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
RuntimeWarning: divide by zero encountered in log警告的含义: 这个警告表明在尝试执行对数运算(如np.log(), math.log()等)时,遇到了除数为零的情况。对数运算的定义域是正数,不包括零和负数,因此任何尝试对零或负数取对数的操作都会导致此警告。 指出可能导致该警告的代码情况: 当在代码中直接对可能为零的变...

Steps to handle type exception in Python The steps to handle type exception in Python are: Step 1:We will take inputs from the user, two numbers. Step 2:If the entered data is not integer, throw an exception. Step 3:If the remainder is 0, throw divide by zero exception. ...
Generally, the values are not divisible by 0 and infinity. In Python, NumPy is a module which is used for numerical analysis and performs the mathematical operations on arrays. When you try to divide by NaN/0/Inf, you get the “nan” result with the “Invalid value encountered in true_...
In x, y and# distance_from_origin, only one point in distance_from_origin can# be 0.0 (circle center) and in this point x and y must be 0.0 as# well. So here is a hack to avoid the 'invalid value encountered# individe' error by turning 0.0 to 1e-5 in distance_from_origin....
