def get_feature_names_support(self): # 在这里实现get_feature_names方法的逻辑 pass 在该自定义向量化器类中,我们实现了get_feature_names方法的逻辑。在该方法中,我们首先创建一个副本,然后使用TfidfVectorizer类中的get_feature_names方法,并返回一个特征名称列表。 需要注意的是,在该自定义向量化器类中,我们...
当在Python 的一个 IT 领域相关项目里遇到此错误时,通常意味着countvectorizer对象尚无 'get_feature_names' 属性。为了解决这个问题,首先需要检查countvectorizer对象是否处于正确的导入环境中。接着,可以尝试导入countvectorizer对应的包,并检查get_feature_names方法是否存在。如果问题仍然存在,可以通过countvectorizer.get_fe...
AttributeError: 'DictVectorizer' object has no attribute 'get_feature_names_' 这个错误通常是由于使用了不匹配的版本或错误的库导致的。在这种情况下,可能是因为您使用的是DictVectorizer对象,而它不具有get_feature_names_属性。 要解决这个问题,您可以尝试以下几个步骤: 确保您正在使用正确版本的库。如果您使用的...
