使用python语言，借助sklearn库实现了多元线性回归的训练和预测(The training and prediction of multiple linear regression are realized by using Python language and sklearn Library)

利用最小二乘法求多元线性回归，里面的数据是用pickle打包好的，当你需要其他数据时可以将其中的数据代入xy(Using the least square method to get multiple linear regression, the data inside is packed in pickle, and can be replaced by XY when you need other data.)
