我对 OpenAi 健身房完全陌生，我刚刚安装了健身房，然后尝试为 env = gym.make('MsPacman-v0') 所以我收到以下错误：

---------------------------------------------------------------------------

 21     return path
 22 

Exception: ROM is missing for ms_pacman,see https://github.com/openai/atari-py#roms for instructions

此后我也尝试在网上找到解决方案并下载ROMs然后点击命令python -m atari_py.import_roms <path where ROMs downloaded>，运行此命令后我也收到以下错误

(env_project) C:\Users\ME>python -m atari_py.import_roms C:\Users\ME\Downloads\roms_folder\

我不知道我做错了什么。提前致谢。

解决方法

下载 ROMs 后，它将在 Downloads 文件夹中以 Roms.rar 的形式提供，它在 HC ROMS.zip 和 ROMS.zip 中包含 2 个 zip 文件，我必须解压 Roms.rar再次提取ROMS.zip。然后运行命令。

python -m atari_py.import_roms C:\Users\ME\Downloads\Roms\ROMS

,

此脚本应该可以解决问题

import urllib.request
urllib.request.urlretrieve('http://www.atarimania.com/roms/Roms.rar','Roms.rar')
!pip install unrar
!unrar x Roms.rar
!mkdir rars
!mv HC\ ROMS.zip   rars
!mv ROMS.zip  rars
!python -m atari_py.import_roms rars
