我正在使用Python，我正在尝试使用osmnx来查询OpenStreetMap并获取有关意大利城市布雷西亚的数据。
这是我从文档复制的代码。
import osmnx as ox
place = "Brescia, Italy"
osmnx_buffer = 10000 # in metres
g = ox.graph.graph_from_place(place, buffer_dist=osmnx_buffer)
g = ox.projection.project_graph(g)
ox.plot_graph(g)
我唯一改变的是字符串的内容
place问题是，当我运行脚本时，它永远不会回复（因此，永远不会绘制任何内容）。我尝试阅读文档并更改我的查询，但我不知道它出了什么问题。你能建议我如何让这个脚本工作吗？
我的目标是与
networkx提前谢谢您。
您的代码似乎一切正常（我刚刚成功运行了它）。但请注意，您传递的
buffer_dist这是示例代码以及日志输出：
import osmnx as ox
ox.settings.log_console = True # turn on logging
place = "Brescia, Italy"
# buffer the study area by 10 km
geom = ox.geocode_to_gdf(place).iloc[0]["geometry"]
geom_proj, crs = ox.projection.project_geometry(geom)
geom_buff, _ = ox.projection.project_geometry(geom_proj.buffer(10000), crs=crs, to_latlong=True)
# get the graph and plot it
G = ox.graph_from_polygon(geom_buff)
Gp = ox.project_graph(G)
fig, ax = ox.plot_graph(Gp)
和日志输出：
