Question

我设法在PyCharm项目中安装了OpenAI Gym Atari环境。（花了很多时间反复试验，我不知道是什么最终使它起作用。但是现在可以了。）

我复制了项目目录，从该副本创建了另一个项目，然后尝试运行之前运行的相同程序-实际上是我复制目录时创建的程序的副本。现在，我收到一条错误消息，提示未安装Atari环境-或未正确安装。

Traceback (most recent call last):
  File "C:\Users\rabbott\AppData\Local\Programs\Python\Python37\lib\site-packages\gym\envs\atari\atari_env.py", line 9, in <module>
    import atari_py
ModuleNotFoundError: No module named 'atari_py'

During handling of the above exception, another exception occurred:

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

Process finished with exit code 1

当我尝试再次安装它时，遇到了最初遇到的相同问题。特别是，我不知道如何正确安装Atari环境。

是否存在一些相对简单的方法来使用已在项目副本中运行的安装？

谢谢。

安装健身房和进行工作的最安全方法是使用python虚拟环境。为您的健身项目提供单独的虚拟环境总是更好。请使用conda或pipenv创建一个虚拟环境。

pipenv中的示例

安装pipenv

pip install --user pipenv

cd myproject

安装健身室

pipenv install gym

如下所示在您的虚拟环境中安装atari和任何其他依赖项。

pipenv install atari-py

运行您的代码

pipenv run python main.py

这将确保您的代码正常工作。

注意

Pipenv 为每个项目创建不同的虚拟环境。如果要对多个项目使用同一环境，请使用上述 conda 中的虚拟环境。

完全被PyCharm环境所迷惑
