Get size of Python object recursively to handle size of containers within containers

getsizeof_recursive.py

##### Taken from https://github.com/bosswissam/pysize

import sys

def get_size(obj, seen=None):
    """Recursively finds size of objects"""

    size = sys.getsizeof(obj)
    if seen is None:
        seen = set()

    obj_id = id(obj)
    if obj_id in seen:
        return 0

    # Important mark as seen *before* entering recursion to gracefully handle
    # self-referential objects
    seen.add(obj_id)

    if isinstance(obj, dict):
        size += sum([get_size(v, seen) for v in obj.values()])
        size += sum([get_size(k, seen) for k in obj.keys()])
    elif hasattr(obj, '__dict__'):
        size += get_size(obj.__dict__, seen)
    elif hasattr(obj, '__iter__') and not isinstance(obj, (file, str, bytes, bytearray)):
        size += sum([get_size(i, seen) for i in obj])

    return size

Thanks for the code.
I believe the file in L25 is supported only for Python2? Removing that works on Python3+.

However, I eventually went with this package, which turned out to be pretty neat too!

Thanks for sharing this snippet. I used it today here: https://discuss.ray.io/t/memory-issue-debugging/7573/5
