I am using a corporate laptop to extract latitudes/longitudes for a set of locations in Jupyter Notebook (system config: Windows 10-64bit , Python 3.8.5, pip version: 20.3.3 )- Below is the code snippet that I am using:
from googlemaps import Client as GoogleMaps
import pandas as pd
gmaps = GoogleMaps(key=xxxxx)
result = gmaps.geocode(address)
First, I run the following to disable SSL verification (which was suggested in a previous discussion):
import ssl
try:
_create_unverified_https_context =
ssl._create_unverified_context
except AttributeError:
pass
else:
ssl._create_default_https_context =
_create_unverified_https_context
Also, I downgraded certifi module to 2015.04.28 version following the discussion here: https://github.com/googlemaps/google-maps-services-python/issues/191. None of these worked and I keep getting the following SSL verification error even for a single location (same code works fine on my personal system)- I'd appreciate any feedback.
