I am new to the tidymodels package. I was trying to understand how to fine tune many models and I found an example. I was running it and then at this step,
grid_ctrl <-
control_grid(
save_pred = TRUE,
parallel_over = "everything",
save_workflow = TRUE
)
grid_results <-
all_workflows %>%
workflow_map(
seed = 1503,
resamples = concrete_folds,
grid = 25,
control = grid_ctrl
)
The code keeps running and after one hour and a half of running, I get finally the results with the following messages:
x The workflow requires packages that are not installed: 'ranger'. Skipping this workflow.

Is that normal that it takes so much time for running? I know there are 12 models for tuning and evaluating but I don't expect that it takes a lot of time.
