** If you are getting GEOSException, this is a known bug in this python package, and there is a quick fix. You need to edit function geos_version_info inside site-packages/django/contrib/gis/geos/libgeos.py, where you will replace the line ver = geos_version().decode() with ver = geos_version().decode().split(' ')[0].
