Comment:
There is still a two-weight code left in
`graphs/strongly_regular_graphs_db`, namely, in
`SRG_729_336_153_156` there is matrix `L`, which gives
{{{
sage: [w for w,f in enumerate(LinearCode(L.T).weight_distribution()) if w
and f]
[108, 117]
sage: LinearCode(L.T)
Linear code of length 168, dimension 6 over Finite Field of size 3
}}}
