Unless you have a good reason to choose Numeric, such as some other  
package that requires it, NumPy is clearly the better choice. If you  
do use Numeric, please use version 23.8 rather than 24.x, as the  
latter doesn't work reliably with MMTK.

The choice between Numeric and NumPy is made when ScientificPython is  
installed. Use option --numeric or --numpy when running setup.py. The  
default is --numeric up to release 2.7.x, and --numpy starting with  
2.8. MMTK always uses the same package as ScientificPython. If you  
reinstall ScientificPython to switch to another package, you also  
have to reinstall MMTK.

Konrad.
