class real_robot.utils.multiprocessing.utils.SharedObjectDefaultDict

Bases: dict

This defaultdict helps to store SharedObject by name (only known at runtime) so we don’t need to frequently create SharedObject

real_robot.utils.multiprocessing.utils.signal_process_ready() → None

When called, signals that the current child process is ready

by triggering SharedObject “proc_<pid>_ready”

real_robot.utils.multiprocessing.utils.start_and_wait_for_process(process: Process, *, timeout: float = 30) → None

Start and wait for a child process to be ready (finishes initialization) When the waiting process is ready, it should trigger SharedObject “proc_<pid>_ready”

Parameters:

• process – mp.Process

• timeout – If process is not ready after timeout seconds, raise a TimeoutError
