[NNParamsPrinter.jl](https://github.com/onedeeper/NNParamsPrinter.jl) is a lightweight, simple printer of NN parameters. This is all it does. Please check the GitHub readme for usage.

Why did I make this ?

I wanted to quickly see the weights of a simple NN in a readable way. My use case was in [universal differential equations](https://en.wikipedia.org/wiki/Neural_differential_equation). I had to write a small piece of code for it, which I thought others could benefit from, save them a few minutes 🙂

I hope it is useful in some way.

Thank you!

Cool! Do you think it can be contributed to Lux itself? 🙂

If you use [Experimental Features | Lux.jl Docs](https://lux.csail.mit.edu/stable/api/Lux/contrib#Lux.Experimental.layer_map) then you can extend your function to support all layers in a generic fashion

Thanks for the suggestions @Tortar and @avikpal ! I will work on these 🙂
