ImportError: libSM.so.6: cannot open shared object file: No such file or directory

在centos中使用opencv-python。在进行导入的时候报出如下错误

>>> import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/python3/lib/python3.6/site-packages/cv2/__init__.py", line 3, in <module>
from .cv2 import *
ImportError: libSM.so.6: cannot open shared object file: No such file or directory

主要原因时系统缺少libSM.so.6库文件。
可以使用如下命令查找包含此库的文件

yum whatprovides libSM.so.6


显示如下

Loaded plugins: fastestmirror, ovl
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
Determining fastest mirrors
* base: mirrors.bfsu.edu.cn
* epel: repo.ugm.ac.id
* extras: mirrors.bfsu.edu.cn
* updates: mirror.bit.edu.cn
libSM-1.2.2-2.el7.i686 : X.Org X11 SM runtime library
Repo : base
Matched from:
Provides : libSM.so.6

说明只要安装libSM-1.2.2-2.el7.i686文件就行
如果系统时64位需要把i686改成x86_64
如下

yum install libSM-1.2.2-2.el7.x86_64 --setopt=protected_multilib=false

如果缺少其他库一样方法安装就行。
