This was it, I now get:

>>> import os, psutil
>>> psutil.Process(os.getpid()).get_memory_info().rss / 1e6
20.324352
>>> %time import numpy
CPU times: user 84 ms, sys: 464 ms, total: 548 ms
Wall time: 59.3 ms
>>> psutil.Process(os.getpid()).get_memory_info().rss / 1e6
27.906048

Thanks for the tip.
