BSON.@save model_path * ".bson" model ERROR: type Method has no field ambig

[VoSiLk]

However, I get sometime weird errors when I try to save flux models. I'm not sure if it has some relation in which scope I would like to it. In other words, if I try to save in a script (global scope, it works) or in a function (function scope, it doesn't work).

push!(layers, Flux.Recur(Flux.LSTMCell(Float32.(W'), Float32.(U'), Float32.(b), (zeros(Float32, Int(length(b)/4),1), zeros(Float32, Int(length(b)/4),1))  )))

model = Chain(layers..., x -> reshape(x, :))

> model
Chain(Recur(LSTMCell(4, 80)), Recur(LSTMCell(80, 80)), Recur(LSTMCell(80, 80)), Recur(LSTMCell(80, 80)), Dense(80, 1, relu), #7)

I think you need literal strings too

[darsnack]

ambig issue was fixed in JuliaIO/BSON.jl#94. Do you have the latest BSON release?

[VoSiLk]

I worked on BSON v0.3.2. I now have tested it with v 0.3.3 and it works

[darsnack]

Just to clarify this means there is no error on BSON v0.3.3?

[VoSiLk]

yes no errror

[DhairyaLGandhi]

Cool!
