Task cbind breaks when task's backend has primary_key different to `..row_id`

When a `data.frame` is passed to `Task$cbind` `as_data_backend.data.frame` is called which automtically sets the primary key to `..row_id`

Task cbind breaks when task's backend has primary_key different to `..row_id`

Save only selected edges in graph learner

So currently it is not yet possible to solve your issue with callbacks and I am waiting for feedback whether we want to enable this here. We already have the...

resample$score(predict_sets = 'test') gives same output as resample$score(predict_sets = 'train'). Also, is there any functionality where results from both train and test can be accessed?

[Suggestion] Serialization property for learners

There is also this related package: https://github.com/HenrikBengtsson/marshal

[Suggestion] Serialization property for learners

this is implemented

Add tests for backward compatibility

I think we should write an FAQ entry how to circumvent these issues in case they appear. Maybe we could include a link to this FAQ entry in warning /...
