Group Loop + Parameter Optimization Loop + X-Partitioner (cross validation) Error

[rrodriguez]

Hello,

Is it possible to have Group Loop + Parameter Optimization Loop + X-Partitioner (cross validation) altogether?

I get “Can´t merge FlowVariable Stacks” error

I am able to make it work with “Parameter Optimization Loop + X-Partitioner” but not with Group Loop.

Anyone could help me, please?

THX

Hi @rrodriguez

Try wrapping the Parameter Loop Start to End into a Component .

Alternatively, you can also draw flow variable connections from the Group Loop Start to the Parameter Optimization Loop Start and the Parameter Optimization Loop End to the Loop End.

Solved!!! creating a component as you said

Thx very much

Hi I`ve been hours with this problem if anyone could help me, don’t know how to merge well the loops… This works but the problem I don’t know how to pass the prediction data to the joiner,
