python中sklearn中的Imputer模塊改動

try:
    from sklearn.impute import SimpleImputer # Scikit-Learn 0.20+
except ImportError:
    from sklearn.preprocessing import Imputer as SimpleImputer

imputer = SimpleImputer(strategy="median")

隨着版本的更新，Imputer的輸入方式也發生了變化，一開始的輸入方式爲

from sklearn.preprocessing import Imputer
imputer = Imputer(strategy='median')

現在需要對上面輸入進行更新，輸入變爲

from sklearn.impute import SimpleImputer
imputer = SimpleImputer(strategy="median")
