own Nominatim server not working with geopy

Question

I have a database of over 6k entries of addresses need for geocoding, thus I have installed nominatim server with docker for geocoding work. It works as it should in the web form on the 'localhost:8080'.

However, when I try to query with geopy in jupyter. It throws error all the time.

My Jupyter code:

from geopy.geocoder import Nominatim
nom=Nominatim(domain='http://localhost:8080')
nom.geocode('some address') #the address works on the public server

The error stack:

Appreciate some clues!

Answer 1

Try removing the http:// from your url and adding it as scheme parameter. In your case

nom=Nominatim(domain='localhost:8080', scheme='http')

This is due to following part in the source code

self.domain = domain.strip('/')
self.api = "%s://%s/search" % (self.scheme, self.domain)

where self.scheme is set to https by default
