Presumably, you are using exp() from the builtin module math, which knows 
nothing about Numeric. Use Numeric.exp() instead.

I do recommend upgrading to numpy and asking further questions on the numpy 
mailing list.

When reporting an error, please include the smallest *complete* snippet of code 
that demonstrates the problem, as well as the complete traceback.
