[GRASS-user] v.centerline addon

[cesar at fototerra.com.br]

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

/v.centerline.py", line 319, in <module>

    main()

  File "C:\Users\cesar\AppData\Roaming\GRASS7\addons/scripts

/v.centerline.py", line 111, in main

    segment_input += 'P ' + category.strip()

TypeError: can only concatenate str (not "bytes") to str

v.centerline input=Linha_rio_teste_Centerline at PERMANENT output=teste range=2
refline=2

Traceback (most recent call last):

    segment_input += 'P ' + category.strip()

I would like help to try understand what’s happening.

 

Regards.
