RestoreIntermediatePass

class RestoreIntermediatePass(project_directory, load_blocks=True)

Bases: BasePass

__init__(project_directory, load_blocks=True)

Constructor for the RestoreIntermediatePass.

Parameters:

• project_directory (str) – Path to the checkpoint block files. This directory must also contain a valid “structure.pickle” file.

• load_blocks (bool) – If True, blocks in the project directory will be loaded to the block_list during the constructor. Otherwise the user must explicitly call load_blocks() themselves. Defaults to True.

Raises:

ValueError – If project_directory does not exist or if structure.pickle is invalid.

Attributes

name	The name of the pass.
