关于配置网络以及安装库的解决方法

2018-03-06

先安装python
Ctrl+Alt+T打开终端,依次输入以下命令:
sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python
sudo apt-get install libncurses5-dev

鉴于有些同学安装不上pip,我们可以尝试修改apt-get的代理
首先,打开文件sources.list,弹出窗口如下,选择添加

之后,再按Ctrl+Alt+T打开终端顺序执行以下命令:

sudo apt-get update

sudo apt-get upgrade
sudo apt-get python-pip
检验pip是否安装成功为输入pip -V
出现一下信息为安装成功(pip版本可能略有不同)
1
pip 9.0.1 from /home/figo/.local/lib/python2.7/site-packages (python 2.7)

如果以上方法不起作用,这里还有一个备用方法

首先,Ctrl+Alt+T进入终端

之后,输入sudo gedit /etc/apt/sources.list

将其中的内容替换为:


deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse

替换完之后重启电脑,执行之前安装pip的代码

接下来安装numpy与pyevolve

终端命令:
pip install numpy
pip install pyevolve

安装成功了pyevolve之后就可以愉快地使用遗传算法了
