LoadError: UndefVarError: #flatten not defined

I think I messed with my installation of AlphaZero, and I can't recollect exactly how this occurred.

When launching a training, I get the following error:

Loading environment from: sessions/bonbon-rectangle-128_train

ERROR: LoadError: UndefVarError: #flatten not defined

If I Google UndefVarError: #flatten not defined, I get in the release notes of the Flux.jl package that its recent version 0.13.14 fixed this issue: https://github.com/FluxML/Flux.jl/releases.

However, this version seems to be incompatible with AlphaZero.jl. Indeed, if I modify the file Project.toml in my customized version of AlphaZero.jl in order to update the Flux package to the 0.13.14 version, I get the following error:

ERROR: Unsatisfiable requirements detected for package cuDNN [02a925ec]:

         └─AlphaZero [7a1cc850] is fixed to version 0.5.4

Maybe because that version of Flux requires a version of CUDA which is incompatible with AlphaZero restrictions?

I don't know how to move forward.
