运行时警告：在双标量中遇到溢出将停止执行cod

Question

当我试图执行这段代码时 我用的是jupyter笔记本

for i in range(0,train_len):
    avg = (x1[i] + x2[i] + x3[i] + x4[i])/4
    h = x0*w0 + x1[i]*w1 + x2[i]*w2 + x3[i]*w3 + x4[i]*w4  
    error = avg - h
    w0 = w0 + n*error
    w1 = w1 + n*x1[i]*error
    w2 = w2 + n*x2[i]*error
    w3 = w3 + n*x3[i]*error
    w4 = w4 + n*x4[i]*error

这遇到了这个错误

^{pr2}$

我该怎么解决这个问题？在
