Hi, I have just installed the latest release of graph-tool from anaconda. I
would like to use your /graph_draw/ method to visualise graph but it fails
to import the cairo_draw module.
*from graph_tool.draw import cairo_draw*

My environment:
============
Ubuntu 18.04 (bionic)
Anaconda3-2019.07-Linux-x86_64
Python 3.7.4
I have created my virtual environment and installed graph_tool with
conda install -c conda-forge graph-tool
graph-tool 2.29
The package has been successfully installed under
~/anaconda3/envs/TRIADB/lib/python3.7/site-packages
and I have also tried to set LD_LIBRARY_PATH to solve the Imp ortError above
echo $LD_LIBRARY_PATH
/home/athan/anaconda3/envs/TRIADB/lib:/home/athan/anaconda3/envs/TRIADB/lib/python3.7/site-packages/graph_tool:
Unfortunately this did not work, is there anything else I can try to enable
drawing methods ?
Thank you in advance for your time to answer my question and kudos for
sharing this excellent code, graph network library with the rest of us.
