Hi,
I get numpy errors after I install Picalo (www.picalo.org) on Mac OS X
10.4.11 Tiger. I have tried to import numpy in Picalo using the instructions
in PicaloCookBook, p.101.
I get this error message which I don't understand.
Per Picalo author (see below for his reply to my email to Picalo discussion
forum), I try it here.

 I use numpy v. 1.0.4. distributed with Scipy superpack (
http://macinscience.org/?page_id=6)

Could anyone please help?
Thanks, and cheers
Igor

You're doing everything right from my perspective.  It looks like a problem
with NumPy.  The stack trace goes to multiarray.so in their core toolkit.  I
think you should hit their forums and see if they can help.

One idea is that Picalo uses unicode for all data values.  Perhaps numpy
can't handle unicode?
