python - 在 Jupyterlab 中导入 sklearn.compose.make_column_selector 时遇到问题

Question

我在从 SciKit Learn 导入 make_column_selector 方法时遇到了一些问题。这是我的代码和由此产生的错误:

from sklearn.compose import ColumnTransformer
from sklearn.compose import make_column_selector
from sklearn.impute import SimpleImputer
from sklearn.impute import MissingIndicator
from sklearn.preprocessing import OneHotEncoder
from sklearn.pipeline import Pipeline
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression

ImportError                               Traceback (most recent call last)
<ipython-input-25-c801fe55616f> in <module>
      1 from sklearn.compose import ColumnTransformer
----> 2 from sklearn.compose import make_column_selector
      3 from sklearn.impute import SimpleImputer
      4 from sklearn.impute import MissingIndicator
      5 from sklearn.preprocessing import OneHotEncoder

ImportError: cannot import name 'make_column_selector' from 'sklearn.compose' (C:\Users\azhad\Anaconda3\lib\site-packages\sklearn\compose\__init__.py)

为了确认，我已经用 SciKitLearn 版本 0.23 更新了 anaconda。有没有人遇到过这个错误？有知道的请反馈一下，谢谢!

在 scikitlearn 0.21 版本上遇到同样的错误。升级到最新版本 (0.24.2) 后，它运行良好。
