Jupyter Notebook offers a command shell for interactive computing as a web application so that you can share and communicate with code. The tool can be used with several languages, including Python, Julia, R, Haskell, and Ruby. It is often used for working with data, statistical modeling, and machine learning.
This tutorial will walk you through setting up Jupyter Notebook to run from a Debian 10 server, as well as teach you how to connect to and use the Notebook. Jupyter Notebooks (or just “Notebooks”) are documents produced by the Jupyter Notebook app which contain both computer code and rich text elements (paragraph, equations, figures, links, etc.) which aid in presenting and sharing reproducible research.
By the end of this guide, you will be able to run Python 3 code using Jupyter Notebook running on a remote Debian 10 server.
In order to complete this guide, you should have a fresh Debian 10 server instance with a basic firewall and a non-root user with sudo privileges configured. You can learn how to set this up by running through our Initial Server Setup with Debian 10 guide.
To begin the process, we’ll download and install all of the items we need from the Debian repositories. We will use the Python package manager pip
to install additional components a bit later.
We first need to update the local apt
package index and then download and install the packages:
- sudo apt update
Next, install pip
and the Python header files, which are used by some of Jupyter’s dependencies:
- sudo apt install python3-pip python3-dev
Debian 10 (“Buster”) comes preinstalled with Python 3.7.
We can now move on to setting up a Python virtual environment into which we’ll install Jupyter.
Now that we have Python 3, its header files, and pip
ready to go, we can create a Python virtual environment for easier management. We will install Jupyter into this virtual environment.
To do this, we first need access to the virtualenv
command. We can install this with pip
.
Upgrade pip
and install the package by typing:
- sudo -H pip3 install --upgrade pip
- sudo -H pip3 install virtualenv
With virtualenv
installed, we can start forming our environment. Create and move into a directory where we can keep our project files:
- mkdir ~/myprojectdir
- cd ~/myprojectdir
Within the project directory, create a Python virtual environment by typing:
- virtualenv myprojectenv
This will create a directory called myprojectenv
within your myprojectdir
directory. Inside, it will install a local version of Python and a local version of pip
. We can use this to install and configure an isolated Python environment for Jupyter.
Before we install Jupyter, we need to activate the virtual environment. You can do that by typing:
- source myprojectenv/bin/activate
Your prompt should change to indicate that you are now operating within a Python virtual environment. It will look something like this: (myprojectenv)user@host:~/myprojectdir$
.
You’re now ready to install Jupyter into this virtual environment.
With your virtual environment active, install Jupyter with the local instance of pip
:
Note: When the virtual environment is activated (when your prompt has (myprojectenv)
preceding it), use pip
instead of pip3
, even if you are using Python 3. The virtual environment’s copy of the tool is always named pip
, regardless of the Python version.
- pip install jupyter
At this point, you’ve successfully installed all the software needed to run Jupyter. We can now start the Notebook server.
You now have everything you need to run Jupyter Notebook! To run it, execute the following command:
- jupyter notebook
A log of the activities of the Jupyter Notebook will be printed to the terminal. When you run Jupyter Notebook, it runs on a specific port number. The first Notebook you run will usually use port 8888
. To check the specific port number Jupyter Notebook is running on, refer to the output of the command used to start it:
Output[I 21:23:21.198 NotebookApp] Writing notebook server cookie secret to /run/user/1001/jupyter/notebook_cookie_secret
[I 21:23:21.361 NotebookApp] Serving notebooks from local directory: /home/sammy/myprojectdir
[I 21:23:21.361 NotebookApp] The Jupyter Notebook is running at:
[I 21:23:21.361 NotebookApp] http://localhost:8888/?token=1fefa6ab49a498a3f37c959404f7baf16b9a2eda3eaa6d72
[I 21:23:21.361 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[W 21:23:21.361 NotebookApp] No web browser found: could not locate runnable browser.
[C 21:23:21.361 NotebookApp]
Copy/paste this URL into your browser when you connect for the first time,
to login with a token:
http://localhost:8888/?token=1fefa6ab49a498a3f37c959404f7baf16b9a2eda3eaa6d72
If you are running Jupyter Notebook on a local Debian computer (not on a Droplet), you can simply navigate to the displayed URL to connect to Jupyter Notebook. If you are running Jupyter Notebook on a Droplet, you will need to connect to the server using SSH tunneling as outlined in the next section.
