搭建gym環境

之前已經安裝過Anaconda和Git 所以跳過了教程安裝Anaconda和Git的步驟

照書上折騰了半天，發現官網安裝方法比較簡單，安好了就不刪了重弄了(Gym官網)

首先在CMD下輸入命令

conda create --name gymlab python=3.6

安裝的過程如下

C:\WINDOWS\system32>conda create --name gymlab python=3.6

  environment location: C:\Users\MDD\AppData\Local\Continuum\anaconda3\envs\gymlab

  added / updated specs:
    - python=3.6


The following packages will be downloaded:

然後在python工作目錄clone gym包

git clone https://github.com/openai/gym.git

過程如下

git clone https://github.com/openai/gym.git

安裝

pip install –e ‘.[all]’

按照教程安裝gym報錯一堆- -，提示使用如下命令

python -m pip install --upgrade pip

emmm，女朋友搶網，不小心升級一半取消了，解除安裝了pip…*（用pip解除安裝了pip，哎）
搜尋教程，重灌一下pip…

python -m pip uninstall pip
easy_install.exe pip

提示無效的命令 -e…頭疼

Invalid requirement: '–e'

emmm，原來是複製pdf書上的命令有問題，看了Git上的說明，應該是

pip install -e .

安裝過程報了2個錯誤

pip install -e .

應該是說了2個不相容，pommerman0.2.0這個環境需要的環境，其中flask應該為0.12我的是1.0.2不相容，pylint應該是1.9.2，我的是1.8.4，先跳過把，一會看這兩個包，剩下的應該安裝成功了。
