DDPG（4）_ounoise

1、应用python库

import numpy as np
import numpy.random as nr

2、定义类

class OUNoise:
    """docstring for OUNoise"""
    def __init__(self,action_dimension,mu=0, theta=0.15, sigma=0.2):
        self.action_dimension = action_dimension
        self.mu = mu
        self.theta = theta

（以下为Class OUNoise中的函数）

2.1 初始化

    def __init__(self,action_dimension,mu=0, theta=0.15, sigma=0.2):
        self.action_dimension = action_dimension
        self.mu = mu
        self.theta = theta
        self.sigma = sigma
        self.state = np.ones(self.action_dimension) * self.mu
        self.reset()

维度与动作一致，初始化一些参数。

2.2 重置

    def reset(self):
        self.state = np.ones(
