[bug#47350] [PATCH 00/29] Add Zygote (piece for Machine Learning with Julia)

[zimoun]

Hi,

This adds all the packages required to build Zygote, the source-to-source
automatic differentiation in Julia.

   <https://github.com/FluxML/Zygote.jl>

It is the first brick to have Flux, the Julia machine learning framework.

  <https://github.com/FluxML/Flux.jl>

Noting that (at least 3) large pieces are still missing: Juno, Documenter and
CUDA.

Speaking about the Julia package CUDA, it is required by the test suite of
Zygote, that's why the #:tests? is #f.  However, we manually check the package
by running the small examples, e.g.,

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix environment -C --ad-hoc julia julia-zygote -- julia
julia> using Zygote
[ Info: Precompiling Zygote [e88e6eb3-aa80-5325-afca-941959d7151f]

julia> f(x) = 5x + 3
f (generic function with 1 method)

julia> f(10), f'(10)
(53, 5)

julia> @code_llvm f'(10)

;  @ 
/gnu/store/5m6676w77bbz44prbfxhxmk88srgxy81-profile/share/julia/packages/Zygote/src/compiler/interface.jl:62
 within `#43'
define i64 @"julia_#43_2036"(i64) {
top:
  ret i64 5
}

julia>  W, b = rand(2, 3), rand(2);

julia> predict(x) = W*x .+ b;

julia> g = gradient(Params([W, b])) do
         sum(predict([1,2,3]))
       end
Grads(...)

julia> g[W], g[b]
([1.0 2.0 3.0; 1.0 2.0 3.0], 2-element Fill{Float64}: entries equal to 1.0)
--8<---------------cut here---------------end--------------->8---

All the packages are not archived because of the rate limit.  They should be 
soon.

Last, well, I feel motivated to implement an (recursive) importer, even
inaccurate, it will greatly help.


All the best,
