I’m new to julia (as of last week; toyed a bit long time ago with v0.2). I’ve looked over previous Knet posts, searched docs, and Knet (stable) source but can’t find an example of saving/loading a model.
I see what look like some examples of loading or saving a model, but in the knet source these are in the deprecated directory… for example `model = gpucopy(load(opts["modelfile"],"model"))` in [Knet predict.jl deprecated example](https://github.com/denizyuret/Knet.jl/blob/1ef934cc58f9671f2d85063f88a3d6959a49d088/examples/deprecated/ipa/predict.jl#L14) … or this in the deprecated s2s.jl `# todo: implement load/save: revive cpucopy - done`
Could someone point me to an example or help me with how one saves and loads an pre-trained model?
What I’m trying to do: I’m evaluating julia for use in my company. Ideally I’d like to build ML/DL models and provide a backend “prediction” API… doing all of that in 1 language would be awesome!
One option is to build the graph (and likely train) in python-tensorflow then use go-tensorflow (maybe to train, definitely to serve the model) with go http server.
I’t might also be cool to see if I could build in Knet (or flux) and see if I could somehow serve the model from go (my understanding though is that would not be straightforward).

They are using the JLD.jl library. I would instead suggest using JLD2.jl
[https://github.com/simonster/JLD2.jl](https://github.com/simonster/JLD2.jl)
It’ll save pretty much anything. But one thing to remember is you have to `using KNet` before loading in order for it to know how to rebuild the types.

sweet, thanks. Gonna check it out. I’m thrilled (and a bit overwhelmed) at the number of projects in julia’s ecosystem. Just got done scanning down the list of packages in JuliaML… 😲
