运行时警告：在numpy

Question

我一直试图在一个变量中编写我自己的Pyhton程序进行线性回归，如Coursera所示。我写了以下代码 -

def ComputeCost(X,y,init_Theta):
        calculated_cost = (1./2*m)*(np.dot(np.transpose((H_Theta(X,init_Theta)-y)),(H_Theta(X,init_Theta)-y)))
        return calculated_cost

此函数以下列方式用于LinearRegression函数：

for i in range(iterations):  
    tempTheta = theta
    calculated_cost = ComputeCost(X,y,tempTheta)   
    print(calculated_cost)

该程序给了我这个错误：

calculated_cost = (1./2*m)*(np.dot(np.transpose((H_Theta(X,init_Theta)-y)),   (H_Theta(X,init_Theta)-y)))
RuntimeWarning: overflow encountered in multiply

请在这方面帮助我。
