osmnx - 我无法从地点信息中检索足迹

Question

enter code here当我尝试使用地名检索脚印时

import osmx as ox
tags = {'building': True}
gdf = ox.geometries_from_place('Piedmont, California, USA', tags)

我收到以下错误消息：

IllegalArgumentException: Argument must be Polygonal or LinearRing

PredicateError: Failed to evaluate <_FuncPtr object at 0x13a2ea120>

过去，我已经成功使用旧版本检索足迹ox.footprints_from_place()。但是，这不再起作用，新方法也不起作用。有人对 osmnx 包的新版本（1.0.1）有同样的问题吗？

由于 stackoverflow 的限制，我无法发布完整的回溯消息。似乎 osmnx 没有创建所需的多边形。第一个错误条目是：
