Warning message about package emoa not being installed

[ledell]

I got a warning about not having the emoa package installed; not sure if this is a real issue or not. Just posting here for reference, in case not having it installed changes/hurts the results (if it's required for hyperband?).

Thanks for the report! This was an issue with mlr3hyperband and should be fixed with this commit: https://github.com/mlr-org/mlr3hyperband/commit/95a17182ed4129d99dc544aa4bbeebaa204fd210

Try to update mlr3hyperband like so:

devtools::install_github("mlr-org/mlr3hyperband@95a17182ed4129d99dc544aa4bbeebaa204fd210")

This should fix the warning (we did not need emoa anyway, it is only used for multi-crit optimisation). Let me know if it helps

That fixed it, thanks!
