    教你从头到尾利用DQN自动玩flappy bird(全程命令提示、纯小白教程)



作者:骁哲、李伟、July
说明:本教程主要由骁哲编写,且最后跑的是yenchenlin的github开源demo。如遇问题欢迎加Q群交流:472899334。
时间:二零一六年十月十三日。



前言

    我们在上一篇教程《基于torch学汪峰写歌词、聊天机器人、图像着色/生成、看图说话、字幕生成》中说到:“让每一个人都能玩一把,无限降低初学朋友的实验门槛”,那是否能把难度再次降低呢,比如部分同学不熟悉Linux命令咋整,那是不是不熟悉Linux命令就没法折腾了?然既然是为了让每个人都能玩一把,那就应该尽最大可能照顾到最大多数。

    本教程提供全程命令提示,以便让Linux命令暂不熟的同学也能搭建起来。因此,自动玩转flappy bird分三个步骤:

  1. 不管三七二十一,先把游戏搭建起来
  2. 搭建起来后,Linux命令后续慢慢熟悉,熟悉后,一通百通,搭建其他实验的环境也会立马顺畅许多
  3. 取得成就感和安心之后,再细细深究实验背后之原理(另,10月机器学习算法班上也会深究实验背后原理)

   另本教程省略了ubuntu14.04安装,如果此前没安装过Ubuntu,可以参看《教你从头到尾利用DL学梵高作画》里的第4.1部分。

   还是这个事,欢迎更多朋友跟我们一起做实验,一起玩。包括本flappy bird在内的8个实验:梵高作画、文字生成、自动聊天机器人、图像着色、图像生成、看图说话、字幕生成、flappy bird,10月份内做出这8个实验中的任意一个并在微博上AT@研究者July,便送100上课券,把实验心得发社区 ask.julyed.com 后,再送100上课券。



一、NVIDIA驱动、CUDAcudnn安装

 apt-get update (更新源)

apt-get install vim (安装VIM

vi /etc/default/grub (进入grub文件)

添加text (具体方法参看《教你从头到尾利用DL学梵高作画》

update-grub2 (更新一下)

reboot (重启)

2、 Install CUDA 安装CUDA

  cd /**/**/** (cdcuda所在文件目录下)

  ./cuda_8.0.27_linux.run  (安装CUDA

  accept之后第一个选项填写“n”(该选项让你选择是否安装NVIDIADriver,之前已经安装过了,  所以不需要),之后一路“绿灯”。

vi /etc/default/grub    (打开grub

修改text (具体方法参看《教你从头到尾利用DL学梵高作画》

update-grub2 (更新一下)

reboot (重启)

3、 Install cuDNN 安装cuDNN

Please specify the location of python. [Default is /usr/bin/python]:

Do you wish to build TensorFlow with Google Cloud Platform support? [y/N] N

No Google Cloud Platform support will be enabled for TensorFlow

Do you wish to build TensorFlow with GPU support? [y/N] y

GPU support will be enabled for TensorFlow

Please specify which gcc nvcc should use as the host compiler. [Default is /usr/bin/gcc]:

Please specify the Cuda SDK version you want to use, e.g. 7.0. [Leave empty to use system default]: 8.0

[Default is: "3.5,5.2"]: 

Setting up Cuda include

Setting up Cuda lib

Setting up Cuda bin

Setting up Cuda nvvm

Setting up CUPTI include

Setting up CUPTI lib64

Configuration finished

3、 Create the pip package and install    创建pip包并且安装

  bazel build -c opt //tensorflow/tools/pip_package:build_pip_package  (笔者用公司网提示error,翻墙后问题解决)

  bazel build -c opt --config=cuda //tensorflow/tools/pip_package:build_pip_package

  bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg(笔者安装过程中出现ImportErrorNo module named setuptools,解决办法:apt-get install python-pip,安装python-pip就行了)

  sudo pip install /tmp/tensorflow_pkg/tensorflow-0.11.0rc0-py2-none-any.whl

4、 Setting up TensorFlow for Development    编译设置Tensorflow

  bazel build -c opt //tensorflow/tools/pip_package:build_pip_package

  bazel build -c opt --config=cuda //tensorflow/tools/pip_package:build_pip_package

  mkdir _python_build

  cd _python_build

  ln -s ../bazel-bin/tensorflow/tools/pip_package/build_pip_package.runfiles/org_tensorflow/* .

  ln -s ../tensorflow/tools/pip_package/* .

  python setup.py develop

5、 Train your first TensorFlow neural net model    测试Tensorflow

  cd tensorflow/models/image/mnist

  export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/extras/CUPTI/lib64"

  export CUDA_HOME=/usr/local/cuda (这里重新添加环境变量是因为笔者安装过程中提示未能找到CUDA

  python convolutional.py(笔者这里出现AttributeErrortype object ‘NewBase‘ has no attribute ‘is_abstract‘问题,解决办法:sudo pip install six --upgrade -- target="/usr/lib/python2.7/dist-packages"

 


三、 安装OpenCV

Download OpenCV    下载OpenCV

  浏览器打开  http://opencv.org/

  右侧下载Linux版本的OpenCV

  cd到下载目录

  unzip opencv-2.4.13.zip

  cd opencv-2.4.13

  mkdir release  

  sudo apt-get install build-essential cmake libgtk2.0-dev pkg-config python-dev python-numpy libavcodec-dev libavformat-dev libswscale-dev  

  cd release  

  cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..  

  sudo make install

  cd pygame-1.9.1release

  python config.py

run deep_q_network.py

  python  deep_q_network.py        运行deep_q_network.py  (笔者这里报错:AttributeError:‘module‘ object has no attribute ‘stack‘,解决办法:

sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas  

python-sympy python-nose

git clone git://github.com/numpy/numpy.git numpy  (笔者这里运行了一下cd numpypython setup.py install,发现报 

错缺少cython于是执行后面的命令)

apt-get install cython

cd numpy

python setup.py install



六、 执行程序

    全部安装完后,再次执行

  python  deep_q_network.py

    画面卡住等待一下,GPUCUDA在运行需要时间..

    稍等片刻,奇迹出现了,飞鸟开始自动飞、自动上下跳跃、自动穿过障碍,要知道纯人工手动玩很难坚持9s!
