Machine learning FastText类使用未定义的对象

我在读一篇我在这里找到的文章时遇到了FastText类

作者使用了一个未定义的对象“word_tokenized_corpus”

---

我犯了一个错误，原因很明显。如何正确启动该类？

作者已对文章进行了更新，并添加了以下代码：

final_corpus = [
    preprocess_text(sentence)
    for sentence in artificial_intelligence
    if sentence.strip() != ""
]

word_punctuation_tokenizer = nltk.WordPunctTokenizer()
word_tokenized_corpus = [
    word_punctuation_tokenizer.tokenize(sent) for sent in final_corpus
]

final_corpus = [
    preprocess_text(sentence)
    for sentence in artificial_intelligence
    if sentence.strip() != ""
]

word_punctuation_tokenizer = nltk.WordPunctTokenizer()
word_tokenized_corpus = [
    word_punctuation_tokenizer.tokenize(sent) for sent in final_corpus
]
