It would be great if clearer warnings and guidelines could be offered on how to use custom metrics from yardstick with tuneparallel_over option? Personally, it took quite a while to figure out that the error message:
! no applicable method for 'mse' applied to an object of class "c('grouped_df', 'tbl_df', 'tbl', 'data.fram..
despite the script itself containing a mse <- function(data, ...) { UseMethod("mse")} call?
tune: emit a warning if parallel is used with custom metrics?
in general: provide guidelines on how to handle the problem? The solution in https://github.com/tidymodels/tune/issues/479 to write a specific package just for the function seems quite heavy?
