Q: Do workflow sets require bundling?
I have performed a tuning process on a workflow set containing four workflows, which has taken 3-4 hours to complete. Because of the long processing time, I would like to save the completed workflow set so that it can be reloaded into a future R session without having to run the tuning again.
I tried to bundle the workflow set and save it using saveRDS(workflow_set), however it would not work. Unfortunately I didn't save the error message, but I'm pretty sure it said that I had to select one combination of tuning parameters for each of the four workflows, then I was allowed to bundle and save them individually. This is not ideal as I would like to perform some analysis/create visualisations of the tuning process, and for this I need to have all combinations of tuning parameters and the corresponding metrics.
The question is do I need to bundle the complete workflow set, or is it sufficient to simply call saveRDS(workflow_set)?
