Visualization¶
PyNTM has a visualization feature that produces an interactive visualization of the network.
More info on the visualization and how to use it can be found in the pyNTM training repository visualization training module.
Visualization Demo Script¶
The examples/vis_training.py example script showcases the visualization module, which is current beta feature.
To run this script, install the packages in requirements_visualization.txt file:
(venv) % pip3 install -r requirements_visualization.txt
Once you’ve installed the requirements, run the script.
You will see some simulation activities and info and then a visualization:
(venv) % python3 -i vis_training.py
Routing the LSPs . . .
Routing 1 LSPs in parallel LSP group C-E; 1/3
Routing 1 LSPs in parallel LSP group D-F; 2/3
Routing 2 LSPs in parallel LSP group B-D; 3/3
LSPs routed (if present) in 0:00:00.001134; routing demands now . . .
Demands routed in 0:00:00.003497; validating model . . .
shortest path from A to F is:

*** NOTE: The make_visualization_beta function is a beta feature. It may not have been as
extensively tested as the pyNTM code in general. The API calls for this may also
change more rapidly than the general pyNTM code base.
