I am playing around with using python iGraph for network visualization. I got his error message when I tried to plot a graph:
>>> layout = g.layout("kk")
>>> plot(g, layout = layout)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

I don't think I installed Cairo or PyCairo correctly.
I am not familiar using Fink or MacPorts, since I commonly use Homebrew.
Any help you be greatly appreciated.
You need to manually compile the library. I used the solution here and just updated the version.
curl -L https://www.cairographics.org/releases/cairo-1.14.6.tar.xz -o cairo.tar.xz
tar -xf cairo.tar.xz && cd cairo-1.14.6
./configure --prefix=/usr/local --disable-dependency-tracking
make install
If while running configure, you get an error about pkg_config, you can install that with brew:
brew install pkg-config
I had the same problem on my MacBook so I wanted to share my solution.
I tried to install pycairo, py2cairo. The installation seemed to be okay but then:
I could not import pycairo
igraph's plot would not work.
The following solved the igraph plotting issue:
sudo pip install cairocffi
or just
pip install cairocffi
So instead of pycairo I used cairocffi and this did the trick.
As Mads said in a comment, brew install cairo works, it solved a related problem for me, so I'm posting here for people who end up here why troubleshooting cairo on OS X.
Accepted answer lead to an error of libpng missing, homebrew on the other hand installed all dependencies correctly.

I have this setup:
$ python -V
Python 2.7.2+
$ python -c "import pygame; print pygame.__version__"
1.9.1release
When I run a pygame script, I get this error:
Traceback (most recent call last):
File "/home/santosh/tmp/pygameHelloWorld.py", line 8, in <module>
windowSurface = pygame.display.set_mode((500, 400), 0, 32)
pygame.error: No available video device
I am using Ubuntu and have install pygame with apt-get. Additionally I have install all dependencies mentioned on this pygame wiki page.
If you are running Pygame on a UNIX system, like a Linux server, try using a DummyVideoDriver:
import os
os.environ["SDL_VIDEODRIVER"] = "dummy"
From similar experience the most likely problem is something is wrong with one of your SDL packages. Try running the following.
import pygame
pygame.init()
pygame.display.list_modes()
If you get back an empty list, it's definitely because of the packages. Try reinstalling them.
Possibly related:
SDL init failure, reason is: No available video device
SDL init failure, reason is: No available video device in ubuntu 12.04 LTS
This problem might only affect Windows XP. Try adding one of these to your code:
import os
os.environ['SDL_VIDEODRIVER']='windib'
or
import os
os.environ['SDL_VIDEODRIVER']='windlib'
Good luck.
Wild guess - is the DISPLAY environment variable set and/or required by the library, and not available? This could be the case if you're ssh-ing into the Linux machine you're running this on without providing the -X option.
Try the following:
import pygame
from pygame.locals import *
pygame.init()
On Linux you can solve the problem using x11.
Verify that your SDL was built with x11 support, otherwise build it yourself only after that you added some libraries in this way:
sudo apt install xorg-dev libx11-dev libgl1-mesa-glx
Maybe xorg-dev already installs libx11-dev
Build SDL from source and enjoy
I solved it with the three commands below:
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install libsdl1.2debian:i386
I was getting this error while trying to render an OpenAI gym in a jupyter notebook. Following fushan's answer got it to stop erroring, but it only rendered a black image. Looking at https://wiki.libsdl.org/FAQUsingSDL, I figured out that I could use directfb as the renderer. The code ended up being:
import os
os.environ["SDL_VIDEODRIVER"] = "directfb"
I'm using Ubuntu 20.04.1 LTS. I have installed pygame with sudo apt-get install python-pygame. However, when I run my code using VS code, the python terminal gives the output below:
Traceback (most recent call last):
File "path", line 1, in <module>
import pygame
ModuleNotFoundError: No module named 'pygame'
I tried to reinstall Pygame using the same command. Here is the output:

