windows系统下安装最新版gym的安装方法（此时最新版的gym为0.24.0，gym==0.24.0)

当前gym的最新版本为0.24.0，本篇介绍对gym[atari]==0.24.0进行安装。

 

 

使用pip安装：

pip install gym[atari]

 

 

 

 

 

可以看到此时安装的是ale_py而不是atari_py库。

 

 

运行测试代码：

 

import gym
env=gym.make("Pong-v0")
print(env)
env.reset()

 

结果报错：

 

f'We\'re Unable to find the game "{self._game}". Note: Gym no longer distributes ROMs. '
gym.error.Error: We're Unable to find the game "Pong". Note: Gym no longer distributes ROMs. If you own a license to use the necessary ROMs for research purposes you can download them via `pip install gym[accept-rom-license]`. Otherwise, you should try importing "Pong" via the command `ale-import-roms`. If you believe this is a mistake perhaps your copy of "Pong" is unsupported. To check if this is the case try providing the environment variable `PYTHONWARNINGS=default::ImportWarning:ale_py.roms`.

根据报错的信息我们知道是因为没有安装atari游戏对应的ROMs的bin文件，我们可以选择手动下载后添加到ale_py库中，但是根据报错信息的提醒我们知道可以使用命令：pip install gym[accept-rom-license] 来进行安装。

执行：

pip install gym[accept-rom-license]

 

此时再运行，结果：

 

 证明问题已解决，gym[atari]已经成功安装。

 

 

 

 

 

测试代码：

绘图版：

 

import time
import gym

env = gym.make('BreakoutNoFrameskip-v4', render_mode='human')
print("Observation Space: ", env.observation_space)
print("Action Space       ", env.action_space)

obs = env.reset()
for i in range(1000):
    # env.render()
    action = env.action_space.sample()
    obs, reward, done, info = env.step(action)
    time.sleep(0.01)
env.close()
