I'm going to take a wild-ass guess and suggest that was a concious decision by the authors. Shadowing builtins is generally a no-no. You just need to be explicit instead of implicit:
from numpy import min, max
I see. But why by default sum is exported? Is that a wise decision?
In [1]: from numpy import *
In [2]: help sum ------> help(sum) Help on function sum in module numpy.core.oldnumeric:
sum(x, axis=0, dtype=None) ...

Zhang: The reason max and min are not imported by 'from numpy import *' is because there are no such functions in numpy. They are ndarray methods now (a.max(), a.min()), there is also a maximum and minium function which behaves somewhat differently. There is still a sum function as you have discovered, and it will clobber the builtin. Another good reason not to use 'from numpy import *' -Jeff -- Jeffrey S.
