mb706 / automlr Goto Github PK

Maybe when only one learner is used, preproc disregards permissible output types?

The error seems to be in buildWrapperSearchspace.R, where dtWrap contains qNot(asQuoted(cbiparam)), which evaluates to TRUE if there are no missings. Maybe the default value of automlr.convert.before.impute should be re-thought; otherwise, there should be one more requirement here.

learningrate.factor should have a $plus and $minus component, learningrate.limit a $min and $max component.

Trying to install this per the instructions in the README and it fails. Help troubleshooting?

Running RStudio Server on CentOS. I followed the instructions to run devtools::install_github("mb706/mlr", ref = "mb706_CPO") before starting.

Looks like it's breaking when it's trying to access mlrLearners.R, which I don't see in the R subdirectory. Here's my log:

Installation failed: Command failed (1)

As described in the installation section, the installation of automlr is currently only possible by using the adapted MLR version that contains a specific CPO extension. However, this version of MLR is not up-to-date and the pull request mentioned in the installation section is already merged into MLR. Therefore, I was trying to install automlr with the current MLR version(2.12.1). This fails with the following error message:

It suspect that the makeCPO method was removed again from MLR and moved to mlrCPO. Therefore, I installed mlrCPO and added it as a dependency to a local clone of the automlr repo. Unfortunately, the installations fails again, giving me the following error:

for (n in names(data)) {
data[[n]] = factor(data[[n]], levels = c("MISSING", levels(data[[n]])))
data[[n]][is.na(data[[n]])] = "MISSING"
}
data
})

It seems that the CPO calls used in master/R/CPO.R are outdated. It there any chance to get automlr running with the current MLR release or would this require a lot of work on automlr to get this up-to-date?
