原因:数字太小的原因,溢出,计算过程中出现-inf,再做其他运算,结果还是-inf。当概率很小时,取对数后结果趋于负无穷大 解决:改变浮点数的精度 参考:(51条消息) RuntimeWarning: divide by zero encountered in log错误解决_旅途中的宽~的博客-CSDN博客

但是,RuntimeWarning: divide by zero encountered in log10仍然出现,我确定是这一行引起了警告。 虽然我的问题解决了,但我很困惑为什么这个警告一次又一次出现? 计算prob的所有元素的以 10 为底的对数,即使是where未选择的元素如果需要,您可以在取对数之前用10**-10或一些虚拟值填充probprob > 0.0000000001。)...

In Python, aZeroDivisionErroris raised when a division or modulo operation is attempted with a denominator or divisor of 0. What Causes ZeroDivisionError AZeroDivisionErroroccurs in Python when a number is attempted to be divided by zero. Since division by zero is not allowed in mathematics, attemp...

我有一个数据帧,其中我取一个df的前7列的row-wise平均值,然后除以另一个。然而,这个数据集中有很多零,我想用零代替零除法错误(因为这对我来说很有意义),而不是自然返回的nan(因为我正在实现它)。 到目前为止我的代码是: col_ind = list(range(0,7)) ...
