Using geodataframe

[mohdalattar]

Greetings,

I have a geodataframe. It is not clear to me how can I pass it to GeoGraph function to calculate landscape metrics

gdf = ox.geometries.geometries_from_place('Manhattan', tags={'leisure': ['park','garden', 'dog_park'],'landuse': ['grass','allotments','flowerbed','village_green']})
gdf = ox.projection.project_gdf(gdf)
gdf = gdf[gdf.geom_type == "Polygon"].reset_index(drop=True)

Even when I pass a shapefile I am getting an error message

test = GeoGraph('/Users/mohammadalattar/Downloads/Oo.shp')

File "", line 1, in
test = GeoGraph('/Users/mohammadalattar/Downloads/Oo.shp')

File "/Users/mohammadalattar/opt/anaconda3/lib/python3.8/site-packages/geograph/geograph.py", line 140, in init
self.df = self._load_from_vector_path(load_path)

raise ValueError("class_label must be a column in the dataframe.")

ValueError: class_label must be a column in the dataframe.

You need to make sure that class_label is a column in the dataframe indicating the landcover type, and that "geometry" is the column containing the geometries. This is necessary to ensure that GeoGraph can calculate landcover class level metrics.
