[gdal-dev] Python error in me or in gisinternals.com packages?

[Even Rouault]

Hi Jukka,

I just checked and indeed gisinternals uses SWIG 2 to generate python 
bindings, which is not Python 3 compatible. I've added a comment in 
https://github.com/gisinternals/buildsystem/issues/180#issuecomment-952121822 
about that
