How to update stop parameter from within the model?

Hi friends.
I’m probably missing something really basic from the documentation and examples, but reading:


and

I could not grasp how does one update the step/stop parameter? I.e. how do I link training_iteration ray expects to my model.

Furthermore, do I have any way of knowing if the scheduling/ optimization is “running”?
Meaning, when setting stop='foo' (I have no foo variable…) for tune.run(), I get no warnings and the task runs transparently to the fact it does not know what is the training step - which means it cannot really early stop or optimize for better parameters.

Thanks!
