sympy version?

[Doug Stewart]

I just upgraded to ubuntu 20.04.3

I compiled Octave  GNU Octave, version 7.0.91  3ca33008c4a9

And installed

     control *|   3.4.0 
    symbolic *|   2.9.0

I get errors when running a program that I wrote and it worked before.

Do I need a different sympy version?
