networkx

问题 I would like to obtain something similar to this: using the python library networkx. I can generate a similar directed graph using the following code: import matplotlib.pyplot as plt import networkx as nx G = nx.DiGraph() G.add_edge('1','2') G.add_edge('1','3') G.add_edge('3','2') G.add_edge('3','4') G.add_edge('4','3') nx.draw(G, node_color='w', edgecolors='k', width=2.0, with_labels=True) plt.show() which produces: However, the arrows between the nodes 3 and 4 are superimposed, and it just

问题 My dataframe has 3 columns, source , target and value. it looks like this source target value BOBA FETT C-3PO 4 BOBA FETT CHEWBACCA 3 BOBA FETT DARTH VADER 8 BOBA FETT HAN 7 G = nx.from_pandas_edgelist(links,source='source',target='target', edge_attr='value') I use this to add my edgelist nx.draw_networkx_edge_labels(G,pos=nx.Graph(G),edge_labels={(u,v):w for u,v,w in G.edges(data='value')}) I tried this to show edge labels. I want the 'value' to be dispplayed as my edge label it gives this

问题 I have a network formed with two Polygons and I want to now which nodes are only in the bigger Polygon. How can I do this? Here is the code: import osmnx as ox import igraph as ig import matplotlib.pyplot as plt import pandas as pd import networkx as nx city = ['Portugal, Lisbon', 'Portugal, Amadora'] G = ox.graph_from_place(city, network_type='drive', simplify=True) G_nx = nx.relabel.convert_node_labels_to_integers(G) nodes, edges = ox.graph_to_gdfs(G_nx, nodes=True, edges=True) Here are the

问题 I am getting a KeyError when I try to create a network. My dataset is Node Neighbors Colour Weight Luke Alte orange 3 Luke John orange 3 Michael Laura red 43 Ludo Stella orange 21 Alte Ludo blue 24 Alte Luke blue 24 The table above shows the links by nodes: node Luke is linked with Alte and John. It has edge weight 3 and colour orange node Michael is linked with Laura. It has weight 43 and colour red node Ludo is linked with Stella. It has weight 21 and colour orange node Alte is linked with

问题 I have points as x,y and I want to plot my graph using the (x,y) coordinates of my points list so that I can see the axis. here are my code and photo of the graph import networkx as nx import matplotlib.pyplot as plt def add_edge_to_graph(G,e1,e2,w): G.add_edge(e1,e2,weight=w) G=nx.Graph() points=[(1, 10), (8, 10), (10, 8), (7, 4), (3, 1)] #(x,y) points edges=[(0, 1, 10), (1, 2, 5), (2, 3, 25), (0, 3, 3), (3, 4, 8)]#(v1,v2, weight) for i in range(len(edges)): add_edge_to_graph(G,points[edges

问题 I have a dataset(pickle format) containing float('nan') , and I need to remove it. It is possible to add float('nan') to a graph as a node in networkx. However, I don't know how to remove it. import networkx as nx G = nx.Graph() G.add_node(float('nan')) print(G.nodes) # [nan], so there is float('nan') in the graph G.remove_node(float('nan')) # this statement raise a NetworkxError showing nan not in the graph Code and data in CoReRank-WSDM-2019 and BirdNest. Could anyone help me with this
