New message pops up when using Inference

[kordjamshidi]

I am running the EntityRelationApp$ and I see for all instances this warning is shown,

23:21:10 ERROR EntityRelationConstrainedClassifiers$LocConstrainedClassifier$:55 - Warning: Failed to find head

this was not the case before, does anyone made a change for logging? Does it mean the inference is not performed correctly?

As far as I know, this class hasn't been changed functionality-wise since May. Not sure abt the logger; you can check the history. What other strange behavior do you see? If the only issue is logger msgs, we can change its logging level.

There was one change in behavior made to ConstrainedClassifier. (I can find the specific commit).

When calling the .test() method on a ConstrainedClassifier, the test would run only on node instances that were accessed by the pathToHead constraint and not all testingIntances for the node. This was fixed so that the .test() method actually runs on all node.getAllTestingInstances. For node items that satisfy the constraint (via pathToHead, we build the InferenceCondition to get the result else we directly use the onClassifier.discreteValue.

You get the warnings here for those item that do not participate in the constraint represented by pathToHead.

Ok, thanks, this was useful. I am going to re-check.
