Remove the gpu() functions if not needed

[ViralBShah]

IIRC, the gpu() functions are not needed any more and to run on GPUs, one only needs CuArrays. If so, can the notebooks be updated accordingly?

Also, should we register as a Julia package?

[MikeInnes]

You still need the call to gpu to actually transfer things there (if applicable).

Is it helpful for this to be a package? The main difference seems to be using add rather than git clone, but then you have to know how to find things in your package folder anyway.

Sorry - I just meant those gpu functions on the top of the notebook.

The other benefits of a package could probably be things like CI and an easy way to install, but not the most pressing point for now.

[MikeInnes]

Ah, got it – yeah these notebooks definitely need a refresh then.

I don't know if there's a canonical way to do CI for notebooks, but we could probably get something together with nbinclude or similar.

Is there any chance to find out in what versions were the Flux GitHub stuff written? Because most of it doesnt work for me even when i read readme files and just copy paste it...

Maybe PkgUtils.jl could be used here? Just saw this video the other day from JuliaCon: https://www.youtube.com/watch?v=LYVdRTuxS_c&t=1s
