I have added a patch that fixes this, available at: http://trac.sagemath.org/sage_trac/raw-attachment/ticket/6542/trac_6542_tachyon_tostr.patch
Since tachyon is currently broken on all systems in sage-4.1, I fixed the immediate problem rather than taking the time to improve the testing of tachyon.py. That is now trac ticket #6542: http://trac.sagemath.org/sage_trac/ticket/6542 If anyone has already started fixing the coverage of the tachyon.py files, please let me know so I don't duplicate effort. -Marshall Hampton On Jul 16, 6:50 am, Marshall Hampton <hampto...@gmail.com> wrote: > Works OK for me on a mac running 4.0.1, but doesn't work on sagenb > running 4.1, so I would guess this is an issue with 4.1. > > I have made this trac ticket > #6542:http://trac.sagemath.org/sage_trac/ticket/6542 > > -Marshall Hampton > > On Jul 16, 5:44 am, Paul Sargent <psa...@gmail.com> wrote: > > > Hi all, > > > I've just tried to re-run an old worksheet that uses Tachyon to > > raytrace an image.
