Mark Hammond says he is unable to support all other packages and does
not include NumPy. So I had to keep with the last version which is in
Python win delivery b4 and b5. b6 is without, and not so stable by now.

If you have the MS c compiler which Mark uses, you can try to build it.
I don't know if this is difficult, at least it is a welcome 
contribution ;^)

Look at your PythonPath, it should contain NumPy by default. If not,
then you had something wrong at installation time.
The registry contains a key for every package that gets its own path.
You might watch it with regedit:
HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\1.4.0\PythonPath
It must contain a key "Numeric" and a 
standard value of e.g. "E:\Python\NumPy"
Look for the others there and do it analoguous.
If you don't have registry entries at all, then you have a totally
outdated Pythonwin. _do_ _not_ use any binaries from the Pysthon
CD-s, they are definately out of date.

Despite the above, it would not hurt to say
Numeric = NumPy.Numeric
x = Numeric.array([1,2,3])

This one works:
import ni, Numeric
from Numeric import FFT

The same does not work for (this version of) MLab, because it falsely
includes "from Numeric import *" which is again not ok for "ni".
You might change that or look for another version. I think this was
in an early state.

ok?
