python - 如何修复 open-ai 健身房中的环境错误？

问题描述

代码：

import gym
env = gym.make('Breakout-v0')

我收到一个错误：

解决方案

我试图让它在 Windows 10 上与 python 3.8 和 3.9 一起工作。安装 Python 3.7 并将其用作 PyCharm 上的 Python 解释器解决了这个问题。我在拥有 3.8 + 版本的 Python 时搜索了丢失的文件，但它根本不存在。仅 Python 3.7 ( https://github.com/openai/atari-py ) 支持 Atari-py，因此使用更高版本将无法正常工作。从未经许可的地方下载文件是个坏主意，因此我建议您安装受支持的 Python 版本（3.5、3.6 和 3.7）。即使gym可以在3.9上运行，但atari版本却不行。我不需要安装任何其他东西（虽然我可能有Microsoft Visual C++ Build Tools，但我deff不需要Xming），只需导入gym 0.18.0，pyglet 1.5.0，atari -py 0.2.6
