Is there a way to run all Jupyter Notebooks inside a directory?

Introduction

I have a lot of Jupyter Notebooks inside a directory and I want to run them all to see them output.

What I actually do

I have to open them each one, click on “Restart kernel and re-run the whole notebook?”, wait a few minutes and then go for the next one.

What I wish to do

Find a way to just “press a button” (it can be a script, command, or everything), go away for a walk, and come back reading what’s the output.

Thanks in advance!

Answer

You can achieve this with nbconvert or papermill. See also this answer.

This is an example in papermill:

Installation with Anaconda:

conda install -c conda-forge papermill

Create a new notebook that runs all the notebooks in a specific directory:

import papermill as pm
from pathlib import Path

for nb in Path('./run_all').glob('*.ipynb'):
    pm.execute_notebook(
        input_path=nb,
        output_path=nb  # Path to save executed notebook
    )
