import-ipynb's Introduction

Motivation

Suppose you want to import the contents of A.ipynb into B.ipynb.

Installation

pip install import-ipynb

How to use

Place both ipynb files in the same directory. Then, in the B.ipynb:

import import_ipynb
import A

Congratulations! You can now run any functions defined in A.ipynb from B.ipynb!

How it works

The code within import_ipynb.py defines a "notebook loader" that allows you to 'import' other ipynb files into your current ipynb file. This entails:

  1. load the notebook document into memory
  2. create an empty Module
  3. execute every cell in the Module namespace

Note that since every cell in the A.ipynb is executed when you import the the file, A.ipynb should only contain classes and function definitions (otherwise you'll end up loading all variables and data into memory).

Credits

The code within imoprt_ipynb.py comes from http://jupyter-notebook.readthedocs.io/en/latest/examples/Notebook/Importing%20Notebooks.html.

Riley F. Edmunds (@rileyedmunds) wrote instructions on how to use it and Lev Maximov (@axil) packaged it.

NameError: name 'injest' is not defined

Doesn't work using Gunicorn on Heroku

I am using import-ipynb locally and it works perfectly fine, but I can't get it to work with Gunicorn on Heroku (Ubuntu 20.04).

Neat tool - dependency fix?

This is a very neat package! Would you consider adding IPhython and nbformat as requirements in the setup.py so that they get automatically set up in a fresh installation?
