Or maybe a feature? In normal python + numpy

import numpy.random as random random.RandomState(22)

works as expected, whereas in sage, the input has to be an array (e.g. [22]). Anyone know why?

This is because numpy does not recognize Sage integers as scalars. This is arguably a bug in numpy (since it is checking for scalars by looking at the type, rather than trying to coerce to an integer using the standard python functions to do so). A workaround is to use int(22) or 22r (i.e., a 'raw' 22) instead.
