imread()读入图像默认的数据类型为uint8,符号除法得到的数据类型发生了改变,变成了float64。 当除数为0时,numpy除法打印了告警信息:divide by zero encountered in true_divide,直接计算结果为inf,但是转换为OpenCV的图像是有实际意义的0。 3、divide()除法中的0 从前面计算结果看,当有元素为0且作为被除数时,divid...

1. 解释“invalid value encountered in divide”错误的意义 “invalid value encountered in divide”是一个运行时警告(RuntimeWarning),通常出现在Python中使用numpy进行除法运算时。这个警告表明在进行除法运算时遇到了无效值,最常见的原因是尝试将某个数除以零(0/0)或者除以一个非数字值(如NaN)。 2. 分析导致“...
RuntimeWarning: invalid value encountered in true_divide “”"Entry point for launching an IPython kernel. 遇到问题解决问题,解决方法有很多。 法1: 忽略warn np.seterr(divide='ignore',invalid='ignore') 1 法2: 具体问题具体分析,这里是预算。没有倒贴钱的情况,过去为0的意思是过去没有这项,现在为0...
代码(Python3) class Solution: def divide(self, dividend: int, divisor: int) -> int: # 只有这种情况会出现溢出, # 因为 32 位有符号整数的范围是 [-(2 ^ 31), 2 ^ 31 - 1] , # 此时结果为 2 ^ 31 ,超过了 32 位有妇好整数的最大值, # 需要返回 2 ^ 31 - 1 。 if divisor == ...
