ImportError：无法从“sklearn.inspection”导入名称“DecisionBoundaryDisplay”

Question

I imported sklearn DecisionBoundaryDisplay via the below command in my Google Colab file.

from sklearn.inspection import DecisionBoundaryDisplay

And I'm getting the following error.

ImportError: cannot import name 'DecisionBoundaryDisplay' from 'sklearn.inspection'

I even installed the following packages & also tried by restarting my runtime but still I'm getting the error.

!pip install --upgrade scikit-learn

!pip install scipy

!pip3 install -U scikit-learn scipy matplotlib

How to fix this issue?

Answer 1

It seems DecisionBoundaryDisplay is a new feature and it is currently in an unstable development version. To use it, you need to install the nightly build .

Answer 2

what worked for me was installing scikit learn 1.1.0, i had version 1.0.2 before and got the same error you're encountering.

pip install -U scikit-learn --user

Hope it helps.

Answer 3

thank you.

pip install -U scikit-learn --user

the above command worked and the error gone. decision boundaries are plotted. ImportError: cannot import name 'DecisionBoundaryDisplay' from 'sklearn.inspection' (D:\anaconda\lib\site-packages\sklearn\inspection_ init _.py)
