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

Problem: I assume that due to the massive size of the for loop (= 21073) I always get the error RuntimeWarning: divide by zero encountered in log10. Importantly, the position in the for loop where this error occurs varies every time I run the code again. That is,...

The NumPy "RuntimeWarning: divide by zero encountered in log10" is shown when you pass an array that contains zeros to the `numpy.log10()` method.
