When trying to load the converter form weave i got the following error:

sage: from scipy import weave            
sage: from weave import converters       
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

     19     pass
     20 
---> 21 from numpy.testing import ScipyTest
     22 test = ScipyTest().test

ImportError: cannot import name ScipyTest

And ...

sage: import weave                       
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

     22 test = ScipyTest().test

ImportError: cannot import name ScipyTest

What can i do?

The following should work:

sage: from scipy.weave import converters

Note that this is different from

sage: from scipy import weave
sage: from weave import converters

which gives the ImportError. The weave in from weave import converters does not refer to the module imported in from scipy import weave. Look at the following example:

sage: import scipy.weave as w2
sage: from w2 import converters
Traceback (most recent call last)
...
ImportError: No module named w2

I had this problem too, i was unable to compile sage 4.5.3 on Opensuse version 14 milestone 2. Mitesh's answer solved my problem.

well, doing export CC=icc;export CXX=icpc; sage -f python seems to work. at least, sage loads faster

or at least the sage's python?

ok, it uses qt4py which is an experimental package, so what kind of package it should be?

Today i saw this [http://kde-apps.org/content/show.php/...], and it looks cool doing numerical data 2d plots+interactive interface i.ve installed into sage and works fine, It uses PyQt4

is a convergence problem for l!=1.

like using ssh yea

from the terminal WHITOUT using a web browser? maybe using ssh?

i got it now, thanks

Thanks, your answer is very usefull

i have updated my question, its about doing f(a=1,b=2,c=3...)

what i do to do this?

sage: var('t w')
sage: f(t) = sin(w*t)
t |--> sin(t*w)
sage: w = 2
sage: f
t |--> sin(2*w)

Without doing f(w=2)!!! imagine that the function is f->f(a,b,c,d,f....,t) like doing this:

...
...
sage: aw1=aw1(m1=1,m2=0.5,l1=1,l2=0.5,g=9.8)
sage: aw2=aw2(m1=1,m2=0.5,l1=1,l2=0.5,g=9.8)
sage: aw4=aw4(m1=1,m2=0.5,l1=1,l2=0.5,g=9.8)
...
...

etc

thanks, :( thats exactly what i don't want. what if f->f(a,b,c,d,f....,t)? it would be a little annoying to do that.
