[Octave-bug-tracker] [bug #46771] symbolic/sympy oct-package fails

[anonymous]

Follow-up Comment #8, bug #46771 (project octave):

done with :

>> sympref IPC system
Resetting the octsympy communication mechanism
Forcing the system() octsympy communication mechanism
>> syms x

OctSymPy v2.2.4: this is free software without warranty, see source.
Using system()-based communication with Python [sysoneline].
Warning: this will be *SLOW*.  Every round-trip involves executing a
new Python process and many operations involve several round-trips.
>> f=x^2

f = (sym)

   2
  x
>> fi=int(f,x)

I think the octave version is 4.0.0. Should I try another one?
