RuntimeWarning: invalid value encountered in power 是Python 在进行幂运算时发出的一个警告,表明在运算过程中遇到了无效值。这通常发生在计算结果的数学定义不明确或超出了浮点数的表示范围时。 2. 常见原因 负数的非整数次幂:在实数范围内,负数的非整数次幂没有明确的数学定义,因此会触发此警告。 零的零次幂:虽...
RuntimeWarning: invalid value encountered in scalar power这个警告表示在执行标量幂运算((profit / initial_cash) ** (1 / yy) - 1) * 100时遇到了无效值。常见的引发原因及解决办法如下: 原因分析 负数开偶次根:当profit / initial_cash的值为负数,同时1 / yy计算结果为分母是偶数的分数(相当于开偶次根...
