pretty_print(debug_init=False, debug_owners=False, trace_depth=5, output=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='utf-8'>) → None[source]
mantidimaging.core.utility.leak_tracker.find_owners(obj, depth: int, path: List[str] | None = None, ignore: Set[int] | None = None) → List[List[str]][source]

Recursively track though references to objects and return a list of routes
