pyviz doesn't work under ns3.30 ubuntu 18.04

[fatima zahra rabahi]

I installed the ns3.30 under ubuntu 18.04 but I could not install pyvis for visualized the topology of my network?
I will always have this mistake;
E: Can not find python-pygoocanvas package

How do I do ?

[Jay Patel]

Hello there,

Please try this solution. This works for me.

As For Ubuntu 18.04, python-pygoocanvas is no longer provided. The ns-3.29 release and later upgrades the support to GTK+ version 3, and requires these packages: sudo apt-get install gir1.2-goocanvas-2.0 python-gi python-gi-cairo python-pygraphviz python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython

I hope this helps.

Regards,

Jay Patel

It is not working for you because you are trying to install packages
from an unprivileged user account; you must either use sudo or change to
a root shell.

Hi,

Please use sudo or change to a root shell and it should work.

Hi Fatima,

 I got the same problem but I solved it by  installing python2 instead of python 3

install these first:

sudo apt-get install gir1.2-goocanvas-2.0 python-gi python-gi-cairo python-pygraphviz python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython ipython3

pip install PyBindGen

navigate to where waf is located.

then, specify which python interpreter to use for ns3 python binding

use latest version of python2:

/usr/bin/python2.7 ./waf configure

then, build:

./waf build --enable-examples --enable-test

once built, running any ns3 simulation in scratch folder should be able to be visualized.

when running the simulation, place --vis flag to ensure visualization.

for example:

./waf --run your_simulation_name --vis

Dear Lin,

Many thanks for your kind response and help.

The python visualizer is enabled, but got a new problem

Good morning all

I thank you very much for your answers

I followed what you told me and I had this problem despite visualizer  is built

I made an example with the third --vis and here are the results

can you tell me please what is the problem?

[Radha Reddy]

Dear Fatima,

Many thanks for your kind response and concern.

The problem has been solved by updating the python version.

Regards

Radha

Dear all,

I also have a same problem. I followed all of your instructions, but still when I run an example, this error appears:

Could not load icon applets-screenshooter due to missing gnomedesktop Python module

And whenever I try to install python-gnome2-desktop, this error appears:

E: Unable to locate package python-gnome2-desktop

Does anyone know how I can install it?

Thanks,

Narges
