在ubuntu14.04和16.04上配置caffe有很多坑，主要就是解決lib依賴庫的問題，因為有好多包都不是最新的，不是一次update就可以解決的，本人linux安裝過3個版本的14.04，16.04，18.04，其中18.04安裝caffe最簡單，一次過，安裝包去官網下載即可。

編輯/etc/apt/sources.list檔案, 在檔案最前面新增以下條目(操作前請做好相應備份)：

##中科大源

deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

1.      Ubuntu18.04更換國內源。經過多次實驗，發現目前中科大的源最好。

a)    備份原始檔。

cd /etc/apt

sudo cpsources.list sources.list.backup

b)    更改中科大的源。

debhttps://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse

deb-srchttps://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse

debhttps://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universemultiverse

deb-srchttps://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universemultiverse

debhttps://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universemultiverse

deb-srchttps://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universemultiverse

debhttps://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universemultiverse

deb-srchttps://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universemultiverse

debhttps://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universemultiverse

deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposedmain restricted universe multiverse

c)    執行命令，更新軟體。（這時候會提示有兩個軟體無權訪問的錯誤，我無視了）

sudo apt-get update

sudo apt-get upgrade

2.      安裝caffe（cpu）

sudo apt install caffe-cpu

3.      Caffe 預設呼叫是python3.6.5

4.      enjoy it！
