Contracted nodes automatically in Networkx

I have problem, I wish could automatically merge the nodes by inserting an if condition. I have this dataframe: Individuals Weight Source Destination 0 (10.0.12.100, 10.0.1.1) …

Networkx: Update single attribute of all nodes within a graph without for loop

I have some code that can update a graph’s attribute: import networkx as nx def update_nodes(graph): values = dict.fromkeys(graph.nodes, True) nx.set_node_attributes(graph, name=’…

Plot cumulative distribution with networkx and numpy

I want to implement the cumulative distribution for a graph. Here is my code: g = nx.read_edgelist(‘graph’, create_using= nx.Graph(), nodetype=int) degree_sequence = sorted([d for n, d in g.degree()], …

Creating multiple graphs using gnp_random_graph

While using the NetworkX package I was tasked with creating multiple random graphs with a given n number of nodes and p probability, this is my code: def random_networks_generator(n,p,num_networks=1, …

How to import csv format Adjacency Matrix hashtag network in CSV file?

Error for max(nx.connected_component_subgraphs(),) no attribute ‘connected_component_subgraphs’

I am trying to run this code: graph = nx.Graph() largest_subgraph = max(nx.connected_component_subgraphs(graph), key=len) But I am getting this error message: AttributeError: module ‘networkx’ has …

How to connect two nodes if they are disconnected

I use a python NetworkX graph. How to check if 2 nodes are disconnected and then get a new version of the graph where these 2 nodes are connected. The difference between 2 graphs should have min edit distance (Levenshtein distance) Before and after for nodes=[1,2]: | Answer you can also have a condition to check for an edge of either direction with:

How to update a NetworkX plot in real-time?

I’m trying to update a networkx plot using matplotlib in a canvas, but it adds a new plot to the graph each time instead of updating the graph below, I had to add the call to nx.draw_networkx() function to get it to update and I’m not sure if this is part of the issue. Example Code: Answer I have found a similar question and answer after a lengthy search on this question here however for clarity and because i also used code from elsewhere you must use the G.clear() to clear the current nodes and edges from the graph. plt.clf()

Combine (join) networkx Graphs

Say I have two networkx graphs, G and H: What is the best way to join the two networkx graphs? I’d like to preserve the node names (note the common nodes, 2 to 7). When I used nx.disjoint_union(G,H), this did not happen: The H node labels were changed (not what I want). I want to join the graphs at the nodes with the same number. Note. This is not a duplicate of Combine two weighted graphs in NetworkX. Answer The function you’re looking for is compose, which produces a graph with all the edges and all the nodes that are

I’m trying to perform the transitive reduction of directed graph in Python

As a warning, I’m still a bit inexperienced in python I’m trying to perform the transitive reduction of directed graph using the networkx library. I’ve figured out an algorithm but I’m having trouble implementing it. After a quick search, I found algorithms similar to mine in other stack exchange questions but no demonstrations of how to actually code the algorithm. Here’s my algorthm: Here’s my attempt at expressing this in python : I don’t think I’m properly calling every permutation of edges in the network and was thinking of trying to use itertools. Even if I had every possible permutation,
