autoreload with ipython

Ref: https://ipython.readthedocs.io/en/stable/config/extensions/autoreload.html

Start autoreload with ipython to automatically reload imported modules. This makes working in ipython while changing source code easier as you don’t have to restart kernels every time or reload using importlib everytime there is a change in the source code.

%load_ext autoreload
%autoreload 2

This method has its caveats and should be used carefully.
