I see the notebook opening in the Edge browser:Īlthough on Mac OS X, I installed spylon-kernel first and then discovered almond, here I do in the reverse because if you are not interested in Scala without Spark, you can install Almond and stop there. To access the notebook, open this file in a browser:įile:///home/coredump/.local/share/jupyter/runtime/nbserver-7065-open.html

If I run the notebook I get instructions on how to launch it in the browser: $ jupyter notebook

BREW INSTALL JUPYTER NOTEBOOK UPDATE

The following components were needed for Jupyter Notebook: $ sudo apt update I used the Debian environment left after the previous Scala Native installation so some prerequisites like JDK were already installed. Fortunately, WSL2 allows running Jupyter kernels inside Linux userspace but having a Web GUI using native Windows browsers via a local network. I thought it would be good to have a similar multilanguage environment on WSL2 and Debian for later experiments there.

BREW INSTALL JUPYTER NOTEBOOK MAC OS X

When installing it on Mac OS X for Matplotlib experimentation, I looked for Scala visualization alternatives and noticed Scala plugins for Jupyter.

Jupyter Notebook and Python are widely used in the cybersecurity domain.
