【问题描述】:
我正在尝试使用 Spacy 模块对亚马逊产品评论进行情绪分析,以预处理文本数据。我使用的代码正是this。我根据链接中显示的内容修改了我正在使用的数据集。我收到了错误:

我不确定是什么导致了这个错误以及如何摆脱它。我很确定计数矢量化器会产生一个稀疏矩阵,而不是一个字符串。我考虑过的一件事是我正在使用 spacy 标记器,它在链接中用作vectorizer = CountVectorizer(tokenizer = spacy_tokenizer, ngram_range=(1,1)) 但是当我运行程序时它说 spacy_tokenizer 未定义。所以我改用vectorizer = CountVectorizer(tokenizer = 'spacy', ngram_range=(1,1))。但是,如果我删除它,那么我不知道如何使用 spacy 标记器,无论哪种方式,我都不确定这确实是问题的原因。请帮帮我!
