I have a python3 script using the networkx and matplotlib libraries. An example sample is as follows:
Code:
#! /usr/bin/env python3

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
import networkx as nx

if __name__ == '__main__':

    vertices = range(1, 10)
    edges = [(7,2), (2,3), (7,4), (4,5), (7,3), (1,6), (1,7), (2,8), (2,9)]

    G = nx.Graph()
    G.add_nodes_from(vertices)
    G.add_edges_from(edges)

    nx.draw(G)
    plt.savefig("node.png")

When the script get's to: nx.draw(G), the following error message is displayed:
Code:
Traceback (most recent call last):
  File "./05_imaging.py", line 17, in <module>
    nx.draw(G)
  File "/usr/local/lib/python3.7/site-packages/networkx/drawing/nx_pylab.py", line 126, in draw
    draw_networkx(G, pos=pos, ax=ax, **kwds)
  File "/usr/local/lib/python3.7/site-packages/networkx/drawing/nx_pylab.py", line 278, in draw_networkx
    edge_collection = draw_networkx_edges(G, pos, arrows=arrows, **kwds)
  File "/usr/local/lib/python3.7/site-packages/networkx/drawing/nx_pylab.py", line 563, in draw_networkx_edges
    if not cb.iterable(width):
AttributeError: module 'matplotlib.cbook' has no attribute 'iterable'

It seems that this is an issue of 'matplotli.cbook' being deprecated since version 3.0 of matplotlib. Is there any way to get around this issue since the py37-networkx package requires py37-matplotlib and the py37-matplotlib package is currently at the 3.3.1 version of matplotlib?

Just for information, I have no issues with matplotlib alone. About
matplotlib.use('Agg')
I have used matplotlib.use('TkAgg') in some other tools I have not checked right now. I do not know if there is a difference between Agg and TkAgg.
