Question

我正在尝试在 0.9.5 版本上安装gym atari 包（我特别需要这个版本），但是当我运行代码时（如果正确下载了gym 应该可以顺利运行），我收到以下错误:

AttributeError: 'AtariEnv' object has no attribute 'viewer'

当我尝试运行 gym.make() 时出现问题。

有人知道如何解决这个问题吗？

我在 python 3.9 上发生了同样的行为，但由于某种原因在 python 3.8 上没有发生（那里有一个不同的错误）。也许我缺少一些渲染库？

完整的错误信息是：

还有相关代码：

if __name__ == '__main__':
    # Get Atari games.
    benchmark = gym.benchmark_spec('Atari40M')
    
    # Change the index to select a different game.
    task = benchmark.tasks[3]
    
    # Run training
    seed = 0 # Use a seed of zero (you may want to randomize the seed!)
    env = get_env(task, seed)

而 get_env 是：

def get_env(task, seed):
    env_id = task.env_id

    env = gym.make(env_id)

    set_global_seeds(seed)
    env.seed(seed)

    expt_dir = 'tmp/gym-results'
    env = wrappers.Monitor(env, expt_dir, force=True)
    env = wrap_deepmind(env)

    return env

在 Windows 上的 python 中使用健身房 atari（版本 0.9.5）
