I am using PubNub python Tornado SDK 4.2.1 with python 3.6
https://www.pubnub.com/docs/python-tornado/api-reference-configuration
And I am trying to initialize PubNubTornado with following code,

pnconfig = PNConfiguration()
pnconfig.subscribe_key = os.environ['SUB_KEY']
pnconfig.publish_key = os.environ['PUB_KEY']
pnconfig.ssl = True
pubnub = PubNubTornado(pnconfig)
but it gives the following error

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
I'm trying to create a HttpSensor in Airflow using the following code:
wait_to_launch = HttpSensor(
task_id="wait-to-launch",
endpoint='http://' + socket.gethostname() + ":8500/v1/kv/launch-cluster?raw",
response_check=lambda response: True if 'oui'==response.content else False,

But I keep getting this error:

What am I missing?
You are running into a known issue, see AIRFLOW-1030. A fix has been merged (#2180), but unfortunately is not yet on a released version of airflow. The fix is marked for the next release (1.9.0), but it could be weeks/months until that is out. You can run a fork of airflow with this change or add the updated version of the HttpSensor as a custom operator (plugin).
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.
