TypeError: draw_networkx_edges() got an unexpected keyword argument 'with_labels'

[Ru-Zheng]

my codes:
import networkx as nx
import EoN
import matplotlib.pyplot as plt

G = nx.watts_strogatz_graph(100, 5, 0.9)
nx_kwargs = {"with_labels": True}

sim = EoN.Gillespie_SIR(G, 1, 0.1, return_full_data=True)

t = 0.0
while t < 40:
sim.display(time=t, **nx_kwargs)
plt.show()
t += 0.5

tree = sim.transmission_tree()
hierarchy_tree = EoN.hierarchy_pos(tree)
nx.draw(tree, hierarchy_tree, with_labels=True)
plt.show()

---

However,I meet some problem:

Traceback (most recent call last):
File "D:\python_project\sir.py", line 15, in
sim.display(time=t, **nx_kwargs)
File "D:\python3.9.10\lib\site-packages\EoN\simulation_investigation.py", line 875, in display

nx.draw_networkx_edges(self.G, pos, edgelist=edgelist, ax=ax, **nx_kwargs)
TypeError: draw_networkx_edges() got an unexpected keyword argument 'with_labels'

Can you help me to solve this problem,thank you.

Hi,

Can you give me information about what version of networkx you're running?

This is odd because that code runs okay for me. The error is suggesting that when EoN calls draw_networkx_edges, it is sending an argument that the networkx method isn't expecting.

Hi,
My networkx version is 2.8.2,when I rewrite simulation_investigation.py line 639:nx.draw_networkx_edges(self.G, pos, edgelist=edgelist, ax=ax, **nx_kwargs) to nx.draw_networkx(self.G, pos, edgelist=edgelist, ax=ax, **nx_kwargs), it is worked.

You may want to add nodelist = [] to the edited function call. This was obviously supposed to only draw the edges (with the nodes handled separately), but the version you're calling will also draw all the nodes in this call. I think adding nodelist=[] will prevent that.
