Using IPython / Jupyter Notebooks Under Version Control
Version ControlIpythonJupyter NotebookVersion Control Problem Overview
What is a good strategy for keeping IPython notebooks under version control?
The notebook format is quite amenable for version control: if one wants to version control the notebook and the outputs then this works quite well. The annoyance comes when one wants only to version control the input, excluding the cell outputs (aka. "build products") which can be large binary blobs, especially for movies and plots. In particular, I am trying to find a good workflow that:
- allows me to choose between including or excluding output,
- prevents me from accidentally committing output if I do not want it,
- allows me to keep output in my local version,
- allows me to see when I have changes in the inputs using my version control system (i.e. if I only version control the inputs but my local file has outputs, then I would like to be able to see if the inputs have changed (requiring a commit). Using the version control status command will always register a difference since the local file has outputs.)
- allows me to update my working notebook (which contains the output) from an updated clean notebook. (update)
As mentioned, if I chose to include the outputs (which is desirable when using nbviewer for example), then everything is fine. The problem is when I do not want to version control the output. There are some tools and scripts for stripping the output of the notebook, but frequently I encounter the following issues:
- I accidentally commit a version with the the output, thereby polluting my repository.
- I clear output to use version control, but would really rather keep the output in my local copy (sometimes it takes a while to reproduce for example).
- Some of the scripts that strip output change the format slightly compared to the
Cell/All Output/Clear
menu option, thereby creating unwanted noise in the diffs. This is resolved by some of the answers. - When pulling changes to a clean version of the file, I need to find some way of incorporating those changes in my working notebook without having to rerun everything. (update)
I have considered several options that I shall discuss below, but have yet to find a good comprehensive solution. A full solution might require some changes to IPython, or may rely on some simple external scripts. I currently use mercurial, but would like a solution that also works with git: an ideal solution would be version-control agnostic.
This issue has been discussed many times, but there is no definitive or clear solution from the user's perspective. The answer to this question should provide the definitive strategy. It is fine if it requires a recent (even development) version of IPython or an easily installed extension.
Update: I have been playing with my modified notebook version which optionally saves a .clean
version with every save using [Gregory Crosswhite's suggestions][gregory crosswhite solution]. This satisfies most of my constraints but leaves the following unresolved:
- This is not yet a standard solution (requires a modification of the ipython source. Is there a way of achieving this behaviour with a simple extension? Needs some sort of on-save hook.
- A problem I have with the current workflow is pulling changes. These will come in to the
.clean
file, and then need to be integrated somehow into my working version. (Of course, I can always re-execute the notebook, but this can be a pain, especially if some of the results depend on long calculations, parallel computations, etc.) I do not have a good idea about how to resolve this yet. Perhaps a workflow involving an extension like ipycache might work, but that seems a little too complicated.
Notes
Removing (stripping) Output
- When the notebook is running, one can use the
Cell/All Output/Clear
menu option for removing the output. - There are some scripts for removing output, such as the script nbstripout.py which remove the output, but does not produce the same output as using the notebook interface. This was eventually included in the [ipython/nbconvert][ipythonnbconvert] repo, but this has been closed stating that the changes are now included in [ipython/ipython][ipythonipython],but the corresponding functionality seems not to have been included yet. (update) That being said, [Gregory Crosswhite's solution][gregory crosswhite solution] shows that this is pretty easy to do, even without invoking [ipython/nbconvert][ipythonnbconvert], so this approach is probably workable if it can be properly hooked in. (Attaching it to each version control system, however, does not seem like a good idea — this should somehow hook in to the notebook mechanism.)

