Issue with dash server occupying port when kernel is stopped

[jcarreira]

If I start a grid search run with UI on and kill the experiment mid way, it seems I can't rerun it without restarting jupyter.

The reason seems to be that the dash server is still bound on the port. What is the solution for this?

For now you can restart the jupyter kernel.

I will (in the Tuesday update) add a feature to ensure that port gets unbounded.
