2 years ago As first step make sure that you are using the most recent version of pynauty, that is 1.1.1
If you still get the error, provide the complete error message, the version of python, and the platform, operating system with versions you are using. Also whether you built pynauty from source or used a binary wheel from pypi.
The program you linked too complicated and has many dependencies. Try to provide as simple an example as you can (preferably just a few lines of code, and a small graph/data).
The isomorphism tests call canon_label but as far as I know all passes, none of the call crashes.
Over-TheRainbow
I didn't know where else to ask this, so I'll ask it here. I was trying to get a code demo I found online to work, that uses pynauty's canonical_labelling. I noticed that when I installed pynauty, there is no such function but there is canon_label, but when I replaced the function call, it came up with the error Illegal instruction (when inputting a pynauty Graph into canon_label). After looking around, I saw a test folder, which had a test with canon_label, so I went to the pynauty directory and ran the command pytest, but I also got the error Illegal instruction. I'm not sure if this is an error caused by my misunderstanding of the usage of the function, or some sort of bug, so I am posting this question here. (https://github.com/tvayer/PSCN/blob/master/pscn.py is the file that uses the canonical_labelling)
