autoupdate module in IPython / jupyter notebook

Question

I wrote my own module which as the following structure:

mymodule/
├── __init__.py
├── part1.py
├── part2.py
├── part3.py
└── part4.py

To test my module I am using IPython and/or jupyter notebook (formerly Ipython Notebook). As usual I do the module import like

import mymodule

Let's say I edit some code in part2.py and want to use the updated version of my module. First I thought just re-importing the module by import mymodule would do the job, but it does not. To completely reload the module I have to close IPython's shell or restart jupyter's kernel and start again by importing mymodule.

However, reffering to the docs, IPython provides an auto-update function called autoreload which provides different modes and could be activated as follows:

%load_ext autoreload
%autoreload 1
%aimport mymodule

Using both of my snippets, I am importing mymodule like that:

%load_ext autoreload
%autoreload 1
%aimport mymodule

import mymodule

# let's do something with the module here

However, even with activated autoreload 1 or autoreload 2 neither IPython nor jupyter are doing what I expect them to do and I still have to quit IPython's shell or restart jupyter's kernel in order to use the edited code of part2.py which is part of mymodule.

What am I doing wrong? It seems that I did not get the point about how this should work.

Answer 1

Change %autoreload 1 to %autoreload 2 like dashesy said, old version or bug.
