Bug on pyreverse

[fcabaud]

I got this bug in pyreverse

pyreverse -c PyreverseCommand -a1 -s1 -f ALL -o png ../mypath/myfile.py

parsing ../src/py/deminer/deminer_orchestrator.py...

Traceback (most recent call last):

Did you solve it? I also encountered the same one.

[DudeNr33]

Can you provide a minimal example how to reproduce the crash, together with information which pylint version and OS you are using?

[ly3106]

The source file I parsed is train.py on here.

Versions are as follows: ubuntu 18.04 pylint 2.13.5 astroid 2.11.2 Python 3.6.9 (default, Mar 15 2022, 13:55:28) [GCC 8.4.0]

And following is my command (but if I use pyreverse -f ALL -ASmy ./train.py, it works well)

.../Point-GNN$ pyreverse --module-names=y --class=module.entry.SumoRunner ./train.py
parsing ./train.py...

Thank you for the example. Where is module.entry.SumoRunner coming from? Is this an external dependency?

[ly3106]

Thank you for your help. I think I make some mistakes as I am not so familiar with pyreverse. According to your hint, I changed the command to pyreverse --module-names=y -ASmy ./train.py, and it works very well. Thank you very much again.

I'm going to close as answered / hard to reproduce without precision.
