Are spatialpandas and antimeridian optional dependencies?

[tomvothecoder]

Hello, I'm going through the Visualizing Grid Topology notebook in the documentation.

I tried to run grid.plot but get ModuleNotFoundError: No module named 'spatialpandas'.

File ~/miniforge3/envs/xcdat_test_uxarray/lib/python3.12/site-packages/uxarray/grid/geometry.py:134, in _build_geodataframe_with_antimeridian(polygon_shells, antimeridian_face_indices)
    131 """Builds a ``spatialpandas.GeoDataFrame`` including any faces that cross
    132 the antimeridian."""
    133 # import optional dependencies
--> 134 from spatialpandas.geometry import MultiPolygonArray
    135 from spatialpandas import GeoDataFrame
    137 polygons = _build_corrected_shapely_polygons(
    138     polygon_shells, antimeridian_face_indices
    139 )

ModuleNotFoundError: No module named 'spatialpandas'

I assumed that uxarray would include spatialpandas since the Installation page doesn't list optional dependencies. However, I see that the conda recipe doesn't list spatialpandas and the stack trace says it is an optional dependency (line 133 above).

I'm just making sure if I should install spatialpandas alongside uxarray. Thanks!

I installed spatialpandas and now get the same error for antimeridian.

File ~/miniforge3/envs/xcdat_test_uxarray/lib/python3.12/site-packages/uxarray/grid/geometry.py:149, in _build_corrected_shapely_polygons(polygon_shells, antimeridian_face_indices)
    148 def _build_corrected_shapely_polygons(polygon_shells, antimeridian_face_indices):
--> 149     import antimeridian
    150     from shapely import polygons as Polygons
    152     # list of shapely Polygons representing each face in our grid

ModuleNotFoundError: No module named 'antimeridian'

I also see this GitHub issue reference the same things: #461 (comment)

Hi @tomvothecoder

Both of those modules are indeed required. I'll look into getting the recipe fix.

Thank you for catching this!

No problem! Thanks for the quick response @philipc2!
