Re: [Visualpython-users] problems with faces_ demos on 64-bit hardy

[Bruce S. <Bru...@nc...>]

With visual-3.2.9 you're using the older Numeric, not the newer numpy. 
It does seem plausible that there could be some problems with Numeric in 
a 64-bit environment, since it was developed and debugged long before 
64-bit computers were generally available. I don't know what would have 
to be changed to get around this problem (and I myself don't have access 
to a 64-bit machine).

It might be interesting to see what happens with the beta version of 
Visual, since it is based on numpy.
