fwi_2D_small_overthrust_lbfgs.jl software papers example

[scott314159]

I tried to run fwi_2D_small_overthrust_lbfgs.jl and got the following error:
#############################################################
ERROR: LoadError: MethodError: no method matching optimize(::Opt, ::PhysicalParameter{Float32, 2})

Closest candidates are:
optimize(::Opt, ::AbstractVector{<:Real})
@ NLopt ~/.julia/packages/NLopt/w0c7n/src/NLopt.jl:634
###############################################

I the issue seems to come from line 66:
(minf, minx, ret) = optimize(opt, copy(model0.m))

I found a different example which has optimize syntax:
(minf, minx, ret) = optimize(opt, vec(model0.m.data))

Which seems to work but I am not sure if this is the appropriate fix.

vec(model0.m.data)). is fine yes, looks like some type mismatch that is now popping up with the PhysicalParameter
