无法在线性回归中导入MultiOutputMixin

Question

我试图运行线性回归模型，该模型由A Geron使用Scikit Learn和Tensorflow进行了机器学习的第二章。但是我得到了这个Can't import MultiOutputMixin error。

有人可以帮我这个忙吗？我已经在Azure笔记本（基本上是木笔记本）中编写了代码。

代码如下：

from sklearn.linear_model import LinearRegression,MultiOutputMixin
from sklearn.linear_model.base import MultiOutputMixin

lin_reg=LinearRegression()

lin_reg.fit(housing_prepared,housing_labels)

错误：

_ImportError Traceback (most recent call last)

4 lin_reg=LinearRegression()
