squidpy.gr.neighbors.GraphBuilderCSR

class squidpy.gr.neighbors.GraphBuilderCSR(transform=None, set_diag=False, percentile=None, postprocessors=())

CSR-based graph construction strategy.

Specializes GraphBuilder for sparse CSR matrix output. Adds SparseEfficiencyWarning suppression and multi-library library_key combination. Built-in concrete builders (KNNBuilder, RadiusBuilder, DelaunayBuilder, GridBuilder) inherit from this class and declare their postprocessors explicitly in __init__ using the reusable public postprocessor classes.

Subclass this (not the generic GraphBuilder) when implementing a builder that returns CSR matrices.

Methods

build(coords)
build_graph(coords)	Construct raw adjacency and distance matrices.