Version Control Solutions
Solution 1 - Version Control
Here is my solution with git. It allows you to just add and commit (and diff) as usual: those operations will not alter your working tree, and at the same time (re)running a notebook will not alter your git history.
Although this can probably be adapted to other VCSs, I know it doesn't satisfy your requirements (at least the VSC agnosticity). Still, it is perfect for me, and although it's nothing particularly brilliant, and many people probably already use it, I didn't find clear instructions about how to implement it by googling around. So it may be useful to other people.
-
Save a file with this content somewhere (for the following, let us assume
~/bin/ipynb_output_filter.py
) -
Make it executable (
chmod +x ~/bin/ipynb_output_filter.py
) -
Create the file
~/.gitattributes
, with the following content*.ipynb filter=dropoutput_ipynb
-
Run the following commands:
git config --global core.attributesfile ~/.gitattributes git config --global filter.dropoutput_ipynb.clean ~/bin/ipynb_output_filter.py git config --global filter.dropoutput_ipynb.smudge cat
Done!
Limitations:
- it works only with git
- in git, if you are in branch
somebranch
and you dogit checkout otherbranch; git checkout somebranch
, you usually expect the working tree to be unchanged. Here instead you will have lost the output and cells numbering of notebooks whose source differs between the two branches. - more in general, the output is not versioned at all, as with Gregory's solution. In order to not just throw it away every time you do anything involving a checkout, the approach could be changed by storing it in separate files (but notice that at the time the above code is run, the commit id is not known!), and possibly versioning them (but notice this would require something more than a
git commit notebook_file.ipynb
, although it would at least keepgit diff notebook_file.ipynb
free from base64 garbage). - that said, incidentally if you do pull code (i.e. committed by someone else not using this approach) which contains some output, the output is checked out normally. Only the locally produced output is lost.
My solution reflects the fact that I personally don't like to keep generated stuff versioned - notice that doing merges involving the output is almost guaranteed to invalidate the output or your productivity or both.
EDIT:
-
if you do adopt the solution as I suggested it - that is, globally - you will have trouble in case for some git repo you want to version output. So if you want to disable the output filtering for a specific git repository, simply create inside it a file .git/info/attributes, with
**.ipynb filter=
as content. Clearly, in the same way it is possible to do the opposite: enable the filtering only for a specific repository.
-
the code is now maintained in its own [git repo][4]
-
if the instructions above result in ImportErrors, try adding "ipython" before the path of the script:
git config --global filter.dropoutput_ipynb.clean ipython ~/bin/ipynb_output_filter.py
EDIT: May 2016 (updated February 2017): there are several alternatives to my script - for completeness, here is a list of those I know: nbstripout (other [variants][5]), nbstrip, [jq][6].

Solution 2 - Version Control
We have a collaborative project where the product is Jupyter Notebooks, and we've use an approach for the last six months that is working great: we activate saving the .py
files automatically and track both .ipynb
files and the .py
files.
That way if someone wants to view/download the latest notebook they can do that via github or nbviewer, and if someone wants to see how the the notebook code has changed, they can just look at the changes to the .py
files.
For Jupyter
notebook servers, this can be accomplished by adding the lines
import os
from subprocess import check_call
def post_save(model, os_path, contents_manager):
"""post-save hook for converting notebooks to .py scripts"""
if model['type'] != 'notebook':
return # only do this for notebooks
d, fname = os.path.split(os_path)
check_call(['jupyter', 'nbconvert', '--to', 'script', fname], cwd=d)
c.FileContentsManager.post_save_hook = post_save
to the jupyter_notebook_config.py
file and restarting the notebook server.
If you aren't sure in which directory to find your jupyter_notebook_config.py
file, you can type jupyter --config-dir
, and if you don't find the file there, you can create it by typing jupyter notebook --generate-config
.
For Ipython 3
notebook servers, this can be accomplished by adding the lines
import os
from subprocess import check_call
def post_save(model, os_path, contents_manager):
"""post-save hook for converting notebooks to .py scripts"""
if model['type'] != 'notebook':
return # only do this for notebooks
d, fname = os.path.split(os_path)
check_call(['ipython', 'nbconvert', '--to', 'script', fname], cwd=d)
c.FileContentsManager.post_save_hook = post_save
to the ipython_notebook_config.py
file and restarting the notebook server. These lines are from a github issues answer @minrk provided and @dror includes them in his SO answer as well.
For Ipython 2
notebook servers, this can be accomplished by starting the server using:
ipython notebook --script
or by adding the line
c.FileNotebookManager.save_script = True
to the ipython_notebook_config.py
file and restarting the notebook server.
If you aren't sure in which directory to find your ipython_notebook_config.py
file, you can type ipython locate profile default
, and if you don't find the file there, you can create it by typing ipython profile create
.
Here's our project on github that is using this approach: and here's a github example of exploring recent changes to a notebook.
We've been very happy with this.

