In case, one can in fact do this computation without the need to
swithing to GAP, as follows:
sage: libgap.LoadPackage("qpa")
....: Q=libgap.Quiver(3,[[1,2,"a"],[2,3,"b"]])
....: KQ=libgap.PathAlgebra(libgap.GF(3),Q)
....: KQ.AssignGeneratorVariables()
true
...
#I Assigned the global variables [ v1, v2, v3, a, b ]
sage: a=libgap.eval('a')
....: b=libgap.eval('b')
....: rel=[a*b]
....: KQ/rel
<GF(3)[<quiver with 3 vertices and 2 arrows>]/<two-sided ideal in
<GF(3)[<quiver with 3 vertices and 2 arrows>]>, (1 generators)>>
