RuntimeWarning: overflow encountered in scalar add 的解释RuntimeWarning: overflow encountered in scalar add 是Python 运行时发出的一种警告,指示在执行标量加法时发生了溢出。这通常意味着在执行加法操作时,结果超出了所使用数据类型(如整数或浮点数)的表示范围。 可能导致该警告的原因 数据类型限制:当使用固定范...
RuntimeWarning: overflow encountered in exp 在使用逻辑斯蒂回归时,报了栈溢出错误。def logistic(x): return 1.0 / (1 + np.exp(-x))RuntimeWarning: overflow encountered in exp return 1.0 / (1 + np.exp(-x))参照网上的做法,对x做判断,def logistic(x):...
在自定义神经网络中,使用sigmoid函数时,报数据溢出overflow错误。 defsigmoid(self, x):return1.0/ (1+ np.exp(-x)) RuntimeWarning: overflow encountered in exp 根据测试(测试代码如下),是因为指数出现极大的数据,导致np.exp运算溢出 defsigmoid(self, x):print(x.min())return1.0/ (1+ np.exp(-x)) ...
