Re: [igraph] igraph for python plotting using pycairo on mac OScatalina (10.15.4)
thank you all. the best way to install python-igraph with all dependencies is to use anaconda. "conda install -c conda-forge python-igraph". that solved plotting issues. best. sid On Mon, Mar 30, 2020 at 4:05 AM Szabolcs Horvát wrote: > For readers who are not aware, this question was cross-posted (and > answered) at: > > > https://igraph.discourse.group/t/igraph-for-python3-plotting-using-pycairo-on-mac-oscatalina-10-15-4/162 > > Please use https://igraph.discourse.group/ for future questions. > > On Mon, 30 Mar 2020 at 09:59, serafim loukas wrote: > >> Hi Sid, >> >> Have a look here: https://stackoverflow.com/a/45416251/5025009 >> >> Makis >> >> On 30 Mar 2020, at 09:56, Tamas Nepusz wrote: >> >> import pycairo from >> >> >> ___ >> igraph-help mailing list >> igraph-help@nongnu.org >> https://lists.nongnu.org/mailman/listinfo/igraph-help >> > ___ > igraph-help mailing list > igraph-help@nongnu.org > https://lists.nongnu.org/mailman/listinfo/igraph-help > ___ igraph-help mailing list igraph-help@nongnu.org https://lists.nongnu.org/mailman/listinfo/igraph-help

Re: [igraph] igraph for python plotting using pycairo on mac OScatalina (10.15.4)
Hi,
python-igraph simply tries to import pycairo or cairocffi when it
initializes the plotting module. If the import fails, it simply throws a
"plotting not available" exception for all plotting attempts. So, to figure
out what's wrong, try to import pycairo from the same Python session where
you see this error -- this should give you a hint about what's wrong. Most
likely pycairo is not installed correctly.

[igraph] igraph for python plotting using pycairo on mac OScatalina (10.15.4)
Hi Group: I would appreciate if someone can help regarding whak cairo to
install and how to run with python3. I have successfully installed
python-igraph and everything works fine. However, as suggested, I installed
cairo (from Apple App), that didn't work, so I installed pycairo as
suggested in
https://stackoverflow.com/questions/36225410/installing-cairo-and-pycairo-mac-osx
However, I am still getting error-
import igraph
from igraph import *
g = Graph([(0,1), (0,2), (2,3), (3,4), (4,2), (2,5), (5,0), (6,3), (5,6)])
layout = g.layout("kk")
plot(g, layout = layout)
I get the following error:
TypeError Traceback (most recent call
last) in () 7
print(g.degree()) 8 layout = g.layout("kk")> 9 plot(g, layout
= layout)
~/anaconda3/lib/python3.6/site-packages/igraph/drawing/__init__.py in
plot(obj, target, bbox, *args, **kwds)453 bbox =
BoundingBox(bbox)454 --> 455 result = Plot(target, bbox,
background=kwds.get("background", "white"))456 457 if
"margin" in kwds:
~/anaconda3/lib/python3.6/site-packages/igraph/drawing/__init__.py in
__init__(self, target, bbox, palette, background)118 """

TypeError: plotting not available