I have created nbstripout
, based on MinRKs gist, which supports both Git and Mercurial (thanks to mforbes). It is intended to be used either standalone on the command line or as a filter, which is easily (un)installed in the current repository via nbstripout install

Since there exist so many strategies and tools to handle version control for notebooks, I tried to create a flow diagram to pick a suitable strategy (created April 2019)
Solution 5 - Version Control
After a few years of removing outputs in notebooks, I have tried to come up with a better solution. I now use Jupytext, an extension for both Jupyter Notebook and Jupyter Lab that I have designed.
Jupytext can convert Jupyter notebooks to various text formats (Scripts, Markdown and R Markdown). And conversely. It also offers the option to pair a notebook to one of these formats, and to automatically synchronize the two representations of the notebook (an .ipynb
and a .md/.py/.R
file).
Let me explain how Jupytext answers the above questions:
> allows me to choose between including or excluding output,
The .md/.py/.R
file only contains the input cells. You should always track this file. Version the .ipynb
file only if you want to track the outputs.
> prevents me from accidentally committing output if I do not want it,
Add *.ipynb
to .gitignore
> allows me to keep output in my local version,
Outputs are preserved in the (local) .ipynb
file
> allows me to see when I have changes in the inputs using my version control system (i.e. if I only version control the inputs but my local file has outputs, then I would like to be able to see if the inputs have changed (requiring a commit). Using the version control status command will always register a difference since the local file has outputs.)
The diff on the .py/.R
or .md
file is what you are looking for
> allows me to update my working notebook (which contains the output) from an updated clean notebook. (update)
Pull the latest revision of the .py/.R
or .md
file and refresh your notebook in Jupyter (Ctrl+R). You will get the latest input cells from the text file, with matching outputs from the .ipynb
file. The kernel is not affected, which means that your local variables are preserved - you can continue you work where you left it.
What I love with Jupytext is that the notebook (under the form of a .py/.R
or .md
file) can be edited in your favorite IDE. With this approach, refactoring a notebook becomes easy. Once you're done you just need to refresh the notebook in Jupyter.
If you want to give it a try: install Jupytext with pip install jupytext
and restart your Jupyter Notebook or Lab editor. Open the notebook that you want to version control, and pair it to a Markdown file (or a Script) using the Jupytext Menu in Jupyter notebook (or the Jupytext commands in Jupyter Lab). Save your notebook, and you'll get the two files: the original .ipynb
, plus the promised text representation of the notebook, that is a perfect fit for version control!
For those who may be interested: Jupytext is also available on the command line.
Solution 6 - Version Control
The very popular 2016 answers above are inconsistent hacks compared with the better way to do this in 2019.
Several options exist, the best that answers the question is Jupytext.
Catch the Towards Data Science article on Jupytext
The way it works with version control is you put both the .py and .ipynb files in version control. Look at the .py if you want the input diff, look at the .ipynb if you want the latest rendered output.
Notable mentions: VS studio, nbconvert, nbdime, hydrogen
I think with a little more work, VS studio and/or hydrogen (or similar) will become the dominant players in the solution to this workflow.

> Update: Now you can edit Jupyter Notebook > files directly in Visual Studio Code. You can choose to edit the > notebook or the converted python file.
I finally found a productive and simple way to make Jupyter and Git play nicely together. I'm still in the first steps, but I already think it is a lot better than all other convoluted solutions.
Visual Studio Code is a cool and open source code editor from Microsoft. It has an excellent Python extension that now allows you to import a Jupyter Notebook as python code. Now you also can directly edit Jupyter Notebooks.
After you import your notebook to a python file, all the code and markdown will be together in a ordinary python file, with special markers in comments. You can see in the image below:
Your python file just has the contents of the notebook input cells. The output will be generated in a split window. You have pure code in the notebook, it doesn't change while you just execute it. No mingled output with your code. No strange JSON incomprehensible format to analyze your diffs.
Just pure python code where you can easily identify every single diff.
I don't even need to version my .ipynb
files anymore. I can put a *.ipynb
line in .gitignore
.
Need to generate a notebook to publish or share with someone? No problem, just click the export button in the interactive python window
If you are editing the notebook directly, there's now a icon Convert and save to a python script
.
Here a screenshot of a notebook inside Visual Studio Code:
I've been using it just for a day, but finally I can happily use Jupyter with Git.
P.S.: VSCode code completion is a lot better than Jupyter.

