SuperMarioBros-Nes with OpenAI baseline, How?

本文主要是介绍SuperMarioBros-Nes with OpenAI baseline, How?，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

题意：SuperMarioBros-Nes 使用 OpenAI 基线，怎么做？

问题背景：

I am trying to run SuperMarioBros environment in OpenAI baselines. Usually these retro environments are different from native attari 2600 that been support by gym library.

我正在尝试在 OpenAI baselines 中运行 SuperMarioBros 环境。通常，这些复古环境与 gym 库支持的原生 Atari 2600 环境有所不同。

In order to make it run with baselines a third party library is need to be installed that comes with retro using the code taking the help from this link (How to setup Open AI Baselines + Retro - On Windows and Linux | videogames.ai)

为了使其与 baselines 一起运行，需要安装一个第三方库，该库附带在 retro 中，可以使用此链接中的代码进行设置（如何在 Windows 和 Linux 上设置 Open AI Baselines + Retro | videogames.ai）。

python -m retro.import .
python -m baselines.run --alg=a2c --env=SuperMarioBros-Nes --gamestate=Level3-1.state --network=cnn --num_env=2 --num_timesteps=1e3

but unfortunately even after this, it doesn't run and giving the error of rom not found.

但不幸的是，即使这样做了，仍然无法运行，并出现了“未找到 ROM”的错误。

Although after installing the external retro, it should be okay but its requiring raw-rom files directly from game-emulator. Is there any possible way to find a turn around ? Or am I missing something here

虽然在安装了外部的 retro 库后应该可以正常运行，但它仍然需要直接从游戏模拟器中获取原始 ROM 文件。有可能找到解决办法吗？还是我遗漏了什么？

    Process SpawnProcess-2: Traceback (most recent call last): 
File "/usr/local/lib/python3.6/dist-packages/retro/__init__.py", line 49, in make     retro.data.get_romfile_path(game, inttype)   
File "/usr/local/lib/python3.6/dist-packages/retro/data/__init__.py", line 288, in get_romfile_path    
raise FileNotFoundError("No romfiles found for game: %s" % game) FileNotFoundError: 
No romfiles found for game: SuperMarioBros-Nes

问题解决：

I did a hack and able to run the mario in retro (In windows itself). Below are step by step of the trick:

我做了一个小技巧，成功在 retro 中运行了马里奥（在 Windows 上）。以下是该技巧的步骤：

install retro and install gym-super-mario-bros · PyPI given in my previous answer

安装 retro 并安装 gym-super-mario-bros，链接在我之前的回答中提供。

Copy .nes files from lib/python3.7/site-packages/gym_super_mario_bros/_roms (this is where gym-super-mario-bros installed in site-packages) -> to Lib\site-packages\retro\data\stable\SuperMarioBros-Nes (This is where retro is installed in site-packages).

将 .nes 文件从 lib/python3.7/site-packages/gym_super_mario_bros/_roms（即 gym-super-mario-bros 安装在 site-packages 中的位置）复制到 Lib\site-packages\retro\data\stable\SuperMarioBros-Nes（即 retro 安装在 site-packages 中的位置）。

Rename the super-mario-bros.nes to rom.nes

将 super-mario-bros.nes 重命名为 rom.nes。

You are done. You can start mario using following code :

完成了。你可以使用以下代码启动马里奥：

import retro
def main():env = retro.make(game='SuperMarioBros-Nes')obs = env.reset()while True:obs, rew, done, info = env.step(env.action_space.sample())env.render()if done:obs = env.reset()env.close()if __name__ == "__main__":main()

An extra tip: If you want to play mario manually after this then run following command. (Z for jump and x for firing): python -m retro.examples.interactive --game SuperMarioBros-Nes [Enjoy]

额外提示：如果你想在此之后手动玩马里奥，可以运行以下命令。（Z 键跳跃，X 键开火）：python -m retro.examples.interactive --game SuperMarioBros-Nes [享受游戏]
