python运行错误runfile('F:/untitled3.py', wdir='F:')

import pandas as pd
from sklearn.impute import SimpleImputer
data=pd.read_csv('D:\BaiduNetdiskDownload\SalesData.csv')
data=data.sample(n=500,random_state=28)
imp_mode = SimpleImputer(strategy='most_frequent')
Order_Priority=data.loc[:,'Order Priority'].values.reshape(-1,1)
data.loc[:,'Order Priority'] = imp_mode.fit_transform(Order_Priority)
Sales=data.loc[:,'Sales'].values.reshape(-1,1)
data.loc[:,'Sales'] = imp_mode.fit_transform(Sales)
data.to_csv('Cleaned_SalesData.csv',index=False) #保存数据

是哪里出现问题了啊，为什么运行不了呢
