I wrote this simple watermark IPython magic function to conveniently add date- and time-stamps to my IPython notebooks. Also, I often want to document various system information, e.g., for my Python benchmarks series.
The watermark line magic can be directly installed from my GitHub repository via
In [1]:
%install_ext https://raw.githubusercontent.com/rasbt/watermark/master/watermark.py
To load the date magic, execute the following line in your IPython notebook or current IPython shell
In [2]:
%load_ext watermark
In order to display the optional watermark arguments, type
In [3]:
%watermark?
%watermark [-a AUTHOR] [-d] [-n] [-t] [-z] [-u] [-c CUSTOM_TIME] [-v]
[-p PACKAGES] [-h] [-m] [-g]
