How can I load a map using pyrosm?

Well, what I'm trying to do is open a map and, with two georeferenced points, try to calculate the distance between them via a highway.

Using the ([https://pyrosm.readthedocs.io/en/latest/basics.html](pyrosm example)) I created the following code:

from pyrosm import OSM, get_data
import osmnx as ox
import time

osm = OSM(get_data("sudeste", directory="/home/brunob/mapas"))

buildings = osm.get_buildings()
buildings.plot()

drive_net = osm.get_network(network_type="driving")
drive_net.plot()

And I recieved this error:

 Traceback (most recent call last):
 File "/home/brunob/códigos/plotando_mapa.py", line 18, in <module>
 drive_net = osm.get_network(network_type="driving")
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

File "pyrosm/_arrays.pyx", line 79, in pyrosm._arrays.convert_to_arrays_and_drop_empty
TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType'

What is my error?

Thanks for any help

I solve the problem using osmnx only

import osmnx as ox
import networkx as nx
import os
import time

def carregar_grafo(lugar, caminho_arquivo):
    if os.path.isfile(caminho_arquivo):
        return ox.load_graphml(caminho_arquivo)
    else:
        G = ox.graph_from_place(lugar, network_type="drive_service")
        ox.save_graphml(G, caminho_arquivo)
        return G

tempo_inicial = time.time()

localizacao = 'estado de São Paulo, Região Sudeste, Brasil'

arquivo = !pwd
arquivo = str(arquivo[0]) + '/mapas/estado_sp.graphml'
G = carregar_grafo(localizacao, arquivo)

tempo_final = time.time()

print("--- %s segundos ---" % (tempo_final - tempo_inicial))


# impute missing edge speeds and add travel times
G = ox.add_edge_speeds(G)
G = ox.add_edge_travel_times(G)

for adresses I use the open street map site, look for right words to ox.graph_from_place function.

That's it, the pyrosm bib is not updated (until now).
