| This script is used to remove / reset outputs, execution numbers and metadata from .ipynb files for better version control. | |
| I created my own script to do this as I could not find any solution that performs all 3 operations properly. | |
| Usage: | |
| Put this script in the same directory as the jupyter notebook (.ipynb) files and run it. | |
| Note: | |
| Inspired by the jq method here: http://timstaley.co.uk/posts/making-git-and-jupyter-notebooks-play-nice/ | |
| Also this gist: https://gist.github.com/pbugnion/ea2797393033b54674af | |
