1. Install ipython:
pip install ipython
2. Create a default profile:
ipython profile create
3. Edit profile at: ~/.ipython/profile_default/ipython_config.py and add (or uncomment) the following lines:
c.InteractiveShellApp.exec_lines = []
c.InteractiveShellApp.exec_lines.append('%load_ext autoreload')
c.InteractiveShellApp.exec_lines.append('%autoreload 2')
Alternatively you can run the following commands each time you run the ipython shell:
%load_ext autoreload %autoreload 2
