How is this different from [No gradient is calculated during Flux training with ODE](https://discourse.julialang.org/t/no-gradient-is-calculated-during-flux-training-with-ode/42455)?

Thanks for the reply.  
Yes, they are the same issue. There was no reply in that post, so I simplify the code and post here, requesting for more possible attention.  
I’d be grateful if you could kindly provide any insight. This problem has bothered me for a while. Thanks

I have further simplified the code: [The tracked parameters are not updated during Flux.training](https://discourse.julialang.org/t/the-tracked-parameters-are-not-updated-during-flux-training/42507/1)

I’ve also requested to delete this post.

It would probably be easier to open one issue to track all of these simplifications.

[https://github.com/SciML/DiffEqFlux.jl](https://github.com/SciML/DiffEqFlux.jl)

Let’s get an issue open and I’m going to ping Flux developers for some help.
