We are delighted to announce the release of [Flux](https://github.com/FluxML/Flux.jl)`v0.10`. This is a huge release including the work of many contributors; the major development is that Flux now uses [Zygote](https://github.com/FluxML/Zygote.jl) as its default backend for gradients, removing many warts from Flux’s interface and making a much larger class of Julia programs differentiable by default. See the [news](https://github.com/FluxML/Flux.jl/blob/master/NEWS.md) file for more information on other changes.

To try it out, [get Julia 1.3](https://julialang.org/downloads/) and `]add Flux` (or `]up Flux` if you have a previous version installed already) from a REPL. Since this is such a big change, some breakage and regressions are inevitable; some users may want to `]add Flux@0.9` to keep to the stable current release. We’d love to have feedback on the experience through the usual channels.

We would like to thank everyone involved in helping with getting this far, through testing, issues and patches. Flux’s users have been doing some [really cool things](https://arxiv.org/pdf/1907.07587.pdf) with differentiable programming already, and we’d love to hear what folks are up to. Enjoy!

– Dhairya, Mike, and the Flux community

I’m trying out the second [example](https://fluxml.ai/Flux.jl/stable/models/basics/#Simple-Models-1) but the gradient doesn’t change if I change the loss function, seems a bit weird:

```julia
julia> gs[W]
2×5 Array{Float64,2}:
 0.567762 0.753178 0.520799 1.05333 0.337904
 3.84924 5.21601 3.50305 7.42851 2.15487

julia> function loss(x, y)
           ŷ = predict(x)
           1
       end
loss (generic function with 1 method)

julia> gs = gradient(() -> loss(x, y), params(W, b))
Grads(...)

julia> gs[W]
2×5 Array{Float64,2}:
 0.567762 0.753178 0.520799 1.05333 0.337904

Forgot to mention in the original post; we strongly recommend getting Julia 1.3 in order to use this release of Flux. Although we support earlier Julia versions, 1.3 has a fix for this exact issue, which can cause some confusion otherwise.

Thanks for the reminder @jonathanBieler!

Why not put a lower bound on the Julia version, or some warning and workaround in the docs at least ? Otherwise people are gonna get in trouble.

Since Julia 1.0 is the LTS release, we’re going to continue supporting it as far as possible; and this is really a usability issue rather than a functional one.

There is a note on the Zygote readme about this with a workaround for earlier versions, but I agree we should add a note to the docs.

Using Flux throws some CUDA related errors for me. I have Julia 1.3 on a Windows 10 machine without GPU.

Thank you! This is very exciting. 🚀

I wonder why you chose 0.10 as the name of the release instead of 1. 😄 Usually after 0.9, 1 comes not 0.10 (=0.1).

0.10 is not the same as 0.1, they just look similar (thanks to base-10 arithmetic). 1.0 should come when it’s the right time, not just because it just happens to look like there are no more numbers left 🙂

This at least an ignorant question, maybe stupid - in Julia 1.3, I type `]up Flux` and the output info looks as I’d expect.

However when typing `status` I still see `[587475ba] Flux v0.9.0` listed - so I guess it is not really updated? Am I missing something? _I also tried removing and then adding Flux again and it still list version 0.9_.

Also, is there a way to have Flux print its current version number?

Do you have, by chance, any packages installed that require an older version of `FFTW`? That was the problem for me, since that was holding back Zygote, which held back Flux. You can try `]add Flux@0.10`, then you should get an error message, telling you which packages cause problems. It’s not a great experience right now, debugging these problems, we really need a better solution in Pkg for this.

Thanks - the version specification (`add Flux@0.10`) is useful to know. I have the same issue as you with FFTW and Zygote.

As I understand your comment, there is some package that is requiring an old version of FFTW - is there a trick to find out what package that is?

It looks like FFTW is on version 1.1.0, but my installed version is 0.3.

Could you post the output you’re getting? As far as I know, there’s really no convenient way to check this, so for me it was more or less trial and error.

Try upgrading FFTW first or try run `add Flux@0.10 FFTW`

I did try to update FFTW, but it is stuck at 0.3. I just tried `add Flux@0.10 FFTW` and it gives the same output as I posted before 🙁

Ah, it took me a while but I just tried `add FFTW@1.1.0` and it tells me now that ArrayFire is the culprit.

I can delete ArrayFire for now, as I’m not using it too actively, but it was helpful for some cases (I’m testing a lot on a MacBook with Radeon Pro 555X not nVidia).

any good suggestions for simple access to GPU to replace ArrayFire?

I did [https://gist.github.com/KristofferC/7c8048e2ee9aaa465966caeb98c1446a#file-packages\_holding\_back-md](https://gist.github.com/KristofferC/7c8048e2ee9aaa465966caeb98c1446a#file-packages_holding_back-md) a while ago and indeed, ArrayFire is shown to hold back FFTW.
