Hello Everybody,

I am new in Julia and Flux. I went through model-zoo and it seems as pretty nice example. However as far I had no luck to make it work. After hours of googling and going through non-consistent information I would like to ask, if here is somebody who could recommend me right version of Julia and Flux I should use. Currently I have version of Julia “1.2.0” and Flux 0.10.0. However examples in model-zoo use Tracker what is not included in my version. What version then i should install to have Flux with Tracker? I found information that last stable version of Flux uses tracker but which version it is? Or is there any official compatibility table?

Thank you for response.

While I haven’t tried this, the model zoo has a Project.toml & Manifest.toml pair (and some models have their own). Can you try activating that, which should fix all required packages to what they were?

Over [here](https://github.com/FluxML/model-zoo/blob/master/Manifest.toml#L248) it looks like the main file uses Flux@0.9.0, which uses Tracker.

Model zoo needs a revamp, many scripts are not working, unfortunately. There are many open PR trying to push some updates but they are not receiving much attention

I suggest to stay on the latest Flux and Zygote released version, copy and run one of those scripts in the open PRs. For instance you could try with the mnist/mlp.jl script [here](https://github.com/FluxML/model-zoo/pull/187/files). Please also report back in the PR’s conversation if your attempt was successful or not.

[improbable22](https://discourse.julialang.org/u/improbable22): Check \*.toml files is good idea, thanks, it helps me to one step further.

[CarloLucibello](https://discourse.julialang.org/u/CarloLucibello): I did not see how many PRs are there. I will stick on them. Thanks for notify it.
