我正在尝试differential_evolution从 SciPy 使用。我有三个矩阵：x、y 和 P - 大小均为 (14,6)。我必须使用以下公式：
z= np.log10(g)+ np.log10(c)*np.log10(P)
找到最小化的 c 值（从 0 到 2 的实数）：
numpy.median(z**2)
这个表达。我尝试的是这个（为方便起见，我提供了数据）：
import numpy as np
from scipy.optimize import differential_evolution
def func(c, args):
z = args[0] + np.log10(c)*np.log10(args[1])
return np.median(z**2)

我得到这个错误：TypeError: func() takes exactly 2 arguments (3 given)。有没有什么办法解决这一问题？
