Hello!!!
I’m new user on GRASS and I’m trying to execute the addon v.centerline
on GRASS 7.9. As input I’m using a shapefile containing line
(MultiLineString) as geometry and when I have run the v.centerline an
erro is returning:
*“Traceback (most recent call last):*
* File "C:\Users\cesar\AppData\Roaming\GRASS7\addons/scripts*

I would like help to try understand what’s happening.
I would guess that this is a Python 3 vs Python 2 issue. I never updated
the addon to Python 3. If someone else can do this, it would be great,
as I'm currently on mission abroad and do not really have the necessary
access to the development tools to do this from here.
