NetworkX: draw_networkx not drawing labels:, draw results in'_AxesStack' object is not callable

Question

Trying to draw two nodes graph with latest version of networkx-3.0 and latest version of matplotlib-3.6.3 . Drawing does not show labels on the plot:

import networkx as nx
import matplotlib.pyplot as plt

G=nx.Graph()
G.add_node(1, text='foo')
G.add_node(2, text='bar')
G.add_edge(1,2)
print("Node labels: ", nx.get_node_attributes(G, 'text'))
nx.draw_networkx(G, with_labels=True)
>> Node labels:  {1: 'foo', 2: 'bar'}

Shows graph without labels. Why?

And this results in error:

nx.draw(G)
plt.show()

Answer 1

To answer the first question: the nx graph doesn't "know" that you want to look at its text attribute for the label, so it just goes with the initial node name.

Instead, you could pass a relabeled graph into the draw function

import networkx as nx
import matplotlib.pyplot as plt

G=nx.Graph()
G.add_node(1, text='foo')
G.add_node(2, text='bar')
G.add_edge(1,2)
print("Node labels: ", nx.get_node_attributes(G, 'text'))

nx.draw_networkx(nx.relabel_nodes(G, nx.get_node_attributes(G, 'text')), 
                 with_labels=True, node_color = 'orange')
plt.show()

The result:
