I would like to use the geograpy3 package for a city & country mapping of string values, related to locations (like 'Roma, Italy' or just 'Timișoara'). It runs on my venv under OpenSuse 15.3.
Unfortunately, I can't get along with the SQLite DB. My test files always end with errors like:
sqlite3.OperationalError: no such table ...
In detail:
import geograpy
url='https://en.wikipedia.org/wiki/2012_Summer_Olympics_torch_relay'
places = geograpy.get_geoPlace_context(url = url)
print(places)
ends with:

What have I missed?
Look under your $HOME/.geograpy3/locations.db, if the file does not exist or is empty download it from here.
For more information look at this issue: https://github.com/somnathrakshit/geograpy3/issues/59

I am trying to mimic as mentioned in GIT.
I almost commented everything, and just trying to run simply
g.V().count()
my connection details are correct, and matched to documentation...
I am getting following error.

I think i got the answer.
issue was with python 3.8 & Tornado compatibility, when it comes to asyncio.
more info is at this link
fix was to add following line in tornado/platform/asyncio.py
asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy()) # python-3.8.0a4
I've already seen this answer:

JanusGraph 0.2.0 uses Apache TinkerPop 3.2.6. You should use the 3.2.6 version of the gremlinpython driver.
pip uninstall gremlinpython
pip install gremlinpython==3.2.6

In my application, an "Adapter does not support geometry" exception is being thrown when attempting to create a field of type, "geometry()". For my test application, I'm using an sqlite DB (production will use postgres):
db = DAL('sqlite://storage.sqlite', pool_size = 1, fake_migrate_all= False)
The DB table in question is declared within a class, inside of a module, and contains a several fields, some of which contain location data:
from gluon.dal import Field, geoPoint, geoLine, geoPolygon
class Info(Base_Model):
def __init__(...):
try:
db.define_table('t_info',
...
Field('f_geolocation', type='geometry()',
label = current.T('Geolocation')),
Field('f_city', type='string',
label = current.T('City')),
...
except Exception as e:
...
Edit:
As per Anthony's suggestion, I've modified the DAL constructor call to the following:
db = DAL('spatialite://storage.sqlite', pool_size = 1)
It produces the following error message:

If you want to use geometry fields with SQLite, you must use the spatialite adapter, which makes use of the SpatialLite extension for SQLite:
db = DAL('spatialite://storage.sqlite', pool_size = 1)
Note, you must have spatialite installed for this to work.
