Vehicle Routing Problem Solver takes too long and gives Time Out error

SeymaGunes — Sun, 12 Dec 2021 09:32:15 GMT

I have been working on coding a Vehicle Routing Problem Solver, mostly by following ArcGIS Guide online (Guide to Network Analysis (Part 7 - Vehicle Routing Problem) | ArcGIS for Developers ). My code is as follows:

from arcgis.gis import GIS
import pandas as pd
import getpass
from IPython.display import HTML
import arcgis
from arcgis.features import Feature, FeatureSet, GeoAccessor, GeoSeriesAccessor
import networkx as nx
import osmnx as ox
import requests
import matplotlib.cm as cm
import matplotlib.colors as colors
from pathlib import Path
import geopandas as gpd # combines the capabilities of pandas and shapely for geospatial operations
#connect to your GIS
gis = GIS( client_id='Db8G5Jo6FCgLqTLk')
print("Successfully logged in as: " + gis.properties.user.username)
data_path = Path('./data')
if not data_path.exists():
   data_path.mkdir()
#read shape file
addresses = gpd.read_file('data/Addresses_in_King_County___address_point-shp/Addresses_in_King_County___address_point.shp')

Can you put print(xxx) statement after each step so that you single out

what block has an issue?
