sklearn.preprocessing.Imputer について

Posted at

現在(2020/03/03),COVID-19の感染拡大に伴う小中高校の休校を受け,N予備校の教材がすべて無料公開されています.僕も「機械学習 入門」に手を付けているとことでありますが,「12.欠損値の扱い方」でちょっとしたトラブルが発生.

エラー

ImportError: cannot import name 'Imputer' from 'sklearn.preprocessing'

僕の使っているscikit-learnのversionは0.22.2なのですが,このバージョンではsklearn.preprocessing.Imputerがサポートされていないようです.


解決策を調べました.

from sklearn.impute import SimpleImputer

を使えば良いようです.
