Since I need the Flux#master version for my testing of package FluxModels.jl, I am facing trouble in updating/adding it. I updated GeometricFlux.jl but still there is some error I can’t resolve.

```julia
ERROR: Unsatisfiable requirements detected for package Flux [587475ba]:

 ├─possible versions are: 0.11.0 or uninstalled
 ├─Flux [587475ba] is fixed to version 0.11.0

The log says, that you want to install Flux master (versioned at 0.11) but GeometricFlux does not allow 0.11.

So until GeometricFlux is updated to handle Flux 0.11, you can’t upgrade Flux to beyond 0.10.

So unless you HAVE to have the latest version of Flux then you can just

```julia
]rm Flux
]up
]add Flux

```

I created a new env and now GeometricFlux supports Flux 0.11
