Tidymodels, processing through CPU vs. GPU

[pathos]

I was only able to find below two posts on this topic -- barely any conversation. Is there any support or documentation for tidymodels on using GPU?

GPU Support for boost_trees engine == xgboost

Hey all, I'm learning the ways of tidymodels to build my ML algorithms after using the underlying packages for years. I'm hoping the unified syntax of tidymodels will make it easier for me to share my work with my team. GPU support for XGBoost is crucial to my work as models take way too long to train without it. I read the boost_trees documentation found here: https://parsnip.tidymodels.org/reference/boost_tree.html but didn't see any mention of whether or not boost_trees will support gpu compute when I use set_enginge("xgboost"). Does anyone know if boost_trees supports GPU compute, and if so, what argument do I need to provide to enable it?

GPU accelaration with tidymodels

I am working in a Kaggle notebook and I was wondering if you can use GPU acceleration with any of the tidymodels as it can accelerate training times up to 100x compared to CPU. I know it is possible for the 'xgboost' package (link) but I can't get it to work using the tidymodels interface if I for instance try: xg_model <- boost_tree( # trees = 1000, # tree_depth = tune(), min_n = tune(), # loss_reduction = tune(), ## first three: model complexity # sample_size = tune(), mtry = tune(), ## randomness # learn_rate = tune(), ## step size ) %>% set_engine("xgboost", tree_method = 'gpu_hist') %>% set_mode("classifi…

When I try

library(tidymodels)
xg_model <-
  boost_tree(
    # trees = 1000, 
    # tree_depth = tune(), min_n = tune(), 
    # loss_reduction = tune(),                     ## first three: model complexity
    # sample_size = tune(), mtry = tune(),         ## randomness
    # learn_rate = tune(),                         ## step size
  ) %>%
  set_engine("xgboost", tree_method = 'gpu_hist') %>%
  set_mode("classification") %>% fit(Species ~.,data=iris)

I get

Error in xgb.iter.update(bst$handle, dtrain, iteration - 1, obj) :
[09:00:18] amalgamation/../src/metric/../common/common.h:156: XGBoost version not compiled with GPU support.
Timing stopped at: 0 0 0

which would imply to me that it would use gpu, if my xgboost was compiled with that ability.

Right

Do you happen to know if there is a list of methods within tidymodels that would use the GPU? It could be resampling methods, modelling, recipes, etc.

sorry, I have no idea about that.
probably another good place to ask might be the issues board on Issues · tidymodels/tidymodels (github.com)

You have to compile xgboost yourself if you want GPU support. CRAN doesn't build the package for that. See this thread.

tidymodels just calls the function so, I believe , that it should just work as long as the package itself can do it.

My understanding is the GPU will really shine when using deep learning models or XGBoost and other tree models (if they have GPU support). It's because you need thousands of processes that can run in parallel. I don't think GPU will provide any boost for data pre-processing or resampling.

Not it is easier to use XGBoost with GPU support in R.
