Update widget export to 7.0

[jasongrout]

In order to keep live widget support in the html export, we'll need to figure out a way to support both 6.x and 7.x widget formats. At the very minimum, the script tag at

nbconvert/nbconvert/templates/html/full.tpl

Line 14 in db30363

<script src="https://unpkg.com/jupyter-js-widgets@2.0.*/dist/embed.js"></script>

needs to be changed.

How does it need to be changed?

[jasongrout]

@mpacer - I'm working on nailing down exactly what it changes to right now.

Adding this as a soon-to-be released patch release since I don't want to wait on this to get 5.3 out the door if at all possible.

The embedding changes needed are noted at http://ipywidgets.readthedocs.io/en/stable/migration_guides.html?highlight=migrate#updating-embedded-widgets

As noted in jupyter/nbviewer#717, it would be great if we could examine the metadata and see which widgets version we needed to embed.

Also, this ties into a larger conversation about how we provide custom renderers (in some sort of pluggable system).

Considering this was now fixed for nbviewer, is the solution transferable to nbconvert?

It's probably the same or very similar.

(nbviewer fixed this in jupyter/nbviewer#738)

[vidartf]

A proposed fix based on jupyter/nbviewer#738 is available in #792.

If I understand correctly, when this is solved we will have interactive widgets in static HTML export, is that correct? Among the two linked PRs (#778 and #792) is there any preferred approach? Anything we can do to help moving this forward? Thanks!

I think I'm having the same issue: I can view my interactive widget using NBViewer (or when copying an pasing the embed widgets output) but the widget is not rendering when I've saved the notebook as an HTML (from the notebook menu or using nbconvert from the command line). I also raised the issue here on the widget-ts-cookiecutter repo.

We frequently use widget embedding in static HTML files to share notebook results privately with collaborators by emailing them HTML files (who do now want to run Jupyter notebooks).

I see that the issue was closed by @SylvainCorlay in pull request #792, but has the updated version of nbconvert been released yet? If not, should I use a pre-release version of nbconvert?

Update: I cloned and pip installed the nbconvert repo and I'm able to generate an HTML file (link) with a working embedded widget using nbconvert from the command line but not from Jupyter notebook. Is there a way that I can get Jupyter notebook to use the locally installed version of nbconvert or is there a plan to release a new version of nbconvert with this functionality?

I also raised a similar issue about embedding the widget in a static HTML using Jupyter Lab here.

Hi can you share how exactly you fixed this? thanks.