Just come across "jupytext" which looks like a perfect solution. It generates a .py file from the notebook and then keeps both in sync. You can version control, diff and merge inputs via the .py file without losing the outputs. When you open the notebook it uses the .py for input cells and the .ipynb for output. And if you want to include the output in git then you can just add the ipynb.

def post_save(model, os_path, contents_manager):
"""post-save hook for converting notebooks to .py scripts"""
if model['type'] != 'notebook':

Unfortunately, I do not know much about Mercurial, but I can give you a possible solution that works with Git, in the hopes that you might be able to translate my Git commands into their Mercurial equivalents.
For background, in Git the add
command stores the changes that have been made to a file into a staging area. Once you have done this, any subsequent changes to the file are ignored by Git unless you tell it to stage them as well. Hence, the following script, which, for each of the given files, strips out all of the outputs
and prompt_number sections
, stages the stripped file, and then restores the original:
NOTE: If running this gets you an error message like ImportError: No module named IPython.nbformat
, then use ipython
to run the script instead of python
.
from IPython.nbformat import current
import io
from os import remove, rename
from shutil import copyfile
from subprocess import Popen
from sys import argv
for filename in argv[1:]:
# Backup the current file
backup_filename = filename + ".backup"
copyfile(filename,backup_filename)
try:
# Read in the notebook
with io.open(filename,'r',encoding='utf-8') as f:
notebook = current.reads(f.read(),format="ipynb")
# Strip out all of the output and prompt_number sections
for worksheet in notebook["worksheets"]:
for cell in worksheet["cells"]:
cell.outputs = []
if "prompt_number" in cell:
del cell["prompt_number"]
# Write the stripped file
with io.open(filename, 'w', encoding='utf-8') as f:
current.write(notebook,f,format='ipynb')
# Run git add to stage the non-output changes
print("git add",filename)
Popen(["git","add",filename]).wait()
finally:
# Restore the original file; remove is needed in case
# we are running in windows.
remove(filename)
rename(backup_filename,filename)
Once the script has been run on the files whose changes you wanted to commit, just run git commit
.
Solution 13 - Version Control
Al thought it is simple, is solve the problems above...
Concept
I use a very pragmatic approach; which work well for several notebooks, at several sides. And it even enables me to 'transfer' notebooks around. It works both for Windows as Unix/MacOS.Basically, do not track the .ipnyb
-files, only the corresponding .py
-files.
By starting the notebook-server with the --script
option, that file is automatically created/saved when the notebook is saved.
Those .py
-files do contain all input; non-code is saved into comments, as are the cell-borders. Those file can be read/imported ( and dragged) into the notebook-server to (re)create a notebook. Only the output is gone; until it is re-run.
Personally I use mercurial to version-track the .py
files; and use the normal (command-line) commands to add, check-in (ect) for that. Most other (D)VCS will allow this to.
Its simple to track the history now; the .py
are small, textual and simple to diff. Once and a while, we need a clone (just branch; start a 2nd notebook-sever there), or a older version (check-it out and import into a notebook-server), etc.
Tips & tricks
- Add *.ipynb to '.hgignore', so Mercurial knows it can ignore those files
- Create a (bash) script to start the server (with the
--script
option) and do version-track it - Saving a notebook does save the
.py
-file, but does not check it in.- This is a drawback: One can forget that
- It's a feature also: It possible to save a notebook (and continue later) without clustering the repository-history.
Wishes
- It would be nice to have a buttons for check-in/add/etc in the notebook Dashboard
- A checkout to (by example)
file@date+rev.py
) should be helpful It would be to much work to add that; and maybe I will do so once. Until now, I just do that by hand.

