Reference Issues/PRs
In issue #24916, we want to make the error message uniform in estimators when we call
get_feature_names_outbeforefit. This PR works towards that issue and solves the inconsistencies in estimators that inherit from theOnetoOneFeatureMixinClass.What does this implement/fix? Explain your changes.
The following estimators that inherit from the
OnetoOneFeatureMixinclass will raise the agreedNotFittedErrorwhenget_feature_names_outis called beforefit.Any other comments?
All tests successfully passed after the above estimators were removed from the whitelist.
