Install Python with Jupyter

The easiest way to install the Jupyter Notebook App is installing a scientific python distribution which also includes scientific python packages. The most common distribution is called Anaconda:

  • Download Anaconda Distribution (a few 100MB), Python 3, 64 bits.
  • Install it using the default settings for a single user.

Download Anaconda for Windows : Click here

Launching Jupyter Notebook App

The Jupyter Notebook App can be launched by clicking on the Jupyter Notebook icon installed by Anaconda in the start menu (Windows) or by typing in a terminal (cmd on Windows):

jupyter notebook

This will launch a new browser window (or a new tab) showing the Notebook Dashboard, a sort of control panel that allows (among other things) to select which notebook to open.

When started, the Jupyter Notebook App can access only files within its start-up folder (including any sub-folder). No configuration is necessary if you place your notebooks in your home folder or sub-folders. Otherwise, you need to choose a Jupyter Notebook App start-up folder which will contain all the notebooks.

Change Jupyter Notebook startup folder (Windows)

  • Copy the Jupyter Notebooklauncher from the menu to the desktop.
  • Right click on the new launcher and change the Target field, change %USERPROFILE%  to the full path of the folder which will contain all the notebooks.
  • Double-click on the Jupyter Notebook desktop launcher (icon shows [IPy]) to start the Jupyter Notebook App. The notebook interface will appear in a new browser window or tab. A secondary terminal window (used only for error logging and for shut down) will be also opened.

Change Jupyter Notebook startup folder (Mac OS)

To launch Jupyter Notebook App:

  • Click on spotlight, type terminalto open a terminal window.
  • Enter the startup folder by typing cd/some_folder_name.
  • Type jupyter notebook to launch the Jupyter Notebook App The notebook interface will appear in a new browser window or tab.

Shut down the Jupyter Notebook App

Closing the browser (or the tab) will not close the Jupyter Notebook App. To completely shut it down you need to close the associated terminal.

In more detail, the Jupyter Notebook App is a server that appears in your browser at a default address (http://localhost:8888). Closing the browser will not shut down the server. You can reopen the previous address and the Jupyter Notebook App will be re-displayed.

You can run many copies of the Jupyter Notebook App and they will show up at a similar address (only the number after “:”, which is the port, will increment for each new copy). Since with a single Jupyter Notebook App you can already open many notebooks, we do not recommend running multiple copies of Jupyter Notebook App.

Executing a notebook

Download the notebook you want to execute and put it in your notebook folder (or a sub-folder of it).

Then follow these steps:

  • Launch the Jupyter Notebook App (see previous section).
  • In the Notebook Dashboard navigate to find the notebook: clicking on its name will open it in a new browser tab.
  • Click on the menu Help -> User Interface Tour for an overview of the Jupyter Notebook App user interface.
  • You can run the notebook document step-by-step (one cell a time) by pressing shift + enter.
  • You can run the whole notebook in a single step by clicking on the menu Cell -> Run All.
  • To restart the kernel (i.e. the computational engine), click on the menu Kernel -> Restart. This can be useful to start over a computation from scratch (e.g. variables are deleted, open files are closed, etc…).
