Budget Allocator 1 and 2 #892

Closed DongHarry-Kang closed 8 months ago

DongHarry-Kang commented 9 months ago

Hi I am trying to do budget allocation, but I have repeatedly encounter issues; I have used the below methodologies to fix. I would like to report here in case other people also encounter the same error

  1. Buddget Allocator 1: when I used default code,

AllocatorCollect1 <- robyn_allocator( InputCollect = InputCollect, OutputCollect = OutputCollect, select_model = select_model, date_range = NULL, # Default last month as initial period total_budget = NULL, # When NULL, default is total spend in date_range channel_constr_low = 0.7, channel_constr_up = c(1.2, 1.5, 1.5, 1.5, 1.5), channel_constr_multiplier = 3, scenario = "max_response", export = create_files )

The system gave me the below error:

Running budget allocator for model ID 3_175_3 ... check_allocator_constrains(channel_constr_low, channel_constr_up) でエラー: Inputs 'channel_constr_up' and 'channel_constr_low' must have the same length or length 1

Therefore, I changed code of channel channel_constr_up = c(1.2, 1.5, 1.5, 1.5, 1.5) -> 1.3

And then I was able to get the result! :)

Strange, just tested and can't reproduce this error. Please reopen if it happens again
