I developed a stacked ensemble model using the tidymodels workflow and I want to monitor the performance of this model from time to time using vetiver. However, it seems the stacked model object isn't supported yet.

Please see the code snippet below

library(tidymodels)
library(vetiver)
library(pins)
library(arrow)
library(tidyverse)
library(bonsai)
library(stacks)
library(lubridate)
library(magrittr)



b <- board_folder(path = "pins-r/")
model <- vetiver_pin_read(board = b, name = "dcp_ibese_truck_arrival", 
                      version = "20230110T094207Z-69661")

trips <- read_parquet("../IbeseLivePosition/ml_data/data_to_monitor_model.parquet")

trips %<>%
  mutate(Date = as.Date(DateTimeReceived))

original_metrics <- 
  vetiver::augment(model, new_data = trips)

Error: No augment method for objects of class butchered_linear_stack

  • Please provide enough code so others can better understand or reproduce the problem. – Community Jan 11 '23 at 14:19

    Looks like stacks doesn't yet have `augment` methods; I have [opened an issue here](https://github.com/tidymodels/stacks/issues/173) to track this feature. – Julia Silge Jan 11 '23 at 17:29
