我正在尝试运行 OpenAI Gym 环境，但是出现以下错误：

Answer 1

pip install gym[atari,accept-rom-license]==0.21.0

Answer 2

这通过终端对我有用：

pip install gym[atari]
pip install autorom[accept-rom-license]

安装gym后为80场。安装gym[atari]后，是267个游戏。并且您必须接受特定许可证才能激活其他游戏。

Answer 3

代码适用于我

gym

0.18.0

和

0.19.0

但不适用于

0.20.0

你可以降级它

pip install --upgrade gym==0.19.0

顺便说一句：它可能还需要安装

gym[atari]

或

gym[all]

才能使所有元素正常工作。

根据 0.21.0 Release Note 中的信息（在

pip

上还没有准备好，但您可以从 GitHub 安装）

ALE

(

Arcade Learning Environment

) 中有一些变化，它造成了所有问题，但它是固定在

0.21.0

.

-上一个版本损坏的旧 Atari 入口点和 ALE-Py 的升级已修复

但是新的

gym[atari]

不安装ROM，您将需要使用模块AutoROM

-pip install gym[atari] 不再分发 ALE（使用的 Atari 模拟器）运行各种游戏所需的 Atari ROM。将 ROM 安装到 ALE 中的最简单方法是使用 AutoROM。

编辑：

来自 GitHub 的版本

0.21.0

安装后对我有用

（它可能需要程序

git

）

pip install --upgrade git+https://github.com/openai/gym
pip install autorom

AutoRom    

pip install --upgrade gym[atari]

AutoRom 运行程序，询问您是否有 ROM 许可证并在

AutoROM/roms

中安装 ROM，但我不必将 ROM 移动到其他地方。

AutoROM will download the Atari 2600 ROMs.
They will be installed to:
    /usr/local/lib/python3.8/dist-packages/AutoROM/roms

Existing ROMs will be overwritten.

I own a license to these Atari 2600 ROMs.
I agree to not distribute these ROMs and wish to proceed: [Y/n]:

Answer 4

对于在 2023 中使用新的

Gymnasium

叉子的任何人，我已经使用以下步骤在我的 mac 上本地设置了

Breakout

：

创建具有以下依赖项的

requirements.txt

文件：

 gymnasium[atari, all]

 swig

 Box2D

 box2d-kengz

 pygame

 ale_py

 autorom

创建一个 python 虚拟环境并通过运行安装依赖项：

 python3 -m venv .venv

 source .venv/bin/activate

 pip install -r requirements.txt

运行以下命令接受许可证
```
 AutoROM --accept-license
```

如果您在此步骤中遇到任何超时问题，请查看此 github issue 以获取一些提示。

运行以下python代码启动环境

 import gymnasium as gym
 import ale_py

 from gymnasium.utils import play

 print('gym:', gym.__version__)

 print('ale_py:', ale_py.__version__)

 env = gym.make("ALE/Breakout-v5", render_mode="rgb_array")

 play.play(env, zoom=3)

按
```
space
```
开始游戏和
```
s
```
和
```
d
```
来控制它。

享受...！

Answer 5

可以用conda解决：

安装健身房版本 0.19.0，由，

conda install -c conda-forge gym=0.19.0;

通过
安装atari_py
```
conda install -c conda-forge atari_py;
```
下载Roms，解压RAR.
打开一个终端，激活你的环境，然后输入：
```
python -m atari_py.import_roms \<path to folder\>, 
```
这将复制指定文件夹中的 ROM 到 pkg 文件夹。

Answer 6

即使使用较新的健身房也可以实现这一点（在我的例子中是 Windows 环境中的 0.24.0）。下载 ROM（通过 AutoROM）并通过 ale-import-roms 安装 ROM 后，您需要将环境变量 ALE_PY_ROM_DIR 设置为 bins 的目录。

在 python 中（在我的例子中是 Jupyter - 当然必须事先定义环境变量）你需要：

from ale_py import ALEInterface
ale = ALEInterface()

在此之后你可以（使用命名空间 ALE/）例如

from ale_py.roms import SpaceInvaders
ale.loadROM(SpaceInvaders)
env = gym.make('ALE/SpaceInvaders-v5')
