Error with delaunay=True

[Thapeachydude]

Hello,

I'm running into an issue in the very first step sq.gr.spatial_neighbors, whenever delaunay is set to True.

sq.gr.spatial_neighbors(adata = anndata, spatial_key = "spatial", coord_type = "generic", percentile = 99, n_neighs = 15, library_key= "sample") works, but sq.gr.spatial_neighbors(adata = anndata, spatial_key = "spatial", coord_type = "generic", percentile = 99, delaunay = True, library_key= "sample") crashes.

The full error message:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

I'm used to doing single-cell analysis in R but haven't had much python exposure, so any insights would be much appreciated.
Thanks!
