuple(),tuple(),tuple()]]

所以基本上是一个列表列表,其中每个内部列表包含元组(word,tag)。 当我尝试训练Bigram Tagger时,它会返回错误

list := list[[tuple(),tuple(),tuple()], [tuple(),tuple(),tuple()]]
bigram_tagger = nltk.BigramTagger(list)

给我回复错误:

Traceback (most recent call last):
File "PATH/project.py", line 123, in <module>

TypeError: unhashable type: 'list'

1 个答案:

答案 0 :(得分:0)

可能是命名约定错误。通常关键词如&#39; list&#39;不应该用于变量名。

这就是为什么你可能会得到这个

TypeError: unhashable type: 'list'
