已解决（机器学习中查看数据信息报错）AttributeError: target

成功解决（机器学习中查看数据信息报错）：AttributeError: target_names

• 报错代码
• 报错原因
• 解决方法

我的代码：

from sklearn import datasets

diabetes = datasets.load_diabetes(return_X_y=False, as_frame=True)
print(diabetes.target_names)

报错内容：

Traceback (most recent call last):
  File "D:Python3.8libsite-packagessklearnutils__init__.py", line 117, in __getattr__
    return self[key]
KeyError: 'target_names'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "E:/Python/1.py", line 6, in 
    print(diabetes.target_names)
  File "D:Python3.8libsite-packagessklearnutils__init__.py", line 119, in __getattr__
    raise AttributeError(key)
AttributeError: target_names

target_names是标签名，sciket-learn数据集API中，回归数据集没有标签名，其他数据集才有

查看其他内容如：特征名、新闻数据、手写数字

from sklearn import datasets

diabetes = datasets.load_diabetes(return_X_y=False, as_frame=True)
print(diabetes.feature_names)

运行结果：

['age', 'sex', 'bmi', 'bp', 's1', 's2', 's3', 's4', 's5', 's6']
