That was merged. Still Cython and gmpy are being imported. Cython at least
should be

I thought Numpy was imported in more places by default. It may have been

Looks like numpy matplotlib are the main culprits of import slowness
after all. On my machine, after clearing the disk cache, I get:

I forgot that mpmath uses gmpy too. It's probably a waste of time to worry
about it then. Plus the polys use it heavily. If either of the libraries

I think numpy is used in more than just plotting by the way (you can put a

Sorry for being imprecise. When I was talking about numpy, I was referring
to the code sympy imports by default. numpy is used in several other

In order to get an objective test, it is probably a good idea to look at
the import time after clearing the disk cache. Under Linux, this can be
done

If you import SymPy in a clean environment (i.e., a virtualenv or something
similar), and compare it against your normal environment, you can see how

Any idea how to cleanly fix this? All the solutions I can think of are
very fragile. For example, if we just move all the imports inside methods
