reload Python module within Jupyter notebook (without autoreload)

Question

I have the following folder structure

project/
  src/
    __init__.py
    mymodule.py
  mynotebook.ipynb

within mynotebook I can import mymodule using standar formula from src.mymodule import *. The problem pops up when modifying mymodule and trying to reimport it without stopping the kernel. I am following this discussion but it is not working. (python ver: 3.3.5)

from imp import reload 
reload(src.mymodule) # also reload(mymodule)

the code above fails with message name 'src' is not defined (also name 'mymodule' is not defined). I can't use ipython's autoreload because I have no permissions to install it.

Thanks!

You need to import src too and then reload(src.mymodule).

from src import mymodule
import src
# Change in mymodule
reload(src.mymodule)

Quick note for python3: use importlib.reload

@JamesOwers BTW, do those magic commands work in Jupyter notebook? Such as %autoload 2?

This embellishes James Owers's comment from the Python3 documentation @ https://docs.python.org/3/library/importlib.html

This is my module import, when I edit the model I need to reload it.

import src.project.model as Mdl

This gives us the reload function

from importlib import reload

.. and when you want to reload your module in a cell

reload(Mdl)

What if I just load bunch of function by from MyFile import *? How can I reload all functions?
