The Jupyter project, formerly the IPython project, provides a collection of tools for scientific computing using powerful interactive shells that combine code execution with the creation of a live computational document. These notebook files can contain arbitrary text, mathematical formulas, input code, results, graphics, videos and any other kind of media that a modern web browser is capable of displaying. Whether you're absolutely new to Python and want to learn it in a fun, interactive environment or do some serious parallel/technical computing, the Jupyter Notebook is a great choice.

Azure provides a service that you can use to quickly start using Jupyter . By using the Azure Notebook Service, you can easily gain access to Jupyter's web-accessible interface to scalable computational resources with all the power of Python and its many libraries. Since the installation is handled by the service, users can access these resources without the need for administration and configuration by the user.
If the notebook service does not work for your scenario please continue to read this article which will will show you how to deploy the Jupyter Notebook on Microsoft Azure, using Linux virtual machines (VMs).
Azure has two different deployment models for creating and working with resources: Resource Manager and classic. This article covers using the Resource Manager deployment model, which Microsoft recommends for most new deployments instead of the classic deployment model.
The first step is to create a virtual machine (VM) running on Azure. This VM is a complete operating system in the cloud and will be used to run the Jupyter Notebook. Azure is capable of running both Linux and Windows virtual machines, and we will cover the setup of Jupyter on both types of virtual machines.
Follow the instructions given here to create a virtual machine of the Ubuntu distribution. This tutorial uses Ubuntu Server 14.04 LTS. We'll assume the user name azureuser.
After the virtual machine deploys we need to open up a security rule on the network security group. From the Azure preview portal, go to Network Security Groups and open the tab for the Security Group corresponding to your VM. You need to add an Inbound Security rule with the following settings: TCP for the protocol, *** for the source (public) port and 9999 for the destination (private) port.
While in your Network Security Group, click on Network Interfaces and note the Public IP Address as it will be needed to connect to your VM in the next step.
To run the Jupyter Notebook on our VM, we must first install Jupyter and its dependencies. Connect to your linux vm using ssh and the username/password pair you chose when you created the vm. In this tutorial we will use PuTTY and connect from Windows.
Install Anaconda, a popular data science python distribution, using one of the links provided from Continuum Analytics. As of the writing of this document, the below links are the most up to date versions.
|Python 3.4||Python 2.7|
|64 bit||64 bit|
|32 bit||32 bit|
As an example, this is how you can install Anaconda on Ubuntu
# install anaconda cd ~ mkdir -p anaconda cd anaconda/ curl -O https://3230d63b5fc54e62148e-c95ac804525aac4b6dba79b00b39d1d3.ssl.cf1.rackcdn.com/Anaconda3-2.3.0-Linux-x86_64.sh sudo bash Anaconda3-2.3.0-Linux-x86_64.sh -b -f -p /anaconda3 # clean up home directory cd .. rm -rf anaconda/ # Update Jupyter to the latest install and generate its config file sudo /anaconda3/bin/conda install -f jupyter -y /anaconda3/bin/jupyter-notebook --generate-config
After installing we need to take a moment to setup the configuration files for Jupyter. If you experience troubles with configuring Jupyter it may be helpful to look at the Jupyter Documentation for Running a Notebook Server.
cd to the profile directory to create our SSL certificate and edit
the profiles configuration file.
On Linux use the following command.
Use the following command to create the SSL certificate(Linux and Windows).
openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mycert.pem -out mycert.pem
Note that since we are creating a self-signed SSL certificate, when connecting to the notebook your browser will give you a security warning. For long-term production use, you will want to use a properly signed certificate associated with your organization. Since certificate management is beyond the scope of this demo, we will stick to a self-signed certificate for now.
In addition to using a certificate, you must also provide a password to protect your notebook from unauthorized use. For security reasons Jupyter uses encrypted passwords in its configuration file, so you'll need to encrypt your password first. IPython provides a utility to do so; at a command prompt run the following command.
/anaconda3/bin/python -c "import IPython;print(IPython.lib.passwd())"
This will prompt you for a password and confirmation, and will then print the password. Note this for the following step.
Enter password: Verify password: sha1:b86e933199ad:a02e9592e59723da722.. (elided the rest for security)
Next, we will edit the profile's configuration file, which is the
jupyter_notebook_config.py file in the directory you are in. Note that this file may not exist -- just create it if that is the case. This
file has a number of fields and by default all are commented out. You can open
this file with any text editor of your liking, and you should ensure that it
has at least the following content. Be sure to replace the password with the sha1 from the previous step.
c = get_config() # You must give the path to the certificate file. c.NotebookApp.certfile = u'/home/azureuser/.jupyter/mycert.pem' # Create your own password as indicated above c.NotebookApp.password = u'sha1:b86e933199ad:a02e9592e5 etc... ' # Network and browser details. We use a fixed port (9999) so it matches # our Azure setup, where we've allowed :wqtraffic on that port c.NotebookApp.ip = '*' c.NotebookApp.port = 9999 c.NotebookApp.open_browser = False
At this point we are ready to start the Jupyter Notebook. To do this, navigate to the directory you want to store notebooks in and start the Jupyter Notebook server with the following command.
You should now be able to access your Jupyter Notebook at the address
When you first access your notebook, the login page asks for your password. And once you log in, you will see the "Jupyter Notebook Dashboard", which is the ontrol center for all notebook operations. From this page you can create new notebooks and open existing ones.
If you click the New button, you will see the following opening page.
The area marked with an
In : prompt is the input area, and here you can
type any valid Python code and it will execute when you hit
click on the "Play" icon (the right-pointing triangle in the toolbar).
The notebook itself should feel very natural to anyone who has used Python and a word processor, because it is in some ways a mix of both: you can execute blocks of Python code, but you can also keep notes and other text by changing the style of a cell from "Code" to "Markdown" using the drop-down menu in the toolbar.
Jupyter is much more than a word processor as it allows the mixing of computation and rich media (text, graphics, video and virtually anything a modern web browser can display). You can mix, text, code, videos and more!
And with the power of Python's many excellent libraries for scientific and technical computing, in the following screenshot, a simple calculation can be performed with the same ease as a complex network analysis, all in one environment.
This paradigm of mixing the power of the modern web with live computation offers many possibilities, and is ideally suited for the cloud; the Notebook can be used:
As a computational scratchpad to record exploratory work on a problem.
To share results with colleagues, either in 'live' computational form or in hardcopy formats (HTML, PDF).
To distribute and present live teaching materials that involve computation, so students can immediately experiment with the real code, modify it and re-execute it interactively.
To provide "executable papers" that present the results of research in a way that can be immediately reproduced, validated and extended by others.
As a platform for collaborative computing: multiple users can log in to the same notebook server to share a live computational session.
If you go to the IPython source code repository, you will find an entire
directory with notebook examples which you can download and then experiment with on your own Azure Jupyter VM. Simply download the
.ipynb files from the site and upload them onto the dashboard of your notebook Azure VM (or download them directly into the VM).
The Jupyter Notebook provides a powerful interface for accessing interactively the power of the Python ecosystem on Azure. It covers a wide range of usage cases including simple exploration and learning Python, data analysis and visualization, simulation and parallel computing. The resulting Notebook documents contain a complete record of the computations that are performed and can be shared with other Jupyter users. The Jupyter Notebook can be used as a local application, but it is ideally suited for cloud deployments on Azure
The core features of Jupyter are also available inside Visual Studio via the Python Tools for Visual Studio (PTVS). PTVS is a free and open-source plug-in from Microsoft that turns Visual Studio into an advanced Python development environment that includes an advanced editor with IntelliSense, debugging, profiling and parallel computing integration.
