ngnk_kernel's Introduction

A Jupyter kernel for ngn/k

NOTE: This is alpha quality at best.

This is a jupyter kernel for ngn/k, derived from the bash_kernel.

To use the kernel with docker, see the file README-Docker.md

Install

Ensure that you have a working build of ngn/k. This kernel expects that you have built the k-libc version. Set the environment variable NGNKDIR

export NGNKDIR="/your/path/to/k/dir"

so that the executable can be reached as /your/path/to/k/dir/k-libc.

Now run

`python install.py --sys-prefix`

and start the notebook server

jupyter notebook

For details of how this works, see the Jupyter docs on wrapper kernels, and pexpect's docs on the replwrap module.

Installation Help: Kernel not recognized outside of project directory

Hey Stefan

First of all, thank you! Your resources have been exceptionally valuable 🙂 ❤️

I am trying to install the ngnk_kernel to play around with k and follow your k book.

I have successfully compiled ngn/k, and ran the installation script for the kernel.

Everything works as expected if I launch Jupyter from the project directory.

If I instead launch Jupyter from another directory then I get the following error and the kernel doesn't work.

Any advice on how to set things up so I can use this kernel independent of where I start Jupyter?

Thank again for all that you do
