Geopandas pygeos seems absent, yet has already been installed

[sarahlunette]

When doing df = gpd.GeoDataFrame(df1, crs = 'EPSG:4326', geometry = geopandas.points_from_xy(df1.longitude,df1.latitude)) I get "name 'pygeos' is not defined", yet I have installed pygeos in the directory where I dev and

python3.9/site-packages/geopandas/_vectorized.py in points_from_xy(x, y, z) 247 248 if compat.USE_PYGEOS: --> 249 return pygeos.points(x, y, z) 250 else: 251 out = _points_from_xy(x, y, z)

and import pygeos is in the script. Is there a specific way to well install pygeos in order to avoid such error ? Thanks
