Ring.to_shapely not working

[philippjfr]

The to_shapely method on Ring geometries does not seem to work:

from spatialpandas.geometry import Ring

Ring([0, 0, 1, 1, 2, 0, 0, 0]).to_shapely()

---> 32         line_coords = self.data.to_numpy()
     33         return sg.LinearRing(line_coords.reshape(len(line_coords) // 2, 2))
     34

Thanks, I'll take a look

I'm on a machine I cannot test this, BUT I do have an idea on what might be happening...

to_numpy was added recently as I recall. I found a reference to version pandas-0.24.0. Try updating pandas and see if it still is an issue.
