zero-size array Erro in OrdinaryKriging about pykrige

[jsbluekitty]

And this is my new code:

Data = geopandas.read_file('./housepricepoi.shp').to_crs('EPSG:4547')
Data = Data.drop_duplicates(['geometry'])
ok3d = OrdinaryKriging(Data['geometry'].x, Data['geometry'].y, Data['price'])

k3d1, ss3d = ok3d.execute("grid", grid_lon, grid_lat)

this is the info of Data:

<class 'geopandas.geodataframe.GeoDataFrame'>
Int64Index: 1585 entries, 0 to 9877
Data columns (total 2 columns):
 #   Column    Non-Null Count  Dtype   
---  ------    --------------  -----   
 0   price     1585 non-null   int64   
 1   geometry  1585 non-null   geometry
dtypes: geometry(1), int64(1)
memory usage: 37.1 KB

it's still raise the erro:
ValueError: zero-size array to reduction operation maximum which has no identity
