Slideshow editing with Jupyter Lab

It is still possible using nbconvert

Presenting Code Using Jupyter Notebook Slides

command you need to run:

jupyter nbconvert jupyter_notebook.ipynb --to slides --post serve

In Jupyter Lab you can alter the 'slide type' in the 'Cell Inspector' menu.

I have jupyter lab 1.1.4 installed on Ubuntu 18.04.3 LTS and am using a python 3 virtual env kernel and it works great. Just complete your notebook and then configure each cell using the "Notebook Tools" tab on the far left (as shown in screenshot). Then save and close the notebook and run below command to output the slides.

Open the terminal and navigate to the recently saved .ipynb and run

jupyter nbconvert Untitled2.ipynb --to slides

For slides or say

jupyter nbconvert Untitled2.ipynb --to pdf

For a pdf

Note: You might need to install the Tex package to perfrom pdf outputs. See the docs here or just run the below command to install it.

sudo apt-get install texlive-xetex texlive-fonts-recommended texlive-generic-recommended
