用python写出内点法优化算法的代码

下面是一个内点法优化算法的简单实现：

import numpyas np

def interior_point(obj, grad_obj, hess_obj, constraints, x0, rho=0.5, sigma=0.7, epsilon=1e-5):
    x = x0.copy()
    n = x0.shape[0]
    mu = rho
    while True:
        # 更新拉格朗日乘数
        grad_f, jac = grad_obj(x, mu), constraints(x, mu)
        hess = h
