error using geoGen package from GITHUB

[hknarahari]

Thank you Buran. As you predicted I have found a new error :
_file = open(fname)
label = _file.next().split(',')
AttributeError : '_io.TextIOWrapper object has no attribute 'next'
Can I use 'Futerize' command to fix similar errors ? I really dont want to go back to Python 2.7 version..
Regards
