I have two files:

MyModule.py
MyNotebook.ipynb

I am using Jupyter Notebook, latest, and Python, latest. I have two code cells in my Notebook.

**Cell #1**

```
import some stuff
Run some code
(Keep everything in the environment takes about five minutes to run this cell).

```

**Cell #2**

```
import MyModule
Execute code from MyModule

```

I would like to make code changes in MyModule.py and rerun **Cell #2** but without restarting the kernel (**Cell #1** did a fair amount of work which I don't want to rerun each time).
If I simply run the second cell, those changes made to MyModule.py do not propagate through. I did some digging, and I tried using importlib.reload. The actual code for **Cell #2** :

```
from Nash.IOEngineNash import *
import importlib
importlib.reload(Nash.IOEngineNash)

```

Unfortunately, this isn't quite working. How can I push those changes in MyModule.py (or Nash/IOEngineNash.py in actual fact) into my Notebook without restarting the kernel and running from scratch?
