如何使用 Google Colab 安装 vizdoom？

我正在关注本教程 https://github.com/simoninithomas/Deep_reinforcement_learning_Course/blob/master/Policy%20Gradients/Doom/Doom%20REINFORCE%20Monte%20Carlo%20Policy%20gradients.ipynb使用谷歌Colab。但我跑步时遇到问题from vizdoom import *这应该启用 Doom 环境。 我尝试执行!pip install vizdoom，但失败了。

该指令表明“您需要下载 vizdoom 并将该文件夹放入存储库中”。但我不清楚如何在 Google Colab 中做到这一点。 非常感谢任何帮助。

您首先需要安装适用于 Linux 的 vizdoom deps。它们列在此页面上：https://github.com/mwydmuch/ViZDoom/blob/master/doc/Building.md#-linux https://github.com/mwydmuch/ViZDoom/blob/master/doc/Building.md#-linux

%%bash
# Install deps from 
# https://github.com/mwydmuch/ViZDoom/blob/master/doc/Building.md#-linux

apt-get install build-essential zlib1g-dev libsdl2-dev libjpeg-dev \
nasm tar libbz2-dev libgtk2.0-dev cmake git libfluidsynth-dev libgme-dev \
libopenal-dev timidity libwildmidi-dev unzip

# Boost libraries
apt-get install libboost-all-dev

# Lua binding dependencies
apt-get install liblua5.1-dev

安装这些后，我能够成功导入所有库：

import tensorflow as tf      # Deep Learning library
import numpy as np           # Handle matrices
from vizdoom import *        # Doom Environment
import random                # Handling random number generation
import time                  # Handling time calculation
from skimage import transform# Help us to preprocess the frames

from collections import deque# Ordered collection with ends
import matplotlib.pyplot as plt # Display graphs

这是一个完整的示例笔记本：https://colab.research.google.com/drive/1zDRkLhgjfOzW9C8jCtQ7-99TPDhxpCev https://colab.research.google.com/drive/1zDRkLhgjfOzW9C8jCtQ7-99TPDhxpCev

安装大约需要 10 分钟。您可能需要考虑使用 Colab本地 Jupyter 运行时 http://research.google.com/colaboratory/local-runtimes.html这样您就可以在后续调用笔记本时跳过设置开销。
