stable_baselines module error -> ‘gym.logger’ has no attribute ‘MIN_LEVEL’

原文标题 ：stable_baselines module error -> ‘gym.logger’ has no attribute ‘MIN_LEVEL’

我正在尝试使用 stable_baselines，但我尝试使用的任何模型都会给我同样的错误：

模块“gym.logger”没有属性“MIN_LEVEL”

我附上了他们网站上的一个例子，它给了我同样的错误。我尝试在网上查找，但没有任何成功。另外，我目前正在使用 Conda 创建具有以下设置的环境。

张量流：1.15.0Python：3.7.11

代码如下。

import gym

from stable_baselines.common.policies import MlpPolicy
from stable_baselines.common import make_vec_env
from stable_baselines import PPO2

# multiprocess environment
env = make_vec_env('CartPole-v1', n_envs=4)

model = PPO2(MlpPolicy, env, verbose=1)
model.learn(total_timesteps=25000)
model.save("ppo2_cartpole")

del model # remove to demonstrate saving and loading

model = PPO2.load("ppo2_cartpole")

# Enjoy trained agent
obs = env.reset()
while True:
    action, _states = model.predict(obs)
    obs, rewards, dones, info = env.step(action)
    env.render()

完整错误：
