Write CSV only if dataset is not empty
Learner III am creating a couple of csv after some processing, ocassionally one or more of the datasets are empty (0 examples). Problem is they are still created as CSV that only shows the attributes and in that case, I rather skip the Write CSV operator.
I imagine I have to go with the branch operator, but I don't understand how to use it to check the numbers of example to use it as a condition.

In the branch options you can select minimum examples with the drop down
condition type -> min_examples
condition value -> 1
So in this case your output has to have at least 1 example, otherwise it's empty5
