Javascript Error: window.PyViz.plot_index is undefined #22

timothymillar · 2018-11-09T01:22:40Z

This is may already be fixed with #20 but thought it was worth reporting.

As in title I'm getting Javascript Error: window.PyViz.plot_index is undefined when plotting with Holoviews in Jupyterlab. Plot is fine in classic view.

versions:

jupyter                   1.0.0                    py36_7

Thanks for the report, could you mention what context this happened in? Were you updating a dynamic plot? I can only see it reaching that branch of code if that's the case and I don't quite understand how you could get that far without something else breaking.

timothymillar · 2018-11-09T01:49:31Z

A simple test notebook:

I'm just trying to setup jupyterhub with lab at the moment so quite possible something else causing an issue.

I tried rolling back to v0.6.2 (seems to be most recent full release?) but had the same issue.

Thanks for the quick response!

philippjfr · 2018-11-09T16:52:13Z

Thanks, could you also report your holoviews version and if you have a minute see if the problem persists with a current dev version installed with: conda install -c pyviz/label/dev holoviews.

timothymillar · 2018-11-11T20:51:45Z

Sorry, should have had that in the initial report.

The version I was using:

holoviews                 1.10.4
bokeh                     0.12.16
matplotlib                2.2.2
ipykernel                 4.8.2
ipython                   6.4.0

I created a new env but got the same issue:

holoviews                 1.11.0a10
bokeh                     1.0.0
matplotlib                3.0.1
ipykernel                 5.1.0
ipython                   7.1.1

Just a note on my setup, I have a single environment for running jupyterhub/lab which is connecting to these other environments via kernelspecs.

I'm using Firefox but get similar errors in chrome:

and safari:

Its possible there was an issue with deploying the hub/lab environment so I'll try to re-deploy that

timothymillar · 2018-11-11T22:36:47Z

After redeploying I still have the same issue but I think it's likely an issue installing the node packages based on the warnings (I'm not familiar with node so unsure how problematic these are):

philippjfr · 2018-11-13T12:06:59Z

Thanks for investigating this further. That's really frustrating, looking at those errors I don't see anything that would indicate there being a problem building the extension. If you could do me one more favor, would you mind loading JupyterLab, running hv.extension('bokeh') and then going to the browser JS console and checking whether window.PyViz or window.HoloViews are defined at all?

timothymillar · 2018-11-13T20:38:58Z

No worries, thanks again for your help!

Looks like they are both defined (and window.HoloViews has plot_index):

>>window.Bokeh
Object { version: "1.0.0", embed: {…}, protocol: {…}, _testing: {…}, logger: {…}, set_log_level: set_log_level()
, settings: {…}, Models: Models()
, index: {}, documents: [], … }

>> window.HoloViews
Object { init_slider: init_slider()
, init_dropdown: init_dropdown(), comms: {}, comm_status: {}, index: {}, plot_index: {}, kernels: {}, receivers: {}, MPLSelectionWidget: MPLSelectionWidget(), MPLScrubberWidget: MPLScrubberWidget(), … }

>> window.PyViz
Object { kernels: {…}, init_slider: init_slider()
, init_dropdown: init_dropdown(), comm_manager: {} }
