AttributeError: 'DataFrame' object 在使用 geopandas 时没有属性 'crs'

Question

我在使用 geopandas 和 shapely 时遇到错误

AttributeError: 'DataFrame' object has no attribute 'crs'

下面是代码：

#geometry = [Point(xy) for xy in zip(complete_major_accidents['longitude'], complete_major_accidents['latitude'])]
#crs='none'
geometry = gpd.points_from_xy(complete_nonmajor_accidents.longitude, complete_nonmajor_accidents.latitude)
world = gpd.read_file(gpd.datasets.get_path('naturalearth_lowres'))
#geometries = world['geometry'].apply(lambda x: x.wkt).values
#print(geometries)
#print(tuple(geometry))
gdf = GeoDataFrame(complete_major_accidents,  geometry)
gdf


ax = world[world['name'] == 'United Kingdom'].plot(figsize=(15, 15))
#print(type(ax))
gdf.plot(ax = ax, marker='o', color='red', markersize=15, edgecolor='black')
#gdf.plot(ax=world.plot(figsize=(15, 15)), marker='o', color='red', markersize=15)

AttributeError: 'DataFrame' object has no attribute 'crs'

Answer 1

我终于可以通过更改下面的代码来解决它

gdf = GeoDataFrame(complete_major_accidents,  geometry)

至

gdf = GeoDataFrame(complete_nonmajor_accidents,  geometry = geometry)

Answer 2

从旧版本更新 Geopandas 后，我遇到了同样的错误。 以下修复成功了。

self.ax = gpd.GeoDataFrame().plot(figsize=(18, 12))

至

self.ax = gpd.GeoDataFrame(geometry=[]).plot(figsize=(18, 12))
