导入错误：无法从“sklearn.preprocessing”导入名称“Imputer”

Question

尝试从 sklearn 导入 Imputer，

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

Answer 1

from sklearn.preprocessing import Imputer已弃用scikit-learn v0.20.4并从v0.22.2.

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