Unused arguement error while tuning

[TheMadHatter666]

The problem

I cannot seem to tune with H20, I keep getting an "unused argument" error. I was using an example that used keras (which works fine) and I just switched the engine from keras to h2o and thought it should also work. But it didn't.

To track it down, I decided to run the code from https://agua.tidymodels.org/articles/tune.html

which is given below:

copied R code

library(tidymodels)
library(agua)
library(ggplot2)
theme_set(theme_bw())
doParallel::registerDoParallel()
h2o_start()
data(ames)

set.seed(4595)
data_split <- ames %>%
  mutate(Sale_Price = log10(Sale_Price)) %>%
  initial_split(strata = Sale_Price)
ames_train <- training(data_split)
ames_test <- testing(data_split)
cv_splits <- vfold_cv(ames_train, v = 10, strata = Sale_Price)

ames_rec <-
  recipe(Sale_Price ~ Gr_Liv_Area + Longitude + Latitude, data = ames_train) %>%
  step_log(Gr_Liv_Area, base = 10) %>%
  step_ns(Longitude, deg_free = tune("long df")) %>%
  step_ns(Latitude, deg_free = tune("lat df"))

lm_mod <- linear_reg(penalty = tune()) %>%
  set_engine("h2o")

lm_wflow <- workflow() %>%
  add_model(lm_mod) %>%
  add_recipe(ames_rec)

grid <- lm_wflow %>%
  extract_parameter_set_dials() %>%
  grid_regular(levels = 5)

ames_res <- tune_grid(
  lm_wflow,
  resamples = cv_splits,
  grid = grid,
  control = control_grid(save_pred = TRUE,
    backend_options = agua_backend_options(parallelism = 5))
)

ames_res

The output is :

10-fold cross-validation using stratification

There were issues with some computations:

• Error(s) x10: Error in fn(...): unused arguments (metrics_info = list(c("rmse", "rsq"), c("minimiz...

Run show_notes(.Last.tune.result) for more information.

Follow up on the suggestion

If I run show_notes …, this is the output:

if (sum(relevant_breaks) >= (n - 2)) {
return(breaks)
}
while (by > 1) {
by <- by - 1
breaks <- base^seq(min, max, by = by)

Just confirmed that this issue is fixed in the developmental version of the package via #52. For now, you'll need to install the developmental version of the package with pak::pak("tidymodels/agua") until we can get a new release of the package on CRAN!
