How to update graph in networkx after removing nodes?










2















I want to update the definition for my graph after removing nodes and edges however when I try to draw it again I get the error that it is missing a node, i.e. the one I removed.
Here is my example code:



a = k(n) #This is a graph function which works fine returning a graph
remove_node = 54
a.remove_node(54)
nx.draw(a)





NetworkXError: The node 54 is not in the graph.

    This code does not produce an error for me. It will help if you give the complete error message. But I think the problem is that a doesn't have node 54 to begin with, and the error is coming when you try to remove it. The full error message would make that clearer.
