ImportError: cannnot import name 'Imputer' from 'sklearn.preprocessing'

Question

Trying to import Imputer from sklearn,

import pandas as pd
dataset = pd.read_csv(\'Data.csv\')
X = dataset.iloc[:, :-1].values
y = dataset.iloc[:, 3].values
         


        

Answer 1

Try this:

from sklearn.impute import SimpleImputer

imr = SimpleImputer(missing_values=np.nan, strategy='mean')

imr = imr.fit(df.values)

imputed_data = imr.transform(df.values)

print (imputed_data)

Note: New changes are in boldface for your quick reference.

Answer 2

The class is deprecated, use

from sklearn.impute import SimpleImputer
imputer = SimpleImputer(missing_values=np.nan, strategy='mean')

Answer 3

After the version scikit-learn SimpleImputer/Imputer has been changed its location from sklearn.preprocessing to package sklearn.impute.

So, kindly use the below line of code to import.

from sklearn.impute import SimpleImputer

Thank you!