At this point, you can keep the SSH connection open and keep Jupyter Notebook running or can exit the app and re-run it once you set up SSH tunneling. Let’s keep it simple and stop the Jupyter Notebook process. We will run it again once we have SSH tunneling working. To stop the Jupyter Notebook process, press CTRL+C
, type Y
, and hit ENTER
to confirm. The following will be displayed:
Output[C 21:28:28.512 NotebookApp] Shutdown confirmed
[I 21:28:28.512 NotebookApp] Shutting down 0 kernels
We’ll now set up an SSH tunnel so that we can access the Notebook.
In this section we will learn how to connect to the Jupyter Notebook web interface using SSH tunneling. Since Jupyter Notebook will run on a specific port on the server (such as :8888
, :8889
etc.), SSH tunneling enables you to connect to the server’s port securely.
The next two subsections describe how to create an SSH tunnel from 1) a Mac or Linux and 2) Windows. Please refer to the subsection for your local computer.
If you are using a Mac or Linux, the steps for creating an SSH tunnel are similar to using SSH to log in to your remote server, except that there are additional parameters in the ssh
command. This subsection will outline the additional parameters needed in the ssh
command to tunnel successfully.
SSH tunneling can be done by running the following SSH command in a new local terminal window:
- ssh -L 8888:localhost:8888 your_server_username@your_server_ip
The ssh
command opens an SSH connection, but -L
specifies that the given port on the local (client) host is to be forwarded to the given host and port on the remote side (server). This means that whatever is running on the second port number (e.g. 8888
) on the server will appear on the first port number (e.g. 8888
) on your local computer.
Optionally change port 8888
to one of your choosing to avoid using a port already in use by another process.
server_username
is your username (e.g. sammy) on the server which you created and your_server_ip
is the IP address of your server.
For example, for the username sammy
and the server address 203.0.113.0
, the command would be:
- ssh -L 8888:localhost:8888 sammy@203.0.113.0
If no error shows up after running the ssh -L
command, you can move into your programming environment and run Jupyter Notebook:
- jupyter notebook
You’ll receive output with a URL. From a web browser on your local machine, open the Jupyter Notebook web interface with the URL that starts with http://localhost:8888
. Ensure that the token number is included, or enter the token number string when prompted at http://localhost:8888
.
If you are using Windows, you can create an SSH tunnel using Putty.
First, enter the server URL or IP address as the hostname as shown:
Next, click SSH on the bottom of the left pane to expand the menu, and then click Tunnels. Enter the local port number to use to access Jupyter on your local machine. Choose 8000
or greater to avoid ports used by other services, and set the destination as localhost:8888
where :8888
is the number of the port that Jupyter Notebook is running on.
Now click the Add button, and the ports should appear in the Forwarded ports list:
Finally, click the Open button to connect to the server via SSH and tunnel the desired ports. Navigate to http://localhost:8000
(or whatever port you chose) in a web browser to connect to Jupyter Notebook running on the server. Ensure that the token number is included, or enter the token number string when prompted at http://localhost:8000
.
This section goes over the basics of using Jupyter Notebook. If you don’t currently have Jupyter Notebook running, start it with the jupyter notebook
command.
You should now be connected to it using a web browser. Jupyter Notebook is a very powerful tool with many features. This section will outline a few of the basic features to get you started using the Notebook. Jupyter Notebook will show all of the files and folders in the directory it is run from, so when you’re working on a project make sure to start it from the project directory.
To create a new Notebook file, select New > Python 3 from the top right pull-down menu:
This will open a Notebook. We can now run Python code in the cell or change the cell to markdown. For example, change the first cell to accept Markdown by clicking Cell > Cell Type > Markdown from the top navigation bar. We can now write notes using Markdown and even include equations written in LaTeX by putting them between the $$
symbols. For example, type the following into the cell after changing it to markdown:
# First Equation
Let us now implement the following equation:
$$ y = x^2$$
where $x = 2$
To turn the markdown into rich text, press CTRL+ENTER
, and the following should be the results:
You can use the markdown cells to make notes and document your code. Let’s implement that equation and print the result. Click on the top cell, then press ALT+ENTER
to add a cell below it. Enter the following code in the new cell.
x = 2
y = x**2
print(y)
To run the code, press CTRL+ENTER
. You’ll receive the following results:
You now have the ability to import modules and use the Notebook as you would with any other Python development environment!
At this point, you should be able to write reproducible Python code and notes in Markdown using Jupyter Notebook. To get a quick tour of Jupyter Notebook from within the interface, select Help > User Interface Tour from the top navigation menu to learn more.
From here, you can begin a data analysis and visualization project by reading Data Analysis and Visualization with pandas and Jupyter Notebook in Python 3.
