error when loading mlr3verse:

[drag05]

I have this error message when loading mlr3verse:

require(mlr3verse)

Loading required package: mlr3verse
Loading required package: mlr3
Loading required package: mlr3filters
Loading required package: mlr3learners
Loading required package: mlr3pipelines
Loading required package: mlr3tuning
Error: package or namespace load failed for ‘mlr3tuning’ in namespaceExport(ns, exports):
 undefined exports: trm
Failed with error:  ‘package ‘mlr3tuning’ could not be loaded’

Since it had worked before, I re-installed mlr3verse and then mlr3tuning separately to no avail. Please advise

Thank you!

I'd say reinstalling mlr3tuning and then restarting the session should help.

If not, please provide a reprex.

@pat-s Hello, Thank you for replay! As I have mentioned above I have already re-installed mlr3tuning and mlr3verse. As advised, I am re-installing mlr3tuning again. Here is what happens:

I suspect some other package (like {mlr3}) is trying to load some new functions from {mlr3tuning} but fails because package versions do not align (trm is new sugar in v0.2.0 in {mlr3tuning}). Try updating all mlr3 related packages.

@pat-s: I was hoping the version match is insured by mlr3verse itself.

The list of my mlr3 packages:

Could it be that any of the packages in installation warning are the cause? I would load each package individually but mlr3tuning cannot be loaded yet:

> require(mlr3tuning)

Loading required package: mlr3tuning
Error: package or namespace load failed for ‘mlr3tuning’ in namespaceExport(ns, exports):

Please advise. Thank you!

Re-installing bbotk seems to have done the trick:

Restarting R session...

> require(mlr3verse)
Loading required package: mlr3verse
Loading required package: mlr3
Loading required package: mlr3filters
Loading required package: mlr3learners
Loading required package: mlr3pipelines
Loading required package: mlr3tuning
Loading required package: mlr3viz
Loading required package: paradox

Thank you!

[pat-s]

Thanks for the reply. Makes sense, {bbotk} is a utility package for {mlr3tuning} and should also be updated when {mlr3tuning} is updated.

Generally it is a good approach to always update all packages once a week or so.

@pat-s

It wasn't an update per se, just re-installation; before and after versions of bbotk were similar.

Thank you for your time!