I've built python package that solves this problem
https://github.com/brookisme/gitnb
It provides a CLI with a git-inspired syntax to track/update/diff notebooks inside your git repo.
Heres' an example
# add a notebook to be tracked
gitnb add SomeNotebook.ipynb
# check the changes before commiting
gitnb diff SomeNotebook.ipynb
# commit your changes (to your git repo)
gitnb commit -am "I fixed a bug"
Note that last step, where I'm using "gitnb commit" is committing to your git repo. Its essentially a wrapper for
# get the latest changes from your python notebooks
gitnb update
# commit your changes ** this time with the native git commit **
git commit -am "I fixed a bug"
There are several more methods, and can be configured so that it requires more or less user input at each stage, but thats the general idea.

It also has some git hooks that help a little https://nbdev.fast.ai/#Avoiding-and-handling-git-conflicts and the other commands like:
- nbdev_read_nbs

After digging around, I finally found this relatively simple pre-save hook on the Jupyter docs. It strips the cell output data. You have to paste it into the jupyter_notebook_config.py

"""scrub output before saving notebooks"""
# only run on notebooks
if model['type'] != 'notebook':

continue
cell['outputs'] = []
cell['execution_count'] = None
# Added by binaryfunt:

This is April-2020 and there are lots of strategies and tools for Jupyter notebook version control. Here's a quick overview of all the tools you can use,
-
nbdime - Nice for local diff'ing and merging of notebooks
-
nbstripout - A git filter to automatically remove notebook outputs before each commit
-
jupytext - Keeps a .py companion file sync'ed to each notebook. You only commit .py files
-
nbconvert - Convert notebooks to a python script or HTML (or both) and commit these alternate file types
-
ReviewNB - Shows notebook diff (along with output) for any commit or pull request on GitHub. One can also write comments on notebook cells to discuss changes (screenshot below).
Disclaimer: I built ReviewNB.
Solution 19 - Version Control
I did what Albert & Rich did - Don't version .ipynb files (as these can contain images, which gets messy). Instead, either always run ipython notebook --script
or put c.FileNotebookManager.save_script = True
in your config file, so that a (versionable) .py
file is always created when you save your notebook.
To regenerate notebooks (after checking out a repo or switching a branch) I put the script py_file_to_notebooks.py in the directory where I store my notebooks.
Now, after checking out a repo, just run python py_file_to_notebooks.py
to generate the ipynb files. After switching branch, you may have to run python py_file_to_notebooks.py -ov
to overwrite the existing ipynb files.
Just to be on the safe side, it's good to also add
*.ipynb
to your .gitignore
file.
Edit: I no longer do this because (A) you have to regenerate your notebooks from py files every time you checkout a branch and (B) there's other stuff like markdown in notebooks that you lose. I instead strip output from notebooks using a git filter. Discussion on how to do this is here.
Solution 20 - Version Control
Ok, so it looks like the current best solution, as per a discussion here, is to make a git filter to automatically strip output from ipynb files on commit.
Here's what I did to get it working (copied from that discussion):
I modified cfriedline's nbstripout file slightly to give an informative error when you can't import the latest IPython:
https://github.com/petered/plato/blob/fb2f4e252f50c79768920d0e47b870a8d799e92b/notebooks/config/strip_notebook_output
And added it to my repo, lets say in ./relative/path/to/strip_notebook_output
Also added the file .gitattributes file to the root of the repo, containing:
*.ipynb filter=stripoutput
And created a setup_git_filters.sh
containing
git config filter.stripoutput.clean "$(git rev-parse --show-toplevel)/relative/path/to/strip_notebook_output"
git config filter.stripoutput.smudge cat
git config filter.stripoutput.required true
And ran source setup_git_filters.sh
. The fancy $(git rev-parse...) thing is to find the local path of your repo on any (Unix) machine.

You can use this jupyter extension. It will enable you to directly upload your ipython notebooks to github.

Solution 22 - Version Control
How about the idea discussed in the post below, where the output of the notebook should be kept, with the argument that it might take a long time to generate it, and it is handy since GitHub can now render notebooks. There are auto-save hooks added for exporting .py file, used for diffs and .html for sharing with team members who do not use notebooks or git.