python-pygame is already the newest version (1.9.6+dfsg-2build1).
0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.
Basically, I already have pygame installed. So what do you think might be the reason? My Python version is 3.8.2.
Thanks in advance!
There isn't a release build of pygame 1.9.6 for Python 3.8.2. Install a development version:
python3 -m pip install pygame==2.0.0.dev10
My VM is using Ubuntu 14.04.
I followed the official manual to install MySql Fabric:
First, install Connector/Python GA
Next, install MySQL Utilities 1.5.6
However, when I tried to test the mysqlfabric help command, it threw error like:
Traceback (most recent call last):
File "/usr/bin/mysqlfabric", line 33, in <module>
from mysql.fabric import (
ImportError: No module named fabric
Based on this SO question, after upgrading Ubuntu from 15.04, the problem can be resolved, but I want to run fabric on Ubuntu 14.04.
I tried to re-installed Connector/Python, MySQL Utilities, also checked compatibility with Ubuntu version 14.04, searched on the Internet & SO for similar problems. But still cannot resolve the issue.
Thanks a lot for your help!
Not quite sure what is the problem with installing using .deb file.
But after many (painful) tries, I figured out that re-installing MySQL Utilities from source code can resolve the issue.
i try to install pygobject for python 3 in fedora 18
i read this doc https://python-gtk-3-tutorial.readthedocs.org/en/latest/install.html and i try to install jhbuild after that when i type $ jhbuild sanitycheck
get this error : bash: jhbuild: command not found...
i try to install with yum , i install "pygobject3-devel" but this not work with python3
in fedora 18 default python is python2.7.3, i install python3.3.0 with yum and test a first demo code :
#!/usr/bin/python
from gi.repository import Gtk
win = Gtk.Window()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
after give chmod +x for this python file can run with this command "./test.py"
and if i try to run with python (with out use #! ....) and type this command "$python test.py" that run and work without any problem but when i type this command "$python3 test.py" i get this error :
Traceback (most recent call last):
File "test.py", line 2, in <module>
from gi.repository import Gtk
ImportError: No module named 'gi'
have any idea ?
thanks
Try installing pygobject3 instead of pygobject3-dev (as a matter of fact, it seems that pygobject3 is already installed in a vainilla installation of Fedora).
After installing that package, you should be able to open your interpreter (python2.7) and do:
from gi.repository import Gtk
If you want to use python3 (I didn't understand if you meant that you tried to use python3 or you want to use python3), it seems that the gnome instrospection bindings are not yet available, according to this page that summarizes the state of different packages python3-related that are being on the works.
EDIT: I just tried installing python3-gobject (which should be installed when installing pygobject3, but it doesn't for some reason) and it seems to be working aswell on python3.
I am trying to install MySQLdb python and am having trouble getting it to work because I get an architecture error.
>>> import MySQLdb
Traceback (most recent call last):

/Users/jkeesh/.python-eggs/MySQL_python-1.2.3-py2.6-macosx-10.6-x86_64.egg-tmp/_mysql.so: mach-o, but wrong architecture
This has been a common question, and I have read many, many sources including:
Python MySQL wrong architecture error
http://www.mechanicalgirl.com/view/installing-django-with-mysql-on-mac-os-x/
Django + MySQL on Mac OS 10.6.2 Snow Leopard
Installing MySQLdb on Mac OS X
and many other links.
It appears that the problem is a 32-bit 64-bit mismatch, but I'm not sure what the right combination is, or what exactly the mismatch is.
I have installed from pip, from Mac ports, and built from the source. I have tried setting the ARCHFLAGS to both i386 and and x86_64.
I have tried setting VERSIONER_PYTHON_PREFER_32_BIT and VERSIONER_PYTHON_PREFER_64_BIT preferences.
I am running Mac OS X 10.6.6
I have mysql installed in /usr/local/mysql
$ file $(which ./mysql)
./mysql: Mach-O executable i386
I have mysql version 5.5.12
I have 64 bit Python 2.6.6.
My system architecture is:
>>> platform.platform()
'Darwin-10.6.0-i386-64bit'
$ file $(which python)
/opt/local/bin/python: Mach-O 64-bit executable x86_64
If there are any links you can point me to or suggestions to try I would really appreciate it. I'm kind of at a dead end and getting the same "wrong architecture" error no matter what I try.
Try to add this in your .bashrc or .bash_profile:
PATH="/usr/local/mysql/bin:${PATH}"
export PATH
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
export VERSIONER_PYTHON_PREFER_64_BIT=no
export VERSIONER_PYTHON_PREFER_32_BIT=yes
I've solved my own question, so hopefully this can be of help to people with similar issues.
I believe I had a 32-bit mysql installation.
I uninstalled all versions of mysql that I had
I went back and installed mysql 5.1 from the source, but I think a mysql 5.1 x86_64 bit dmg or binary would work also.
I used this make command from this post http://hivelogic.com/articles/compiling-mysql-on-snow-leopard/
I had permission issues and finally got it working using
sudo mysqld_safe --skip-grant-tables &
I installed MySQL-python 1.2.3c1 from here
