合并边界报错

[hejiagail]

尝试合并边界：
beijing = get_adm_maps(province='北京市', only_polygon=True, record='first')
tianjin = get_adm_maps(province='天津市', only_polygon=True, record='first')
hebei = get_adm_maps(province='河北省', only_polygon=True, record='first')

jingjinji = beijing + tianjin + hebei
报错：
TypeError Traceback (most recent call last)
Cell In[33], line 9
6 tianjin = get_adm_maps(province='天津市', only_polygon=True, record='first')
7 hebei = get_adm_maps(province='河北省', only_polygon=True, record='first')
----> 9 jingjinji = beijing + tianjin + hebei
11 fig = plt.figure(figsize=(5,5))
12 ax = fig.add_subplot(111, projection=ccrs.PlateCarree())

TypeError: unsupported operand type(s) for +: 'MultiPolygon' and 'MultiPolygon'

@hejiagail 升级到最新版本，用pip 安装： pip install -U cnmaps
