Engine· classmethod

Engine.load

opens a saved project and returns an engine

Python

Engine.load(path, *, event_bus=None, workspace=None) -> Engine

Returns Engine — the restored engine, with entities and cached outputs reattached

Parameters#

name	type	default	description
`path`	`str`	—	the `.lsd` file (or JSON) written by `save`
`event_bus`	`EventBus \| None`	`None`	bus to attach; a fresh one is created when omitted
`workspace`	`str \| None`	`None`	override the stored workspace path

Example#

Python

from lsdtools import Engine

engine = Engine.load("survey.lsd")
engine.run_all(resume=True)

Notes#

Loads the project's declared packages first, so every step/entity class is registered before deserialization. Reattaches persisted step outputs, so cached results are reused without re-running. The workspace override lets a host define a project by where its .lsd file lives (portable, and sibling projects in one folder share input data).
