在适用于 Linux 的 Windows 子系统上运行 vizdoom 和 pytorch 程序时出现多处理锁定错误

Question

每当我尝试在 WSL 上运行我的程序时，都会收到以下错误。我对 pytorch 和 vizdoom 很陌生，所以我不知道如何解决这个问题。

安装程序
- Windows 10 x64- Ubuntu 14 (在 WSL 上(- Python 2.7.14 (Anaconda 2(

- OpenAI Gym 0.9.5
- Vizdoom 1.1.4
- doom-py 0.0.14

- ppaquette/gym-doom
- pytorch 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
