Hi, I can't believe I have to explain this, but this is the mailing list for graph-tool, not for igraph. Please refer to the igraph mailing list for help. Best, Tiago Am 21.09.22 um 12:21 schrieb Jos J:
I have python 3.8.13, igraph 0.10.1, with matplotlib 3.6.0, and when running the sample scripts from the install page on the website, I am receiving an error. The scripts can be found here: https://igraph.org/python/tutorial/latest/install.html <https://igraph.org/python/tutorial/latest/install.html>
I am referring to the following
import matplotlib.pyplot as plt import igraph as ig fig, ax = plt.subplots() g = ig.Graph.Famous("petersen") ig.plot(g, target=ax) plt.show()
I receive the following errors at the ig.plot(g, target=ax) line:

Not sure if its my python or package versions, or if its a configuration issue, or possibly an issue with igraph or matplotlib. Any advice would be most welcome
