虚拟机安装不赘述了,使用版本为ubuntukylin-16.04-desktop-amd64(建议使用ubuntu而不是centos)。

安装过程很容易,按着顺序依次确定即可,安装完成之后需要进行网络配置,让我们的虚拟机链接上网络。

一、配置网络

1.打开VMware workstation ,菜单栏选项–>编辑–>虚拟网络编辑器,将VMnet8设置为NAT模式,启动DHCP(DHCP就是用来动态分配虚拟机IP的,不启用也没有关系), 如图:

2.在主机上开启NAT服务和DHCP服务

win+r –> services.msc

ubuntu的kylin16版本安装OpenAI gym

3.然后,打开VMware workstation ,菜单栏选项–>虚拟机–>设置为NAT模式

4.更改适配器设置,将可以上网的网络设置为共享,共享给虚拟机的VMnet8(不需要勾下面的勾):

二、配置Python3环境

ubuntu的kylin16系统自己带了Python2.7和Python3.5环境,我需要使用Python3.8+。

1.配置依赖环境,如果不进行这步可能会出现一些问题。

2.去官网下载Python-3.8.1.tar.xz

3.解压下载的包

tar -xvJf  Python-3.8.1.tar.xz

ubuntu的kylin16版本安装OpenAI gym

4.进入解压后的目录

cd Python-3.8.1/

5.安装依赖(非必要,可跳过此步骤,如在6步出错在执行本步骤)

执行下列命令安装依赖过程中,如有提示,一律y。

sudo apt-get install python-dev
sudo apt-get install libffi-dev
sudo apt-get install libssl-dev
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev

6.执行安装

./configure prefix=/usr/local/python3
sudo make && sudo make install

7.修改软连接(配置全局变量)

将原来的链接备份。

sudo mv /usr/bin/python /usr/bin/python.bak

添加python3的软链接。

sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python

测试是否安装成功了。

python -V

8.安装/升级pip

这句是给(python2.7安装pip)

sudo apt-get install python-pip

给python3安装pip。

sudo apt-get install python3-pip

执行升级。

sudo pip install --upgrade pip
sudo pip3 install --upgrade pip

升级pip时出现了问题:

Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main

修改一下pip配置

sudo vi /usr/bin/pip

改成

#原PIP配置文件
from pip import main  
if __name__ == '__main__':  
    sys.exit(main()) 

#修改为
from pip import __main__  //修改
if __name__ == '__main__':  
    sys.exit(__main__._main())//修改

9.pip3安装包时出现问题

Traceback (most recent call last):
  File "/usr/bin/pip3", line 11, in <module>
    sys.exit(main())
  File "/home/fulequn/.local/lib/python3.5/site-packages/pip/__init__.py", line 11, in main
    from pip._internal.utils.entrypoints import _wrapper
  File "/home/fulequn/.local/lib/python3.5/site-packages/pip/_internal/utils/entrypoints.py", line 4, in <module>
    from pip._internal.cli.main import main
  File "/home/fulequn/.local/lib/python3.5/site-packages/pip/_internal/cli/main.py", line 57
    sys.stderr.write(f"ERROR: {exc}")

原因

查了很多,大多数老外的说法是,高版本的pip不再支持python3.5

解决

移除pip的相关文件

sudo apt autoremove

下载pip的安装文件

url -O https://bootstrap.pypa.io/pip/3.5/get-pip.py

执行安装文件

/usr/bin/python3 get-pip.py

这句是给(python2.7安装pip)

sudo apt-get install python-pip

给python3安装pip。

sudo apt-get install python3-pip

pip升级

sudo pip install --upgrade pip
sudo pip3 install --upgrade pip

这个部分我卸载之后,出现了pip不存在的错误。之后重新安装,再升级就解决了。

三、安装OpenAI gym

输入下面语句,安装gym

pip install gym -i https://pypi.tuna.tsinghua.edu.cn/simple

1.出现下面错误

ModuleNotFoundError: No module named '_ctypes'

解决:

sudo apt install libffi-dev -y

2.出现错误

ERROR: No matching distribution found for gym[all]

3.出现错误
