Segmentation Fault

[Nadianw36]

Segmentation Fault Error I'm running into a Segmentation Fault even when I run it on a very small network -- I actually run it on the example code given on the documentation page. Error/Output:

Infomap v2.5.0 starts at 2022-07-11 13:16:10 -> Input network: -> No file output! -> Configuration: two-level directed zsh: segmentation fault python3 -m pdb test_clustering.py

Code:

im.add_link(0, 1)
im.add_link(0, 2)
im.add_link(0, 3)
im.add_link(1, 0)
im.add_link(1, 2)
im.add_link(2, 1)
im.add_link(2, 0)
im.add_link(3, 0)
im.add_link(3, 4)
im.add_link(3, 5)
im.add_link(4, 3)
im.add_link(4, 5)
im.add_link(5, 4)
im.add_link(5, 3)
print("graph created")
im.run()

I stepped through the code using pdb and saw that it occurs after this line return _infomap.InfomapWrapper_run(self, *args) so I think it's something about the way the args are being converted between python to C++.

Is there something wrong with the way I downloaded infomap, or does anyone have insight on what is going wrong?

Hi, thanks for reaching out. Can you show your code from the beginning where you import infomap and creating im?

You should have something like:

from infomap import Infomap

im =  Infomap(two_level=True, directed=True)
