Hi,

Hi

I get numpy errors after I install Picalo (www.picalo.org http://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. http://1.0.4. distributed with Scipy superpack (http://macinscience.org/?page_id=6)

Could anyone please help?

The problem is that numpy was build using a python that was build with ucs4 (it is a unicode thing) while the python you run (I assume the Apple one) is ucs2. To fix this either build your own numpy or get a binary one that is ucs2, but I have no clue where one would get such a thing.

Thanks, and cheers Igor

Cheers, Michael

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?
