Note: "scratch" programs do not need this step, they already link to the visualizer module by default.įor non-scratch programs, find the wscript that declares the program, and modify it, such as:ĭiff -r fbeb6b1cca20 src/olsr/examples/wscript In ns version 3.11 and later, you first need to add the 'visualizer' module to your program, as a dependency. You will have to select one of those branches, and merge it with your code.Įnabling the visualizer in your own simulation current ns-3 gjc/ns-3-pyviz-dev: this branch was based on the current NS-3 development version, ns-3-dev, but seems to be no longer maintained.gjc/ns-3.9-pyviz: this branch is based on NS-3.9.gjc/ns-3.8-pyviz: this branch is based on NS-3.8.gjc/ns-3.7-pyviz: this branch is based on NS-3.7.gjc/ns-3-pyviz: this branch is based on the old NS-3.2 version.There are multiple branches of PyViz, merged with different versions of NS-3: waf -pyrun src/flow-monitor/examples/wifi-olsr-flowmon.py -visĪnd the result should be something similar to the screenshot below:įor earlier ns-3 versions, PyViz is found on a separate branch. You can test the visualizer for example with the FlowMonitor sample program: Port install py27-pygtk py27-pygoocanvas py27-pygraphvizĬonfigure and build your ns-3 tree as usual, and make sure NS-3 Python bindings are enabled pyviz will not work without Python bindings!
Note that ns-3 (as of ns-3.22) is only compatible with Python 2.7 or older, not Python 3.įor example, using MacPorts and python27, the following additional package installations made PyViz available on an OS X Yosemite machine: The specific package names depend on which version of python you are using and which package manager is being used for Python packages (default MacPython, or MacPorts, or Homebrew, or pip). On OS X, you need to install the pygtk, pygoocanvas, and pygraphviz packages. Yum install python-devel gnome-python2 gnome-python2-gnomedesktop gnome-python2-rsvg graphviz-python pygoocanvas python-kiwi Optionally, you may install Interactive Python in order to have a Console button in the visualizer GUI: Python-gnome2 python-gnomedesktop python-rsvg Sudo apt-get install python-dev python-pygraphviz python-kiwi python-pygoocanvas \ Following installation instructions (for Ubuntu/Debian): You will need to have certain python modules installed. For earlier versions, see the section below. PyViz has been integrated into mainline ns-3, starting with version 3.10. Although it is mostly written in Python, it works both with Python and pure C++ simulations. There's also a builtin interactive python console that can be used to debug the state of the running objects. to figure out if mobility models are what you expect, where packets are being dropped, etc. It can be most useful for debugging purposes, i.e. NS-3 PyViz is a live simulation visualizer, meaning that it uses no trace files. 3 Enabling the visualizer in your own simulation.
