如何使用Google Colab安装vizdoom？

Question

I am following this tutorial using Google Colab. But I have problems with running from vizdoom import * that should enable the Doom environment. I tried to execute !pip install vizdoom , but it failed.

The instruction indicate that "You need to download vizdoom and place the folder in the repos". But it's unclear to me how to do it in Google Colab. Any help is highly appreciated.

You'll first need to install the vizdoom deps for Linux. They are listed on this page: 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

After installing these, I was able to import all the libraries successfully:

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

Here's a full example notebook: https://colab.research.google.com/drive/1zDRkLhgjfOzW9C8jCtQ7-99TPDhxpCev

The install takes ~10 minutes. You may want to consider using Colab with a local Jupyter runtime so that you can skip the setup overhead on subsequent invocations of your notebook.

In case you face with the following error

Simply run apt-get update before installing dependencies:

%%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
