tensorflow deep reinforcement learning ddpg program error solving

Part of the answer refers to GPT, GPT_Pro better addresses the problem
AttributeError 'CartPoleEnv' object has no attribute monitor, which is due to an error caused by not defining the monitor attribute in the CartPoleEnv class.

Solution: 1. Confirm whether the monitor attribute is defined in the code. If not, you need to define the monitor attribute and assign a value.
2. It is also possible that some variable or function names in the code are incorrectly named and duplicate the attribute names in CartPoleEnv. In this case, you can change the variable or function names.

class CartPoleEnv:
    # 其他代码

    def __init__(self):
        # 其他代码
        self.monitor = False # 定义monitor属性并赋值
