Delete Python module from disk after import while keeping it available in memory? The root of the problem is that the `start` method of a `multiprocessing.Process` instance sets its `_popen` instance attribute to a `multiprocessing.popen_*.Popen` instance. I tried the object detection example and i get below error: File "c:\continuum\anaconda3\Lib\multiprocessing\reduction.py", line 60, in dump ForkingPickler (file, protocol).dump (obj) TypeError: can't pickle _thread.RLock objects Could you please help. Thus if a `multiprocessing.Process` instance holds a reference to a started `multiprocessing.Process` instance then it holds a weak reference (point 2), so starting it will fail since it will serialise (point 1) the weak reference and weak references are not serialisable: ``` import multiprocessing if __name__ == '__main__': Get elements of list only with a certain distance between items? Serialization is an effective way to share big objects easily without losing information. JavaScript is disabled. Maybe it's a silly error on my part.
