程序如下：
import sys
sys.path
sys.path.append('D:\P.ython 3.8.0_x64\Lib\site-packages')
from sklearn.feature_extraction.text import CountVectorizer ,TfidfVectorizer#默认返回稀疏矩阵
from sklearn.preprocessing import MinMaxScaler
import jieba
import pandas as pd
def minmax_demo():
#归一化
#1获取数据
data=pd.read_csv('dating.txt')
data=data.iloc[:,:3]
print('data\n', data)
#2.实例化
transfer=MinMaxScaler()
#3.调用fit_transform
data_new=transfer.fit_transform(data)
print(data_new)
return None
if name == 'main':
minmax_demo()
报错：
