networkx

问题 I have created a graph using networkx in Python . import networkx as nx G = createGraph ('abc.csv') #My function that returns graph from file. connected_components = nx.connected_components(G) print (connected_components) <generator object connected_components at 0x00000000221EF1A8> nbr_cc = nx.number_connected_components(G) print (nbr_cc) 57215 I want to convert every connected component into a clique and then write a csv file in following manner: node1_id node2_id connected_component_id 1 2

问题 I'm using the wonderful OSMnx library created by Geoff Boeing. I am plotting a street network based on one of his tutorials. Everything works perfectly. However, I would like to plot more than 40 graphs, using different centralities. Therefore, I would like to add a title with each district and centrality name to each plot. Currently, it looks like this. Plotted OSMnx Street Network This is what my code looks like. def display_most_important_node(G_centralities_sorted_dict, G_dictionary,

问题 I am trying to find all 3-cliques using networkx's find_cliques method. However, there should be far more than 2 as the result shows. Please help me to figure out why. import networkx as nx G = nx.Graph() edges_fig_4 = [('a','b'),('a','c'),('a','d'),('a','e'), ('b','c'),('b','d'),('b','e'), ('c','d'),('c','e'), ('d','e'),('e','d'), ('f','b'),('f','c'),('f','g'), ('g','f'),('g','c'),('g','d'),('g','e')] G.add_edges_from(edges_fig_4) cliques = nx.find_cliques(G) cliques3 = [clq for clq in

问题 I am implementing a graph manipulation script and I was puzzled with the following error: Traceback (most recent call last): File ".....py", line 12, in <module> print(len(graph.predecessors(i)), len(graph.successors(i))) >>TypeError: object of type 'dict_keyiterator' has no len()<< This is the code: import networkx as nx graph = nx.DiGraph() for i in range(10): graph.add_node(i) for i in range(9): graph.add_edge(i, i+1) for i in range(10): print(len(graph.predecessors(i)), len(graph

问题 I've been trying to parse in some additional attributes to a networkx gml for use later on, and I've run into an issue. When given a gml file from Cytoscape, networkx outputs a gml file that it itself can't read. I.e. Cytoscape -> Into networkx -> Output -> Into networkx -> Error: pyparsing.ParseException: Expected "]" (at char 1116756), (line:71732, col:3) Now that error requests an additional ] after the nodes (AKA making the graph ignore the edges), if you do this, the graph works. However

问题 I am fairly proficient in C++, but I am learning python, NetworkX, and about pythonic code all at the same time. After reading various websites and the reference my question is the same as this question. The difference is the approach I am taking to implement my task. Please note this question is about adding an edge, not drawing. I have a graph (SAR), whose nodes are also graphs (Boat, and Adrift), import networkx as nx import math # User Inputs Num_Adrift = 4 # Cluster Definition Boat = nx

问题 I'm using NetworkX 1.9.1. I have a graph that I need to organize with positions and I then export to graphml format. I've tried code in this question. It does not work, here is my example import networkx as nx import matplotlib.pyplot as plt G = nx.read_graphml("colored.graphml") pos=nx.spring_layout(G) # an example of quick positioning nx.set_node_attributes(G, 'pos', pos) nx.write_graphml(G, "g.graphml") nx.draw_networkx(G, pos) plt.savefig("g.pdf") Here are the errors I get, the problem is

问题 I'm trying to plot the graph of edge centrality on the folium using the following code graph_map = ox.plot_graph_folium(G, popup_attribute='name', tiles='stamenterrain', edge_color=ec, edge_width=2) where ec is list of edge colors but it is not showing up. Does edge_color accept a list of colors ? Any ideas? I really appreciate if you can help me. https://github.com/gboeing/osmnx-examples/blob/master/notebooks/08-example-line-graph.ipynb 回答1: I tried adding a new column of edge color to gdf
