分类的决策边界

Question

I have trained my machine learning classification model in Python. For the result analysis when I am trying to draw a decision surface or boundary in google colab using sklearn(scikit-learn) inspection module

from sklearn.inspection import DecisionBoundaryDisplay

I am getting the following error.

I have upgraded sklearn

pip install -U scikit-learn

After the upgrade sklearn version is 1.0.2

why am I encountering the error and what is the solution to this problem?

Answer 1

sklearn v1.0.2 does not have DecisionBoundaryDisplay: https://scikit-learn.org/1.0/modules/classes.html#module-sklearn.inspection

sklearn v1.1.3 does: https://scikit-learn.org/stable/modules/classes.html#module-sklearn.inspection
