学习deepmind lab 前期准备工作

安装构建工具bazel

sudo apt-get install openjdk-8-jdk

echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list

curl https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -

sudo apt-get update && sudo apt-get install bazel

sudo apt-get upgrade bazel

下载deepmind lab

$ git clone https://github.com/deepmind/lab[/code] 
$ cd lab


安装依赖，编译，执行一个例子
更多的例子参考deepmind lab官网

$ sudo apt-get install lua5.1 liblua5.1-0-dev libffi-dev gettext \ freeglut3-dev libsdl2-dev libosmesa6-dev python-dev python-numpy realpath


$ bazel build :deepmind_lab.so --define headless=glx


$ bazel run :game -- --level_script tests/demo_map


bazel工程文件简单介绍
工程的构建工具是bazel，工程结构符合bazel规则，WORKSPACE文件标识工作区；BUILD文件标识包，其中的文件表名了各文件之间的依赖关系；编译后生成的执行文件位于bazel-bin中，结果如图1。具体的bazel规格参考bazel官网


官方例子
bazel run :game -- --level_script tests/demo_map
这个例子执行了bazel-bin下面的game程序，加载的地图为demo_map,game的源码为lab下examples/game_main.c，地图资源为lab下/assets/game_scripts/tests/demo_map.lua
