Hello,  
I’m trying to reproduce the anodes example on augmented neural ODEs from the thread [Fitting neural ODE to periodic time series](https://discourse.julialang.org/t/fitting-neural-ode-to-periodic-time-series/42263). However, when replacing Flux by the Lux library (with the corresponding changes) I get: `FromFluxAdaptor` requires `Flux.jl` to be loaded. I don’t have Flux added to Julia, and since I’m just starting to learn neural ODEs, I’m a bit lost here. Does anyone have any suggestions on how to modify the original code to use Lux instead of Flux?  
Thanks!

You just need to `using Flux` in order to use `FromFluxAdaptor`. Can you share the code you’re running?
