如何使用 Google Colab 安装 vizdoom？

Question

我正在使用 Google Colab 关注 this tutorial。但是我遇到了运行 from vizdoom import * 应该启用 Doom 环境的问题。我尝试执行 !pip install vizdoom，但它失败了。

指令表明"You need to download vizdoom and place the folder in the repos"。但我不清楚如何在 Google Colab 中执行此操作。非常感谢任何帮助。

您首先需要为 Linux 安装 vizdoom deps。它们列在此页面上： 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

安装大约需要 10 分钟。您可能需要考虑将 Colab 与 a local Jupyter runtime 结合使用，这样您就可以跳过后续调用笔记本的设置开销。

如果您遇到以下错误

只需运行apt-get更新再安装依赖：

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

apt-get update

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
