Much to my delight I saw there now is an AutoML Component for regression modeling, so I had a shot at it with some hERG SAR data from ChEMBL. However the component stalls quickly with the following warning being displayed:
WARN Capture Workflow End 4:0:0:1313:0:1561:0:1559:0:1554:0:1478 No corresponding ‘Capture Workflow Start’ node found
After digging deep into the AutoML Component I believe this is where the workflow stalls:
Not having used Workflow Capturing before, can anyone tell if these nodes are properly connected (I have not changed anything, this is as I downloaded the Component)? Seems to me there are tables missing that should be connected to the two ‘Reference Column Filter’ nodes.
I haven’t tested this extensively yet, but it seems likely this is a result of us adding dynamic ports to the Capture Workflow Start and Capture Workflow End nodes. It’s not obvious to me yet why the nodes in my screenshot are connected but yours aren’t.
I am using KNIME AP 4.5 also. Not sure what happened, but I reinstalled the AutoML component (drag&drop from the hub) and now it seems to run all the way through
