PassManager

class PassManager(passes=None, max_iteration=1000, callback=None)[source]

Manager for a set of Passes and their scheduling during transpilation.

Initialize an empty PassManager object (with no passes scheduled).

Parameters

  • max_iteration (int) – The maximum number of iterations the schedule will be looped if the condition is not met.

  • callback (Optional[Callable]) – DEPRECATED - A callback function that will be called after each pass execution.

Deprecated since version 0.13.0: The callback parameter is deprecated in favor of PassManager.run(..., callback=callback, ...).
