A brief history
• Spun off from ipython in
2014 by Fernando Pérez
• Jupyter core languages
• Julia
• Python
• R
• But now rather
agnostic (.net
anyone?)

9.
Notebooks TNG
• Released in 2018
• Same building blocks
• Cool new interface!

I want more!

12.
First Some setup
• Follow along: https://gitlab.com/denner1/cialug-august-2020-jupyter-lab
• Initial setup on Ubuntu Fossa (20.04) Docker image
• docker run -p 8080:8080 ubuntu:20.04
• Or easy button to skip ahead
docker run --rm -it –p 8080:8080 registry.gitlab.com/denner1/cialug-august-
2020-jupyter-lab:latest
• Please note: this image is not optimized for size or security
and is not production ready!

13.
Setup cont.
• First setup virtualenv and some prereqs
• apt-get install git r-base r-cran-devtools nodejs wget python3-pip build-essential libssl-
dev libffi-dev python-dev python3-venv
• source venv/bin/activate
• Verify which env we are in with ‘which pip’ (also note hint in the prompt)

14.
Why virtualenv
• Not really needed for docker
• Think of it as python in a bottle
• Other options are conda or
just yell YOLO (or docker in
our case)

15.
Setup cont.
• pip install jupyterlab ipywidgets
• jupyter lab –ip=0.0.0.0 –port=8080 –allow root
• Install R apt-get install r-base r-cran-devtools
• In R:
• devtools::install_github("IRkernel/IRkernel")
• IRkernel::installspec()
• GnuPlot
• apt install -y gnuplot
• pip install gnuplot_kernel
• python -m gnuplot_kernel install --user

16.
Useful tips
• ! Will run in the shell eg.
• !pip install packagename
• Tab completion is your friend
• help()
• quickref
• Lots of Kernels out there:
