Python中"divide by zero encountered in log"错误的含义 在Python中,当尝试对0或负数执行对数运算时,会触发"divide by zero encountered in log"错误。这是因为对数函数的定义域是正数,不包括0和负数。对数运算本质上可以看作是一种特殊的除法运算,即求以某个正数为底、以目标数为真数的幂运算的指数。当目标数...
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。)...

@ogriselI think we might be running into#18005, i.e. clang has theterribledefault of not using-ffp-exception-behavior=strict! There are already a few places in the code working around that I think. Try setting the flag if that fixes it. We really should force that flag, but I am not...
