Enzyme Documentation example does not work on CPU

[aquaresima]

The example:

using Flux
using Enzyme

model = Chain(Dense(28^2 => 32, sigmoid), Dense(32 => 10), softmax);
dup_model = Duplicated(model);

x1 = randn32(28 * 28, 1) ;
y1 = [i == 3 for i in 0:9];
grads_f = Flux.gradient((m, x, y) -> sum(abs2, m(x) .- y), dup_model, Const(x1), Const(y1))

output this text and return this error:

Internal error: during type inference of
(::Type{EnzymeCore.Duplicated{T} where T})(Flux.Chain{Tuple{Flux.Dense{typeof(NNlib.σ), Array{Float32, 2}, Array{Float32, 1}}, Flux.Dense{typeof(Base.identity), Array{Float32, 2}, Array{Float32, 1}}, typeof(NNlib.softmax)}})
