As I see, you use Manjaro, right? Manjaro, as based on Arch Linux distributive, uses rolling release scheme - for providing latest program versions. So, I suppose, that your sympy packages have been updated recently, but without proper Octave (Sage) updates. It actually, typical problem of Manjaro - problems with packages like that (and the reason for stable distros like Ubuntu LTS to exists). So, the problem is that, then you run `syms x` Octave (or Sage), as SymPy user, try to use attribute `integer_types` from `sympy.core.compatibility`, but the attribute was deleted since SymPy 1.6 , so Octave code for using sympy have failed and module can't be used, so symobolic variable can't be created. I have recomend go to Octave/Sage bugtracker and report problem there, with this python trace message. Or you can just wait some days - I don't think, that you are the only user of symbolic packages, so maybe the problem already reported and will solved in near future sage/octave packages updates. -- You are receiving this mail because: You are watching all bug changes.
