  In Gurau and Keppler 2022 (arXiv:2207.01993), a relation between orthogonal
and symplectic tensor models with quartic interactions was proven. In this
paper, we provide an alternative proof that extends to polynomial interactions
of arbitrary order. We consider tensor models of order D with no symmetry under
permutation of the indices that transform in the tensor product of D
fundamental representations of O(N) and Sp(N). We explicitly show that the
models obey the N to -N duality graph by graph in perturbation theory.
