Have you always wished Jupyter notebooks were plain text documents? Wished you could edit them in your favorite IDE? And get clear and meaningful diffs when doing version control? Then... Jupytext may well be the tool you're looking for!
Jupytext is a plugin for Jupyter that can save Jupyter notebooks as either
Common use cases for Jupytext are:
You can install Jupytext with
pip install jupytext
conda install jupytext -c conda-forge.
Please note that Jupytext includes an extension for Jupyter Lab. In the latest version of Jupytext, this extension is compatible with Jupyter Lab >= 3.0 only. If you use Jupyter Lab 2.x, please either stay with Jupytext 1.8.2, or install, on top of the latest pip or conda version of Jupytext, a version of the extension that is compatible with Jupyter Lab 2.x:
jupyter labextension install [email protected] # For Jupyter Lab 2.x
Then, restart your Jupyter server (for more installation details, see the install section in the documentation).
When Jupytext is installed,
.md files have a notebook icon. And you can really open and run these files as notebooks
The most convenient way to use Jupytext is probably through paired notebooks.
To pair a given
.ipynb or text notebook to an additional notebook format, use either
jupytextat the command line
jupytext --set-formats ipynb,py:percent notebook.ipynb
see the documentation.
with e.g. the following content:
formats = "ipynb,py:percent"
see the documentation.
When you save a paired notebook in Jupyter, both the
.ipynb file and the text version are updated on disk.
When a paired notebook is opened or reloaded in Jupyter, the input cells are loaded from the text file, and combined with the output cells from the
You can edit the text representation of the notebook in your favorite editor, and get the changes back in Jupyter by simply reloading the notebook (Ctrl+R in Jupyter Notebook, "reload notebook" in Jupyter Lab). And the changes are propagated to the
.ipynb file when you save the notebook.
Alternatively, you can synchronise the two representations by running
jupytext --sync notebook.ipynb at the command line.
Jupytext implements many text formats for Jupyter Notebooks. If your notebook is mostly made of code, you will probably prefer to save it as a script:
# %%), supported by many IDE (Spyder, Hydrogen, VS Code, PyCharm and PTVS)
If your notebook contains more text than code, if you are writing a documentation or a book, you probably want to save your notebook as a Markdown document
.mdfile (without its outputs) on GitHub
