Question

我将csv解析为pandas，然后解析为geopandas from here 我创建了stations DataFrame，其中包含以下内容：

stations_pd['pos'] = [Point(loc[0], loc[1]) for loc in locs]

然后我从中创建了地址：

stations_gpd = gpd.GeoDataFrame(stations_pd)

并希望将其转储到HDFStore：

store = pd.HDFStore("test.h5")
store['pd'] = stations_pd

这很好，但与geopnadas相同会引发错误：

store['gpd'] = stations_gpd

错误是：

File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pandas/io/pytables.py", line 486, in __setitem__
    self.put(key, value)
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pandas/io/pytables.py", line 866, in put
    self._write_to_group(key, value, append=append, **kwargs)
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pandas/io/pytables.py", line 1323, in _write_to_group

  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pandas/io/pytables.py", line 1237, in _create_storer

  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pandas/io/pytables.py", line 1213, in error

TypeError: cannot properly create the storer for: [_TYPE_MAP] [group->/stations (Group) '',value-><class 'geopandas.geodataframe.GeoDataFrame'>,format->fixed,append->False,kwargs->{'encoding': None}]

将geopandas倾倒到HDFStore
