在docker虚拟机下安装了opencv以后，在使用的时候出现以下报错，

Traceback (most recent call last):
  File "data_generator.py", line 24, in
    import cv2
  File "/usr/local/lib/python3.5/dist-packages/cv2/__init__.py", line 3, in
    from .cv2 import *
ImportError: libSM.so.6: cannot open shared object file: No such file or directory

原因是缺少共享文件库，有两种解决办法：

试了下，这两种方法均不适合自己情况，遂采用第三种办法。
参考 https://blog.csdn.net/quincuntial/article/details/79047050
先安装apt-file。

# Install
$ apt-get update
$ apt-get install apt-file
# Update apt-file
$ apt-file update

然后寻找该依赖库：

apt-file search libSM.so.6

根据提示安装合适的依赖库：

 

apt-get install libsm6 即可解决问题。
