[with patch, in limbo] Fix deprecation warnings from numpy 1.2

Reported by: jason Assigned to: was
Priority: critical Milestone: sage-3.4
Component: linear algebra Keywords:
Cc:

Description

Apparently we use the numpy C API in the RDF/CDF vector classes, which causes deprecation warnings with numpy 1.2. This patch updates this code to use current functions in numpy 1.2.

Attachments

numpy-deprecations.patch (8.2 kB) - added by jason on 09/27/2008 03:12:26 AM.

Change History

09/27/2008 12:20:39 AM changed by jason

This patch depends on the patches at #3498. Both patches touch the numpy.pxd file, so this needs to be applied after the patches at #3498.

09/27/2008 12:22:15 AM changed by jason

sage -t sage/modules/*.pyx passes with the patch applied.

09/27/2008 01:19:36 AM changed by mabshoff

With #3498 and numpy-deprecations.patch applied we get some segfaults: 

sage -t -long devel/sage/sage/numerical/optimize.py # Segfault
sage -t -long devel/sage/sage/modules/real_double_vector.pyx # Segfault
sage -t -long devel/sage/sage/modules/complex_double_vector.pyx # Segfault

We need the following patch to quiet one deprecation warning:

[02:21am] jason-: comment from that line down to the end of the function

[02:24am] jason-: it's going to be really slow, but it works
[02:25am] mabshoff: well, I guess for now we can live with that.
[02:25am] jason-: well, I don't know how much slower

Hmm... what's up with 

-sage: from scipy import linsolve   
+sage: from scipy.sparse.linalg.dsolve import linsolve

in sage/numerical/test.py? Does scipy.linsolve not work anymore?

Also, those doctest failures look like more than trivial noise, but I have no experience in the area so someone else should comment.

  • summary changed from [with patch, needs review] Fix deprecation warnings from numpy 1.2 to [with patch, needs work] Fix deprecation warnings from numpy 1.2.
23:36 < mabshoff> #4205 isn't useful yet.
23:36 < wstein-4205> #4205 is scrwed up!
23:36 < wstein-4205> The thing says "needs review"
23:36 < wstein-4205> but it clearly "needs work".
23:37 < mabshoff> That one is more or less in limbo until we do the Scipy 0.7 update.
23:37 < mabshoff> Yep
23:37 < wstein-4205> And the patch itself just deletes *all* the C API code that Josh Kantor spent a *huge* amount
23:37 -!- craigcitro is now known as cc-4612
23:37 < wstein-4205> of time writing, and replaces it with a bunch of slow python numpy code.
23:37 < mabshoff> ok
23:37 < wstein-4205> Huh?
23:37 < wstein-4205> Or maybe I don't get it.
23:37 < mabshoff> Ask jason|log 
23:37 < wstein-4205> I'm changing it to "needs work".

Sorry; as is obvious from the discussion and iterative approach, this ticket is indeed "needs work"; I thought that was how it was marked. I think in the initial iteration, we thought we had something good, so it started out as "needs review" and then we forgot to change it to "needs work" when we started playing whack-a-mole.

11/27/2008 07:15:48 AM changed by jason

And mabshoff is right, it's on hold until scipy 0.7 is release soon.

  • summary changed from [with patch, needs work] Fix deprecation warnings from numpy 1.2 to [with patch, possibly not needed] Fix deprecation warnings from numpy 1.2.

In fact, this ticket may not be needed anymore if the patch from #4206 is applied.

  • summary changed from [with patch, possibly not needed] Fix deprecation warnings from numpy 1.2 to [with patch, in limbo] Fix deprecation warnings from numpy 1.2.

Some bits of this patch fix scipy import issues since things have moved around. Other than that I agree with Jason that we likely will end up canning the rest of this patch.

Cheers,

Michael
