Fearless interactivity for Jupyter notebooks.
Project description
nbsafety
About
nbsafety
adds a layer of protection to computational notebooks by solving the
stale dependency problem, a problem which exists due to the fact that
notebooks segment execution into "cells" with implicit dependencies amongst
themselves. Here's an example in action:
nbsafety
accomplishes its magic using a combination of a runtime tracer (to
build the implicit dependency graph) and a static checker (to provide warnings
before running a cell), both of which are deeply aware of Python's data model.
In particular, nbsafety
requires minimal to no changes in user
behavior, opting to get out of the way unless absolutely necessary and letting
you use notebooks the way you prefer.
Install
To install, grab the package and install the Jupyter kernel spec as follows:
pip install nbsafety
python -m nbsafety.install
Running
Because nbsafety
is implemented as a custom Jupyter kernel, it works for
both Jupyter notebooks and JupyterLab.
To run an nbsafety
kernel, select "Python 3 (nbsafety)" from the list
of notebook types in Jupyter's "New" dropdown dialogue:
For JupyterLab, similarly select "Python 3 (nbsafety)" from the list of available kernels in the Launcher tab:
Uninstall
In addition to pip uninstall nbsafety
, it is also necessary
to deregister the kernel from Jupyter for a full uninstall:
jupyter kernelspec uninstall nbsafety
