Re: [jupyter] Jupyter doesn't see my Python package modifications

[Joe Quigley]

If you use it in a Jupyter Notebook or Lab, you can handle this by restarting the kernel. This can be done via "Kernel > Restart" or by pressing the 0 (zero) key twice.

The reason why this happens is because Python caches imported modules. Your changes aren't reflected in the module cache, so when you go to re-import it will simply pull from the cache again. Restarting the kernel will create a new Python process with an empty module cache- restarting the Jupyter server has the same effect.

(as an aside, you don't have to press the "synchronize" button in PyCharm. That is more for JetBrains internals- typically, you use it as a troubleshooting step when dealing with PyCharm bugs.)

Hello everyone,

I'm learning to handle Jupyter in a more advanced way and I have this doubt:

I created a package with Python scripts under the directory "my_packages", and developed its content with the PyCharm editor. I import this package from Jupyter notebook. So that all works well.

The problem is when I make changes to my package code. When I want to update the changes, I click on the PyCharm "Synchronize" button, but in order to make Jupyter see it I have to turn Jupyter off and on again.

As an addition, Jupyter runs under an Anaconda environment and I have exported in .bashrc the path of the package directory:

export PYTHONPATH="$HOME/root_package/":${PYTHONPATH}

export JUPYTER_PATH="$HOME/root_package/":${JUPYTER_PATH}

export PYTHONPATH

export JUPYTER_PATH

I've already tried everything I can imagine (adding channels to anaconda, etc.)

I can't turn Jupyter on and off every time I make a modification to my package. 

What can I do?

Thank you in advance
