Interactive Dashboard example shows no widgets with Jupyter Lab

[aavanian]

The example at interactive dashboards doesn't fully work in jupyter lab. The plot shows up but not the widgets.

I'm sure everything is ok with bokeh as I run multiple pure bokeh server app in the same jupyter lab environment.

bokeh-0.12.15.min.js:1 Jupyter notebooks comms not available. push_notebook() will not function. If running JupyterLab ensure the latest jupyterlab_bokeh extension is installed. In an exported notebook this warning is expected.

This is probably because the comms for parambokeh need updating for compatibility with Jupyterlab. I hope to update parambokeh soon so it will work.

This is being addressed in ioam/parambokeh#51

[philippjfr]

This has been fixed we are now just waiting on a new parambokeh release.
