Issue
Change some individual variable imputer to Model based (Random forest)
Remove the Impute widget. Create a new Impute widget and connect it to File again (without connecting it to any learner):
with the same file opened in File. The Impute widget restores the variables' state as model (Random forest) but there is no Random forest input.
The problem is that Impute stores actual constructed
Imputer
instances in its settings.Description of changes
Explicitly model what the widget does and not only its (by) products.
