ImportError: libSM.so.6: cannot open shared object file: No such file or directory
Question:
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
Answers:
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
!apt-get install -y libxrender-dev
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.
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 !
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.
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 had the same problem in docker and these steps worked for me:
apt update
then:
apt install libsm6 libxext6 libxrender-dev
I got the same error using heroku, follow these steps:
add a file named Aptfile in your repo
and include a list of apt package names to be installed in that Aptfile
something like this in (my case)
libsm6
libxrender1
libfontconfig1
libice6
now try pushing the code to heroku. This will do the job.
