九章算法 - 强化学习 - 实战项目2

安装过程

  1. 确认已经安装conda, 安装详情请参考之前的教程:https://www.jiuzhang.com/tutorial/ai-camp/477

  2. 打开一个terminal,windows用户建议打开Anaconda Prompt.

  3. 输入命令行: conda create --name rl_p2 python=3.5

  4. 输入命令行: conda activate rl_p2
    如果激活环境遇到了问题,conda会自己提示解决方案,比如:
    、、、 CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'. If your shell is Bash or a Bourne variant, enable conda for the current user with

    $ echo ". /Users/Andrew/anaconda3/etc/profile.d/conda.sh" >> ~/.bash_profile 、、、
    NOTE: 注意Andrew是我的用户名,请根据自己的提示信息进行修改

  5. 输入命令行: git clone https://github.com/jiuzhangjiangzuo/reinforcement_learning_p2.git 或直接下载压缩包link

  6. 输入命令行: cd reinforcement_learning_p2

  7. 输入命令行: pip install -r requirements.txt

  8. 输入命令行: pip install gym[atari]

  9. 安装ffmpeg库
    Mac OS - 输入命令行: brew install ffmpeg
    如果Mac OS系统上没有安装brew,请先运行以下命令(参考brew官网):
    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    Linux - 输入命令行: sudo apt-get install ffmpeg
    Windows: 请尝试按照官网的说明安装: https://www.ffmpeg.org/download.html

  10. 测试是否可以运行: python dqn_atari.py
    Note: 如果看到一下这个错误,说明环境是没有问题的,这个错误是因为模型部分还没有实现引起的。

ValueError: ('Expected `model` argument to be a `Model` instance, got ', None)
