Question

def words_to_indices(inverse_vocabulary, words):
    return [inverse_vocabulary[word] for word in words]

if __name__ == "__main__":
    vocabulary = open("G:\clickbait-detector-master\data/vocabulary.txt").read().split("\n")
    inverse_vocabulary = dict((word, i) for i, word in enumerate(vocabulary))

    clickbait = open("G:\clickbait-detector-master\data/clickbait.preprocessed.txt").read().split("\n")
    clickbait = sequence.pad_sequences([words_to_indices(inverse_vocabulary, sentence.split()) for sentence in clickbait], maxlen=SEQUENCE_LENGTH)

    genuine = open("G:\clickbait-detector-master\data/genuine.preprocessed.txt").read().split("\n")
    genuine = sequence.pad_sequences([words_to_indices(inverse_vocabulary, sentence.split()) for sentence in genuine], maxlen=SEQUENCE_LENGTH)

我的错误是：

KeyError                                  Traceback (most recent call last)

KeyError: 'C'

Answer 1

我不知道您要如何处理缺少的值，但是错误告诉您它来自于此：

def words_to_indices(inverse_vocabulary, words):
    return [inverse_vocabulary[word] for word in words]

具体来说，问题是inverse_vocabulary[word]，当您提供的密钥不存在时，它将抛出KeyError，在这种情况下，引发错误的密钥是C。

由于我不知道您要如何处理不存在的缺失键，因此我将向您展示一种处理这种情况的方法，以免引发错误。

def words_to_indices(inverse_vocabulary, words):
    return [inverse_vocabulary.get(word, '{} does not exist'.format(word) for word in words]

在这种情况下，words_to_indices的输出应如下所示：

['val1', 'val2', 'val3', 'C does not exist', etc...]

您必须对其进行修改才能执行您想要的操作。

我在编译时遇到关键错误
