spatialvi.model.base.SpatialNeighborhoodMixin

class spatialvi.model.base.SpatialNeighborhoodMixin

Mixin for spatial neighbor graph computation.

Applied to: SCVIVA, ResolVI. Provides a single entry point for neighbor graph computation with pluggable backends (squidpy on CPU, RAPIDS on GPU).

The computed neighbor arrays are stored in: - adata.obsm["index_neighbor"] — dense int array, shape (n_cells, n_neighs) - adata.obsm["distance_neighbor"] — dense float array, shape (n_cells, n_neighs)

These keys match the upstream ResolVI module’s expected input format.
