一元线性回归，pandas出问题

1.csv的文件，名称是”销售额“

2.问题相关代码

import matplotlib.pyplot as plt
import pandas as pd
from sklearn.linear_model import LinearRegression

data = pd.read_csv("./销售额.csv")
x = data['活动推广费']
y = data['销售额']

x = x.values.reshape(-1,1)
y = y.values.reshape(-1,1)

model = LinearRegression()
model.fit(x,y)

predict_y = model.predict(x)

predictions = {}
predictions['intercept'] = model.intercept_
predictions['coefficient'] = model.coef_
predictions['predict_value'] = predict_y

plt.scatter(x,y,color = 'blue')
plt.plot(x,predict_y,color = 'red',linewidth = 4)

plt.title('预测销售额')
plt.xlabel('活动推广费')
plt.ylabel('销售额')
plt.show()

3.运行结果及报错内容

4.我想要达到的结果：出一个一元线性回归图

你看看你的csv是什么编码格式，要读取的时候要设置一下，具体可以参考
