Hi again, I installed pycairo=1.10.0 again and reinstall graph-tool. Now I do not get the error message I posted in my previous email but I get the new one. The following error:

...

...

import graph_tool from graph_tool.all import * Gtk-Message: 18:16:20.063: Failed to load module "canberra-gtk-module" Gtk-Message: 18:16:20.067: Failed to load module "canberra-gtk-module" import matplotlib.pyplot as plt g = Graph() v1 = g.add_vertex() v2 = g.add_vertex() e = g.add_edge(v1, v2) graph_draw(g, vertex_text=g.vertex_index, vertex_font_size=18,output_size=(200, 200)) Segmentation fault (core dumped)

I can see that I have gtk3 installed but I can not understand why it can not be loaded? Any suggestion how to solve all these errors? Cheers, Zahra On Tue, Jul 10, 2018 at 4:12 PM, Zahra Sheikhbahaee <zsheikh2017@gmail.com> wrote:

Hi Tiago,

I have been using channel "ostrokach-forge" to even install properly version 2.26 on a server and it constantly get error messages for its dependencies. I have used conda to install the dependencies but now I get this error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/anaconda3/lib/python3.5/site-packages/graph_tool/all.py", line 35, in <module> from graph_tool.draw import * File "/home/anaconda3/lib/python3.5/site-packages/graph_tool/draw/__init__.py", line 875, in <module> from .cairo_draw import graph_draw, cairo_draw, get_hierarchy_control_points, default_cm File "/home/anaconda3/lib/python3.5/site-packages/graph_tool/draw/cairo_draw.py", line 122, in <module> "font_slant": cairo.FONT_SLANT_NORMAL, AttributeError: module 'cairo' has no attribute 'FONT_SLANT_NORMAL'

Do you have any suggestion how to solve this error message?

I installed cairocffi, cairo, pycairo but apparently none of them solve this error message.

Thanks in advance.

Best, Zahra

Hi Zahra,

I'm not responsible for any anaconda package of graph-tool. They were made by third parties, and you need to contact them and ask them to update to the newest version.

Best, Tiago

Hi Tiago,

I am trying to install graph-tool on a server and the only way it is possible without root permission is via this command line:

conda install -c ostrokach-forge graph-tool

But its version is

...

...

...

graph_tool.__version__ '2.25 (commit , )'

well, how could I update this version in the conda environment to 2.27?

Thanks, Zahra
