Cannot run script

~/dot-to-dot# python Main.py /root/photo_2020-05-28_23-40-58.jpg
Traceback (most recent call last):

File "/usr/local/lib/python2.7/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

How can I fix this?
