Dear Julia community,
I am trying to save parameters for trained RNN with BSON. However it seems that in latest version of FLUX this is not possible, however [https://fluxml.ai](https://fluxml.ai) says something different.
I create rnn as:
rnn = Chain(LSTM(12, 128), LSTM(128, 10), Dense(10, 1, relu))
then, create a parameters:
ps = params(rnn)
then trying to save parameters:
@save “param.BSON” ps
Here I get an error:
julia\> @save “param.BSON” ps
ERROR: UndefRefError: access to undefined reference
Anybody has an idea how to get out of this?
Julia Version 1.2.0
BSON v0.2.4
Flux v0.10.0

Have you try saving the result of `data.(ps)`? Though `data` is said to be deprecated, so It effectively seems like the docs needs an update!

Why not just save the model?
```julia
julia> @save "model.bson" rnn
```

This is exactly what I was looking for, thanks.
