今天看到这个帖子 https://www.sunp.eu.org/t/356079 ，也想来试试手，对 Linux 完全新手，在 centos 上试装 opencv ，网上查了查：

yum localinstall ftp://fr2.rpmfind.net/linux/centos/7.3.1611/os/x86_64/Packages/opencv-2.4.5-3.el7.i686.rpm

然后就报错了： Loaded plugins: fastestmirror, priorities Setting up Local Package Process opencv-2.4.5-3.el7.i686.rpm | 3.9 MB 00:00
Examining /var/tmp/yum-root-SGWsb3/opencv-2.4.5-3.el7.i686.rpm: opencv-2.4.5-3.el7.i686 Marking /var/tmp/yum-root-SGWsb3/opencv-2.4.5-3.el7.i686.rpm as an update to opencv-2.0.0-12.el6.i686 Loading mirror speeds from cached hostfile epel/metalink | 20 kB 00:00

这个怎么办？求 V2er 们帮忙下，新手希望能解释详细点，先谢了:)
