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

I'm having an issue debugging my SQL code to find out why I'm producing a "divide by zero error encountered". I believe that this error occurs when trying to divide by a null value and using NULLIF as I understand is a way to prevent this. I have been unsuccessful in my attempts ...

在执行涉及log运算的代码时,遇到RuntimeWarning: divide by zero encountered in log10,通常是因为数据中的某些值非常接近于0或等于0,导致对数运算无法进行。? 这种问题常见于数据处理和机器学习任务中,尤其是在进行对数运算时。如果数据中存在0或非常接近0的值,尝试对这些值进行对数运算会导致“divide by zero”错误...
