When trying to import OpenCV, using import cv2
I get the following error:
/usr/local/lib/python2.7/dist-packages/cv2/__init__.py in <module>()
7
8 # make IDE's (PyCharm) autocompletion happy
----> 9 from .cv2 import *
10
11 # wildcard import above does not import "private" variables like __version__
ImportError: libSM.so.6: cannot open shared object file: No such file or directory
Not sure how to fix this - trying to play around with Google's new Colaboratory tool. Notebook is here: https://drive.google.com/file/d/0B7-sJqBiyjCcRmFkMzl6cy1iN0k/view?usp=sharing

This fixed the problem by having it as the first two lines of the script:
!pip install opencv-python
!apt update && apt install -y libsm6 libxext6

You need to add sudo . I did the following to get it installed :
sudo apt-get install libsm6 libxrender1 libfontconfig1
and then did that (optional! maybe you won't need it)
sudo python3 -m pip install opencv-contrib-python
FINALLY got it done !

For CentOS, run this:
sudo yum install libXext libSM libXrender

May be the problem is with your python-opencv
version. It's better to downgrade your version to 3.3.0.9 which does not include any GUI dependencies. Same question was found on GitHub here the link to the answer.
回答5:
There is now a headless version of opencv-python
which removes the graphical dependencies (like libSM). You can see the normal / headless version on the releases page (and the GitHub issue leading to this); just add -headless
when installing, e.g.,
pip install opencv-python-headless
# also contrib, if needed
pip install opencv-contrib-python-headless

I was facing similar issue with openCV on the python:3.7-slim
docker box. Following did the trick for me :
apt-get install build-essential libglib2.0-0 libsm6 libxext6 libxrender-dev
Please see if this helps !

I was not able to install cv2 on Anaconda-Jupyter notebook running on Ubuntu on Google Cloud Platform. But I found a way to do it as follows:
Run the following command from the ssh terminal and follow the instruction:
sudo apt-get install libsm6 libxrender1 libfontconfig1
Once its installed Open the Jupyter notebook and run following command:
!pip install opencv-contrib-python
Note: I tried to run this command: "sudo python3 -m pip install opencv-contrib-python"but it was showing an error. But above command worked for me.
Now refresh the notebook page and check whether it's installed or not by running import cv2
in the notebook.
