问题描述
尝试从 sklearn 导入 Imputer，
Trying to import Imputer from sklearn,
import pandas as pd
dataset = pd.read_csv('Data.csv')

y = dataset.iloc[:, 3].values
#PART WHERE ERROR OCCURS:-
from sklearn.preprocessing import Imputer
显示ImportError: cannot import name 'Imputer' from 'sklearn.preprocessing' (/home/codeknight13/anaconda3/lib/python3.7/site-packages/sklearn/preprocessing/__init__.py)"

推荐答案
from sklearn.preprocessing import Imputer 已被 scikit-learn v0.20.4 弃用并从v0.22.2.
from sklearn.impute import SimpleImputer
imputer = SimpleImputer(missing_values=np.nan, strategy='mean')
