安装后没有名为“atari_py”的模块

Question

我目前正在尝试将 Atari 模块用于健身房/openai。我已成功安装依赖项。

Patricks-MacBook-Pro:~ patrickmaynard$ python3.6 -m pip install gym[atari]
Requirement already satisfied: gym[atari] in /usr/local/lib/python3.6/site-packages (0.10.5)

Requirement already satisfied: idna<2.7,>=2.5 in /usr/local/lib/python3.6/site-packages (from requests>=2.0->gym[atari]) (2.6)

但是，当我尝试运行该文件时，编译器找不到该模块，并且出现以下错误：

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/gym/envs/atari/atari_env.py", line 9, in <module>
    import atari_py
ModuleNotFoundError: No module named 'atari_py'

在处理上述异常的过程中，又发生了一个异常：

gym.error.DependencyNotInstalled: No module named 'atari_py'. (HINT: you can install Atari dependencies by running 'pip install gym[atari]'.)

gym 和 cmake 已经安装好了。

Answer 1

我想也许你在 pip 中安装了 atair，你可以尝试使用 pip3 安装。 python2中的importlib好像不兼容。

pip3 install atari-py

它对我有用:)

Answer 2

'atari_py' 在我的 pycharm IDE 中不起作用。尝试其他 IDE 或在终端/命令行中运行文件。

Answer 3

在 PyCharm IDE 中检查 atari_py 的版本，因为某些版本已被描述，因此它们不再工作或缺少文件 (ale_c.dll) 我在使用 Python 安装 atari_py 和 gym 时遇到了问题，因为我必须选择所有内容的正确版本才能正常工作。 Python atari_py 将运行的最高版本是 3.7（Python 3.7），就 atari_py 而言，我使用的是 0.2.6，因为我无法在更高版本上运行任何东西。 Gym 进口 atari_py (atari-py) 但正如我之前所说，它已被描述，因此最新版本的 Gym 0.21.0（0.20.0 和更高版本）使用 ale-py，它的工作方式略有不同，因为它表明你不做 env .render() 和游戏是 v5（v5 以下的所有内容都来自 atari_py）。遗憾的是，我无法让 Gym 0.21.0 和 ale-py 在单个游戏中正常工作，因为我发现的游戏的唯一示例是：

import gym

env = gym.make('ALE/Breakout-v5',
    obs_type='rgb',                   # ram | rgb | grayscale
    frameskip=5,                     # frame skip
    mode=0,                           # game mode, see Machado et al. 2018
    difficulty=0,                     # game difficulty, see Machado et al. 2018
    repeat_action_probability=0.25,   # Sticky action probability
    full_action_space=True,           # Use all actions
    render_mode=None                  # None | human | rgb_array
)

• 来自https://brosa.ca/blog/ale-release-v0.7，游戏无法正常运行。 （意思是在渲染游戏时，球不存在并且什么也没有发生——在低版本的游戏中看到了同样的问题，没有发生任何事情。）
