jupyter notebook vs jupyterlabs

[Reimundo Heluani]

Dear all, I apologize that his may be out of place, but I started preparing
the sage days talk on jupyter and I find myself on a completely new
terri(fying)tory. I have a bunch of questions and I'd appreciate if you can
point me in the right direction to read.

1. I remember in this list there were a few calls to help on the migration
from jupyter notebook to jupyterlab, but I can't seem to surf those
e-mails. Has this effectively happened? This is probably the only
meaningful question, I want to rule out whether I am trying to write the
slides in the wrong environment first.

2. I am running on arch, and I have installed both jupyter notebook and
jupyterlab. When running sage with `sage -n jupyter --ip=127.0.0.1` there's
a trace with `ModuleNotFoundError: No module named 'jupyterlab'` and right
after the notebook runs fine, but with jupyter notebook, not jupyter lab

3. If I run jupyterlab with `jupyter lab` it does not recognize the sage
kernel (I run sage out of my local git repo). I do not know how to make it
visible to the system jupyterlab.

4. I don't particularly care for one or the other, I would just want to
construct a readable slideshow that more or less resembles a normal beamer
slideshow. Mathjax seems to be missing some Tex Fonts as I get

```
404 GET /nbextensions/mathjax/fonts/HTML-CSS/TeX/otf/MathJax_Script-Regular.otf (127.0.0.1) 62.44ms referer=http://127.0.0.1:8888/notebooks/Talk.ipynb
```
Should I install some extension to get these fonts.

5. The same with theorem-like definitions. I installed the extension
latex_envs following instructions in

https://jupyter-contrib-nbextensions.readthedocs.io/en/latest/nbextensions/latex_envs/README.html

But I can't get it to render a definition properly. I suspect this may be a
mixing of using a distro package manager for jupyter vs pip install for the
extension itself. What's the right way of checking which extensions are
running?

6. Finally, I find the workflow horrible: I make the notebook a slideshow,
then mark cells as slides, mode markdown, then type some math in them. If I
hit <Shit>-<Enter> to render them they render one way, then if I want to
run the slides with

`jupyter nbconvert Talk.ipynb --to slides --post serve`

They render in a different way. In particular headings and plain html code
like <p>text</p>

Is this the right workflow to prepare slides?

Thanks

R.

I just realized that running on the Python kernel the definition environment
renders correctly, so I guess this extension does not work with the sage
kernel.

Sage has not (yet) switched to jupyterlab, although there were various
ways to use jupyterlab with Sage posted here by Samuel, iirc.

Ahh thanks, in the third message in that discussion there were all the answers
I needed it seems.
