Jupyter Notebook & Lab Server on Raspberry PiIntroProject Jupyter not only revolutionizes data-heavy research across domains - it also boosts personal productivity for problems on a much smaller scale. Due to openness it is an amazing platform for exploring concepts and learning new things. I started setting up a Jupyter Notebook Server on a Raspberry Pi following this blog post by Arun Durvasula. Convinced of the potential of the platform I followed the development. My personal exercise soon taught me a great deal about the underlying architcture. Given Jupyter's complexity, speed of growth and scale, it is remarkable that such a system runs fine on a Raspberry Pi. This repository isn't really anything genuine: I owe big thanks to many contributors in the Jupyter, Raspberry Pi, Linux, Python, Julia and greater Open Source communities for providing all the beautiful building blocks - small and large. What is new?
What do you need to follow along?
InstallationIMPORTANT NOTE on fresh installations
First boot with fresh SD card
sudo apt install -y git
sudo sed -i -e 's/CONF_SWAPSIZE=100/CONF_SWAPSIZE=2048/' /etc/dphys-swapfile
sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start
git clone https://github.com/kleinee/jns
cd ~/jns/scriptsTechnically you can now run You might not want all features on your system. Feel free to edit `inst_jns.sh' to suit your requirements. Install required Raspbian packages with aptsudo ./prep.shA couple of packages from the Raspbian repository are required during installation and later for a some Python packages to work properly. The script just fetches these packages and installs them. #!/bin/bash

jupyter lab buildStart and access your serverActivate the virtual environmentSince you used a virtual environment to install Python modules, you need to activate this environment before you can start your server: source /home/pi/.venv/jns/bin/activateThe prompt will change to indicate successfull activation preceding (jns) pi@zerow:~ $Before you proceedAfter installation completes, you will still need to activate the change made to You can be accomplish this by any of the following:
That's the reason for this warning during node installation: You can see this by running the following commands after your installation completes: pi@test-pi:~/jns $ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games
pi@test-pi:~/jns $ . ~/.bashrc
pi@test-pi:~/jns $ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/home/pi/n/bin
pi@test-pi:~/jns $ If you look at your $PATH environment variable and see /home/pi/n/bin you are ready to use node. Also note that if you uninstall node with Start the serverTo start your server just type Access the serverTo access your server form a webbrowser on a computer running on the same network as your Raspberry Pi, just open a browser and use the Pi's IP address / port 8888 as the url. xxx.xxx.xxx.xxx:8888Change `xxx.xxx.xxx.xxx' to the IP address of the Raspberry Pi.
