Loading and Saving Models

Since models are just simple Julia data structures, it' s very easy to save and load them using any of Julia' s existing serialisation formats. For example, using Julia' s built-in
< code > serialize< / code >
:
< / p >
< pre > < code class = "language-julia" > open(io -> serialize(io, model), " model.jls" , " w" )
open(io -> deserialize(io), " model.jls" )< / code > < / pre >
< p >
One issue with
< code > serialize< / code >
is that it doesn' t promise compatibility between major Julia versions. For longer-term storage it' s good to use a package like
< a href = "https://github.com/JuliaIO/JLD.jl" >
JLD
< / a >
.
< / p >
< pre > < code class = "language-julia" > using JLD
@save " model.jld" model
@load " model.jld" < / code > < / pre >
< p >
However, JLD will break for some models as functions are not supported on 0.5+. You can resolve that by checking out
< a href = "https://github.com/JuliaIO/JLD.jl/pull/137" >
this branch
< / a >
.

Right now this is the only storage format Flux supports. In future Flux will support loading and saving other model formats (on an as-needed basis).
