How to avoid the GeocoderTimedOut('Service timed out') error in GeoPy using the OSM Nominatim geocoder? I am not interested in using an exception and skip some entries. I already use a time delay of 1.1 seconds in my script using time.sleep(1.1). Total database is 10,000 entries.

You could make a recursive function. Just typing Python-esque pseudo-code:

from geopy.exc import GeocoderTimedOut

def do_geocode(address, attempt=1, max_attempts=5):
    try:
        return geopy.geocode(address)
    except GeocoderTimedOut:
        if attempt <= max_attempts:
            return do_geocode(address, attempt=attempt+1)
        raise

Documentation for geopy.exc.GeocoderTimedOut.

This will keep retrying the do_geocode function until it manages to return without a Timeout exception being raised. You might want to limit the number of attempts, or also set a waiting period after a failed attempt. You might also want to think about why a timeout is occurring. Geopy allows you to set the length of time to wait before raising a timeout error, for any of the geocoding methods, with the timeout keyword argument. The documentation says that "some services are consistently slow", and recommends that this be increased.

  • thanks. this was indeed part of the solution. Make sure to import: from geopy.exc import GeocoderTimedOut – RutgerH Mar 11 '16 at 15:19
  • Hi, this did not work for me, I'm getting: HTTPSConnectionPool(host='nominatim.openstreetmap.org', port=443): Max retries exceeded with url: /reverse?lat=32.782023&lon=35.478867&format=json&accept-language=en&addressdetails=1 (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x000001F7AA876240>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it',)) – user88484 Sep 1 '20 at 6:50
  • @user88484 You may have exceeded their rate limits. operations.osmfoundation.org/policies/nominatim Maximum of one request per second. – alphabetasoup Sep 1 '20 at 22:49

Pass None to disable timeout.

location = geolocator.geocode(county, timeout=None)
