使用Sklearntutorial，无法承担vectorizer.get_feature_names_out（）的输出
我的20newSgroups_train数据的输出部分是吗？还是来自默认库？因为“ zz_g9q3”之类的单词没有意义。 当前使用20NewSgroups_train数据集和20newsgroups_test数据
集输入：
vectorizer=TfidfVectorizer()
vectors_test=vectorizer.transform(newsgroups_test.data)
print(vectorizer.get_feature_names_out()[-50:])
输出：
['zyra' 'zysec' 'zysgm3r' 'zysv' 'zyt' 'zyu' 'zyv' 'zyxel' 'zyxel1496b'
'zz' 'zz20d' 'zz93sigmc120' 'zz_g9q3' 'zzcrm' 'zzd' 'zzg6c' 'zzi776'

Is the output part of my 20newsgroups_train data? or is it from a default library? Because the words like 'zz_g9q3' dont make sense.
currently using 20newsgroups_train dataset and 20newsgroups_test datasets
Input:
vectorizer=TfidfVectorizer()
vectors_test=vectorizer.transform(newsgroups_test.data)
print(vectorizer.get_feature_names_out()[-50:])
Output:
['zyra' 'zysec' 'zysgm3r' 'zysv' 'zyt' 'zyu' 'zyv' 'zyxel' 'zyxel1496b'
