Linux环境下Windows子系统运行vizdoom和pytorch程序时的多进程锁错误

Question

每当我试图在WSL上运行我的程序时，我会得到以下错误。我对火把和维兹厄姆非常陌生，所以我不知道如何解决这个问题。

设置

• Windows 10 x64
• Ubuntu 14 (关于WSL)
• Python 2.7.14 (Anaconda 2)
• OpenAI健身房0.9.5
• Vizdoom 1.1.4
• 厄运-py 0.0.14
• 帕奎特/健身房-厄运
• 放火枪0.0.12

gym.error.Error: [ViZDoomUnexpectedExitException, ViZDoomErrorException] VizDoom exited unexpectedly. This is likely caused by a missing multiprocessing lock. To run VizDoom across multiple processes, you need to pass a lock when you configure the env [e.g. env.configure(lock=my_multiprocessing_lock)], or create and close an env before starting your processes [e.g. env = gym.make("DoomBasic-v0"); env.close()] to cache a singleton lock in memory.

将WSL上的Ubuntu升级到最新版本(18.04)为我解决了这个问题。

对我来说，它是在WSL上运行以下命令。

sudo -S env RELEASE_UPGRADER_NO_SCREEN=1 do-release-upgrade
sudo apt-get update
sudo apt-get upgrade -y
