download streets from different address in OSMNX-CodePudding

i would like to download different streets in osmnx, using a list but i can't find the error in my code.

i tried this way

name_list = ['Kuwait, United Arab Emirates','Guangzhou, China']

i=0
for file_path in name_list:
    print(i)
    CD = file_path
    filtro_vialidades = '["highway"~"trunk|motorwat|primary|secondary|tertiary|residential"]'
    GCD=ox.graph_from_address(CD, network_type= "drive",
                              custom_filter= filtro_vialidades)
    ox.save_graphml(GCD, f"{name_list[i]}.graphml", gephi= False)
    i =1  

#I had this error

EmptyOverpassResponse: There are no data elements in the response JSON

CodePudding user response：

It looks like it cannot find anything for one of your queries, probably because "Kuwait, United Arab Emirates" does not exist. These are two separate countries.

CodePudding user response：

Kuwait is a country not a city. You can add appropriate error handling code:

import osmnx as ox
from osmnx._errors import EmptyOverpassResponse

name_list = ['Kuwait, United Arab Emirates','Guangzhou, China']

for i, file_path in enumerate(name_list):
    print(i)
    CD = file_path
    filtro_vialidades = '["highway"~"trunk|motorwat|primary|secondary|tertiary|residential"]'
    try:
        GCD=ox.graph_from_address(CD, network_type= "drive",
                                  custom_filter= filtro_vialidades)
        ox.save_graphml(GCD, f"{name_list[i]}.graphml", gephi= False)
    except EmptyOverpassResponse:
        print(f"no results: {file_path}")
