I guess the problem does not arise in Python's namespace. Unless I'm
missing something, I don't see how 'import pytave' statement could
conflict with singular python modules or objects.
There seem to be an incompatibility between octave and singular shared
libraries (.so file) related to C++ templating. According to pytave's
dev, "The problem is conflicting implementations of Array<int>. Both
liboctave and Singular have their own template <class T> class Array
with an int instantiation". I thought it was impossible to simultenously
load the two .so files with the same python interpreter. Is it correct ?

Certainly, such name clashes are not uncommon (e.g. cvxopt defines its
own
matrix that clashes with Sage's matrix)
IMHO if you import the needed things from the package you need, doing
re-namings when needed, as usual (from foo import blah as fooblah)
you can avoid the problem you describe.

Hello,
I am still trying to use Pytave under Sage. After some work, I
eventually managed to compile every needed library (boost, octave), but
I went through an annoying bug.
It is possible to use the library with 'sage -python' or 'sage
-ipython' but when imported at the sage command prompt it fails.
According to pytave developper, it is due to an incompatibility between
the templates of octave and singular, the class Array ending up being
declared twice.
For this reason, I am wondering whether it is possible to restrict the
initial import into sage interpreter so as to avoid importing singular.
Would something usable remain if I remove all modules depending on it (I
don't really need pure mathematics functions anymore) ? What would be
the right way to do it ?
Best,
Pablo
P.S. the attempts I made are tracked
herehttps://bugs.launchpad.net/pytave/+bug/578767. Once it is done I would
be more than happy to contribute doc/script on the matter.
