ICEModel KeyError: 'com' #237
Description
Describe the bug
I run the tutorial code of ICEmodel. And it produces the error code:
0%| | 1/200 [00:00<00:00, 853.37it/s]
---------------------------------------------------------------------------
KeyError Traceback (most recent call last)

KeyError: 'com'
To Reproduce
The tutorial code I run:
import networkx as nx
import ndlib.models.ModelConfig as mc
import ndlib.models.epidemics as ep
g = nx.erdos_renyi_graph(1000, 0.1)
# Model selection
model = ep.ICPModel(g)
# Model Configuration
config = mc.Configuration()
config.add_model_parameter('fraction_infected', 0.1)
config.add_model_parameter('permeability', 0.3)
# Setting the edge parameters
threshold = 0.1
for e in g.edges():
config.add_edge_configuration("threshold", e, threshold)
model.set_initial_status(config)
# Simulation execution
iterations = model.iteration_bunch(200)
- NDlib version
- Operating System
- Python version
- Version(s) of NDlib required libraries
Expected behavior
I guess this issue is probably the community information is not inputted into the model.params['node']
The tutorial code does not run any community detection analysis. And the model.params['node'] gives an empty dict.
