Python 模块numpy没有属性警告

我正试着用我自己的数据复制this个教程.我有一个简单的正方形多边形栅格:

from shapely import wkt
import pandas as pd
import geopandas as gpd

data_list = [
    [0,51, wkt.loads("POLYGON ((-74816.7238 5017078.8988, -74716.7238 5017078.8988, -74716.7238 5016978.8988, -74816.7238 5016978.8988, -74816.7238 5017078.8988))")],
    [1,91, wkt.loads("POLYGON ((-74816.7238 5016978.8988, -74716.7238 5016978.8988, -74716.7238 5016878.8988, -74816.7238 5016878.8988, -74816.7238 5016978.8988))")],
    [2,88, wkt.loads("POLYGON ((-74816.7238 5016878.8988, -74716.7238 5016878.8988, -74716.7238 5016778.8988, -74816.7238 5016778.8988, -74816.7238 5016878.8988))")],
    [3,54, wkt.loads("POLYGON ((-74816.7238 5016778.8988, -74716.7238 5016778.8988, -74716.7238 5016678.8988, -74816.7238 5016678.8988, -74816.7238 5016778.8988))")],
    [4,51, wkt.loads("POLYGON ((-74816.7238 5016678.8988, -74716.7238 5016678.8988, -74716.7238 5016578.8988, -74816.7238 5016578.8988, -74816.7238 5016678.8988))")],
]

df = pd.DataFrame(data_list, columns=["id", "data", "geometry"])
gdf = gpd.GeoDataFrame(df, geometry="geometry", crs=32633)

我已将GeoPandas GeoDataFrame转换为SpatialPandas GeodatafFrame:

from spatialpandas import GeoDataFrame

sp_gdf = GeoDataFrame(gdf)

在这一点上，我试着根据this个例子创建一个Cholopeth map :

import datashader as ds

canvas = ds.Canvas(plot_width=1000, plot_height=1000)
agg = canvas.polygons(sp_gdf, 'geometry', agg=ds.mean('data'))

但我在下面的错误中面临:

AttributeError                            Traceback (most recent call last)
Cell In[7], line 4
      1 import datashader as ds
      3 canvas = ds.Canvas(plot_width=1000, plot_height=1000)
----> 4 agg = canvas.polygons(sp_gdf, 'geometry', agg=ds.mean('data'))
      6 agg

    751     agg = any_rdn()
    752 glyph = PolygonGeom(geometry)

   1255 canvas.validate()
   1257 # All-NaN objects (e.g. chunks of arrays with no data) are valid in Datashader

   1260     return bypixel.pipeline(source, schema, canvas, glyph, agg, antialias=antialias)

    318     return Tester
--> 320 raise AttributeError("module {!r} has no attribute "
    321                      "{!r}".format(__name__, attr))

我使用的是Ubuntu 22.04和Python3.10，上面的代码在Jupyter笔记本上运行.以下是正在使用的库的版本:

• 形状:2.0.1
• Pandas :2.0.1
• 地貌:0.12.2
• 空间Pandas :0.4.7
• 数据着色器:0.14.4
• NumPy:1.24.3

此外，由Poitriy1.4.2管理的是Python环境
