The scipy/__init__.py file exposes almost everything that
numpy/__init__.py does, but it replaces some of the math functions
with some alternate versions from numpy.lib.scimath. The reasons for
this are historical and shouldn't concern you. If you want those
versions, import them from numpy.lib.scimath yourself.
If you need stuff from numpy, import it from numpy. If you need stuff
from a scipy subpackage (e.g. from scipy.special), import it from that
subpackage. Never just do "import scipy".
