BaseQuantumGraph

class lsst.pipe.base.quantum_graph.BaseQuantumGraph(header: HeaderModel, pipeline_graph: PipelineGraph)

Bases: ABC

An abstract base for quantum graphs.

Parameters

headerHeaderModel

Structured metadata for the graph.

pipeline_graphpipeline_graph.PipelineGraph

Graph of tasks and dataset types. May contain a superset of the tasks and dataset types that actually have quanta and datasets in the quantum graph.

Attributes Summary

bipartite_xgraph	A directed acyclic graph with quantum and dataset nodes.
datasets_by_type	A nested mapping of all datasets, keyed first by dataset type name and then by data ID.
quanta_by_task	A nested mapping of all quanta, keyed first by task name and then by data ID.
quantum_only_xgraph	A directed acyclic graph with quanta as nodes and datasets elided.

Attributes Documentation

bipartite_xgraph

A directed acyclic graph with quantum and dataset nodes.

Notes

Partial loads may not fully populate this graph, but it can always be accessed.

Node state dictionaries are described by the QuantumInfo and DatasetInfo types (or a subtypes thereof). Edges have state dictionaries described by BipartiteEdgeInfo.

The returned object is a read-only view of an internal one.

datasets_by_type

A nested mapping of all datasets, keyed first by dataset type name and then by data ID.

Notes

Partial loads may not fully populate this mapping, but it can always be accessed.

The returned object may be an internal dictionary; as the type annotation indicates, it should not be modified in place.

quanta_by_task

A nested mapping of all quanta, keyed first by task name and then by data ID.

Notes

Partial loads may not fully populate this mapping, but it can always be accessed.

The returned object may be an internal dictionary; as the type annotation indicates, it should not be modified in place.

quantum_only_xgraph

A directed acyclic graph with quanta as nodes and datasets elided.

Notes

Partial loads may not fully populate this graph, but it can always be accessed.

Node state dictionaries are described by the QuantumInfo type (or a subtype thereof).

The returned object is a read-only view of an internal one.
