It would be helpful to see a 'minimal' example that one can just 'plug in'.
Ordinarily P.save should work fine.
My own puttering about led to this unfortunate mess.
sage: sage: var('u, v')
(u, v)
sage: sage: x = u
sage: sage: y = v
sage: z = u
sage: fc = sin(u)
sage: P =
parametric_plot3d([x,y,z],(u,-10.0,10.0),(v,-10.0,10.0),plot_points=[50,50],frame=False,color=(fc,colormaps.jet))<snip
expected deprecation warning>
rich_output = self._call_rich_repr(obj, rich_repr_kwds)
/Users/.../sage/local/lib/python2.7/site-packages/sage/repl/rich_output/display_manager.py:570:
RichReprWarning: Exception in _rich_repr_ while displaying object: the
number of arguments must be less than or equal to 1
RichReprWarning,
Graphics3d Object
the second warning was unexpected, the output REALLY is unexpected.
Volker (or someone else) what is going on here with the display hook -
shouldn't *some* graphic, even an empty one, show up here, even if my
made-up input makes no sense? Once after trying something like this,
Ctrl-C even led to a segfault, very impressive! This is in beta3; in Sage
6.5 it's the possibly even worse KeyError: 'text/plain'.
