数据预处理-缺失值

Class Imputer is deprecated; Imputer was deprecated in version 0.20 and will be removed in 0.22. Import impute.SimpleImputer from sklearn instead.

阶级归算是不受欢迎的;Imputer在0.20版本中被弃用，将在0.22版本中被删除。进口转嫁。而是来自sklearn的简单输入。

数据预处理

用均值补充缺失值

import numpy as np
from sklearn.impute import SimpleImputer
imputer = SimpleImputer(missing_values=np.nan,strategy='mean')
imputer = imputer.fit(X[:,1:10])
X[:,1:10] = imputer.transform(X[:,1:10])

图片输出为数据集[7:10]列的内容
