Failure during testing

Thanks to Pearu's advice I have managed to get CVS SciPy built and installed on my Mac OS X (Jaguar) system. The problem is that most of my tests fail: Python 2.2 (#1, 07/14/02, 23:25:09) [GCC Apple cpp-precomp 6.14] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import scipy >>> scipy.test(level=1) No test suite found for scipy.__cvs_version__ creating test suite for: scipy.common !!

Traits: Problem with my first example.
by Donald 'Paddy' McCarthy May 25, 2003

May 25, 2003

Hi, I have just found out about traits and tried out the following example: ############ from traits import * class Person ( HasTraits ): __traits__ = { 'name': '', 'age': 9, 'weight': 0.0 } bill = Person() #bill.configure_traits( filename = None, edit = 1, traits = None ) bill.configure_traits( filename = 'xx.save', edit = 1 ) bill.edit_traits() ############# When run (Windows XP, wxwindows), the gui pops up as expected, but when I save my changes the program exits with the following error: C:\Documents and Settings\Paddy\My Documents>python -V Python 2.2.2 C:\Documents and Settings\Paddy\My Documents>python traitScript1.py 09:22:58: Debug: c:\projects\wx\src\msw\app.cpp(439): 'UnregisterClass(canvas)' failed with error 0x00000584 (class still has open windows.). Can you tell me what I am doing wrong? Also, the file of trait values generated is not editable text, is their a reason for this? Thanks., Paddy.

Help with solving an ODE
by Antonis Kaklis May 24, 2003

May 24, 2003

Hello to everybody I have the following problem I want to solve the differential equation y''(t) - beta * y'(t) + omega^2 * y(t) =F(t) F(t) is an external force with values stored in an external file in the form of "t, F(t)". How could I pass the values of F to the solver in order to solve the DE with scipy? Any suggestions? Please help Thanks in advance Antonis

SciPy on Mac OS X
by Andrew Nesbit May 21, 2003

May 21, 2003

Is anybody successfully using SciPy on a Mac OS X system? I'm currently up to the stage of trying to get LAPACK and ATLAS compiled, and it's turning out to be a fair amount of fuss. I'm doubtful it's even going to work and I don't want to waste too much time finding that out. Does anybody have any tips for getting SciPy built from source and working on my OS X system? In particular, it's the prerequisites that are causing most trouble at the moment. Thanks. Andrew.

Fwd: [Pythonmac-SIG] SciPy or ScientificPython
by Lance Boyle May 21, 2003

May 21, 2003

I hope that the pythonmac folks don't mind my forwarding the following post, and that it's not superfluous. Jack Jansen has done enormous amounts of great work for Python on the Mac, and he (I think it's his work) has made a nifty Python package installer. He (and we) could benefit from a bit of help getting SciPy to install using his installer. I wonder if someone from this list would like to get in touch with him. Here is a bit of a thread from pythonmac list. Jerry Begin forwarded message: > From: Jack Jansen <Jack.Jansen(a)cwi.nl> > Date: Tue May 20, 2003 02:33:31 America/Phoenix > To: "Lizardo H. C.M.
