Problems with Jupyter widgets install

[Iztok Jeras]

I get the next error after running jupyter on an ARM board:

 404 GET /jupyter/nbextensions/widgets/notebook/js/extension.js

Most of the Python packages are installed from Ubuntu 16.04.2 packages,

while Jupyter itself is installed with:

pip3 install jupyter

So all the code is rather fresh.

Here is the actual install script:

https://github.com/RedPitaya/RedPitaya/blob/master/OS/debian/jupyter.sh

Here is what I get while searching for extension.js:

# find / -name extension.js
/usr/local/share/jupyter/nbextensions/jupyter-js-widgets/extension.js
/usr/local/lib/python3.5/dist-packages/widgetsnbextension/static/extension.js

There are more than one widget packages for Jupyter,

and I am not sure which one to use and how to install (and configure) it.

And I would prefer not to install them all.

If there are recommendations regarding which widget system to use, I would like to hear it.

My preference is usually a rather stable package which is still actively developed.

Just in case compatibility with other systems matters.

We will offer our users to use matplotlib,

but a lot of the graphs will use bokeh,

since it allows updating data without redrawing the graph,

and it does it at a rather high refresh rate (10+ fps).

It seems the next install steps provide the necessary widgets related packages:

pip install ipywidgets
jupyter nbextension enable --py widgetsnbextension

The question about preferred widgets for future use is still open.
