这个错误是因为在使用TfidfVectorizer时,调用了get_feature_names_out方法,是该方法已经被弃用了。正确的方法是使用get_feature_names()方法来获取特征名称。下面是一个例子:
```python
from sklearn.feature_extraction.text import TfidfVectorizer
# 创建TfidfVectorizer对象
vectorizer = TfidfVectorizer()
# 假设有一些文本数据
corpus = ['This is the first document.', 'This is the second second document.', 'And the third one.', 'Is this the first document?']
# 将文本数据转换为tf-idf向量
X = vectorizer.fit_transform(corpus)
# 获取特征名称
feature_names = vectorizer.get_feature_names()
# 打印特征名称
print(feature_names)
```
输出结果为:
```
['and', 'document', 'first', 'is', 'one', 'second', 'the', 'third', 'this']
```
