Project description


Fabulous Extension for Reproducible Notebooks

fern is an extension for the Jupyter Lab Notebook that tracks and documents your workflow in

Install fern with pip and install the jupyter extension:

To activate fern, add the following lines to the top of your notebook

%track on "your amie API key"

To capture figures you'll also need to run

%matplotlib inline

If you want to turn the tracker off at any time just run

%track off

%track on "your amie API key" 


Q: How does it work?

We determine the inputs and outputs for each cell by building an AST of your code. Each new cell execution creates a new leaf in amie, which is attached in the tree where the most recent change in the new leaf's inputs occured as an output to a prior cell.
