python 实现对数据集的归一化的方法(0-1之间)

 #首先，引入两个库 ，numpy,sklearn
from sklearn.preprocessing import MinMaxScaler
import numpy as np
 #将csv文件导入矩阵当中
my_matrix = np.loadtxt(open("xxxx.csv"),delimiter=",",skiprows=0)
 #将数据集进行归一化处理
scaler = MinMaxScaler( )
scaler.fit(my_matrix)
scaler.data_max_
my_matrix_normorlize=scaler.transform(my_matrix)

 #最后的my_matrix_normorlize 实现了归一化my_matrix_normorlize

from sklearn.preprocessing import MinMaxScaler
import numpy as np
my_matrix = np.loadtxt(open("xxxx.csv"),delimiter=",",skiprows=0)
scaler = MinMaxScaler( )
scaler.fit(my_matrix)
scaler.data_max_
my_matrix_normorlize=scaler.transform(my_matrix)
