这行代码可能是类似result = self * some_value的乘法操作。 理解导致RuntimeWarning: overflow encountered in multiply警告的原因: 这个警告通常表示在进行乘法操作时,结果超出了当前数据类型的表示范围。例如,如果你使用int8或int16类型来存储计算结果,而实际结果超出了这些类型的最大值,就会发生溢出。 分析self对象...
Hi I let eval_iters = 50, I encountered a problem(RuntimeWarning: overflow encountered in multiply). With the number of eval_iters' increase, I only want to have the minimized RMSE. But I don't know how to solve the problem. Here is the ...

RuntimeWarning: overflow encountered in exp 这是因为参数值inx很大时,exp(inx)可能会发生溢出,解决方法是对sigmoid函数实现的优化,具体代码如下: 1 2 3 4 5 defsigmoid(inx): ifinx>=0:#对sigmoid函数的优化,避免了出现极大的数据溢出 return1.0/(1+exp(-inx)) ...

An overflow prediction scheme is provided to operate in parallel with an integer multiply within a computer to predict overflow conditions of the resultant register. The operands to be multiplied are examined to determine the position of the most significant bit. The position values are summed to ...
