Error in ablation analysis

[souzamarcelo]

I am trying to run the ablation analysis from terminal. I get the following error message:

Error in do.call(ablation, args = c(list(iraceResults = iraceResults,  : 
  objeto 'scenario' não encontrado
Calls: ablation_cmdline -> do.call

It seems that the scenario object was not found in the irace log file (it is in there, though).

I am using irace version 3.5. I also tried the repository version; no success. I attached the irace.Rdata I am using here.

Cheers!

Hi @souzamarcelo , could you tell me how you called ablation from the command-line? Using the version from github, I tried this:

ablation -l irace.Rdata 
#------------------------------------------------------------------------------

# called with: -l irace.Rdata
Error: == irace == Unknown scenario parameters: forbiddenFile, targetRunnerLauncherArgs
Execution halted

The error above is expected as those scenario options have been renamed.

I tried both commands given below.

First:

ablation -l irace.Rdata

Second:

ablation -l irace.Rdata -s scenario.txt

Could you try with the version in github? It should show as 3.5.1.9000.

[souzamarcelo]

Here is the error using the github version (same as yours).

ablation -l irace.Rdata -s scenario.txt 
#------------------------------------------------------------------------------

I give the scenario file here. I did not define a forbiddenFile or any target runner additional argument.

Here is the error using the github version (same as yours).
I give the scenario file here. I did not define a forbiddenFile or any target runner additional argument.

Some scenario options have been removed or will change in the next version of irace. Try this:

library(irace)
iraceResults <- read_logfile("irace.Rdata")
iraceResults$scenario$targetRunnerLauncher <- NULL
iraceResults$scenario$targetRunnerLauncherArgs <- NULL
iraceResults$scenario$forbiddenFile <- NULL
save(iraceResults, file="irace2.Rdata")
ablation_cmdline("-l irace2.Rdata")

Now it works, thank you!

I think it would be great to update the ablation function in the current version, to work according to the current structure of the iraceResults. In any case, I am closing this issue.
