I have updated my fork of sympy at github (brombo/sympy) and something
strange is happening in my imports.
The following is the result of a python terminal session (using my
updated sympy)
>>> from sympy.galgebra.ga import Ga
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name Ga
>>> import sympy.galgebra.ga as ga
>>> dir(ga)
['Add', 'Com', 'DD', 'Expr', 'Format', 'Function', 'GA_LatexPrinter',

>>>
The dir(ga) looks like the contents of an old version, but the class Ga
is in sympy.galgebra.ga in brombo/sympy
Please help? Can someone see the forest for the trees?
