Pytorch Geometric: 'from_networkx' doesn't work with my 'group_node_attrs' Question: I’ trying to convert a NetwrokX graph into the pyg format to feed it to a GCN. from_networkx(G) works without problems from_networkx(G, group_node_attrs=x) # doesn’t work, and I get the following error: Here the documentation about how the function ‘from_networkx’: https://pytorch-geometric.readthedocs.io/en/latest/_modules/torch_geometric/utils/convert.html Traceback (most recent call last): …

Set z-order of Edges in Pandas Dataframe Question: I’m using OSMnx to create some plots of road networks with data shown by colour, below is an example which produces an image with colour showing betweenness centrality. The problem I’m having is that, due to the zordering, some of the lighter regions are covered by other …

How to get an isomorphic graph from another in networkx? Question: Good morning, everyone. I am currently doing a unit test of a function that processes graphs and it should give similar results in front of isomorphic graphs. So, I would like to output only an isomorphic graph from a networkx graph, but I can’t …

Ignore non-connected nodes in NetworkX Graph Question: I have a network diagram where a node is connected to another node which in-turn is connected to another node, worked through a logic to ignore when there is only one neighbour but that is still leaving few bits back. The attached diagram does a better job explaining …

Unable to embed networkx graph using matplotlib in customtk Question: I’m trying to embed a networkx graph in CustomTk, but the graph doesn’t appear. When I use plt.show() I can see the graph in matplotlib pop-up menu, but not in GUI. import tkinter import customtkinter import networkx as nx from matplotlib.backends.backend_tkagg import ( FigureCanvasTkAgg, NavigationToolbar2Tk) …

Get weight combining edges in Networkx Question: Hello I am using Networkx with Python to make some graphs. After extracting the edges from a .CSV structured as "source" and "target" I got a list of edges like this: edges = [(a,b), (a,c), (b,c), (a,b), (a,b), (a,c)] Is there any way to build ( after creating …

Networkx: select nodes only if they have a given attribute Question: Here is a sample graph based on the code of a previous question ("How can I select nodes with a given attribute value"): import networkx as nx P = nx.Graph() P.add_node("node1", at=5) P.add_node("node2", at=5) P.add_node("node3", at=6) # You can select like this selected_data = …

networkx: Assigning node colors based on weight when using bbox Question: I want to draw a graph with networx and render the nodes as boxes wide enough to contain each node’s name, colored according to its weight. If I use the default shape, they are colored correctly, but when I use the bbox parameter facecolor, …
