To perform this tutorial we need Ubuntu or its based Linux systems with a non-root sudo access user and Python environment. And before moving further, first perform the system update that will rebuild the APT package manager cache.

sudo apt update && sudo apt upgrade

2. Install Python3 & PIP3 for Jupyter

The latest version of Python is 3, available to install via the official repository of Ubuntu 20.04.  Because we need a Python environment to install and use Jupyter Notebook. Therefore, first, install it.

sudo apt install python3

Also, we need a PIP package manager to install Jupyter Notebook, hence get that as well.

sudo apt install python3-pip

3. Upgrade PIP and install virtualenv

Once the above-given commands are completed, both Python3 and PIP3 will be on your system. Now, let’s first upgrade our system’s default PIP version to the latest one.

sudo pip3 install virtualenv
Install Python Environment

4. Create a Python virtual environment for Jupyter

Instead of installing Jupyter globally, let’s create an isolated Python environment for it.  Therefore, here we are creating our project directory called – demo you can name the folder whatever you want.

mkdir demo

Create a new Virtual environment inside the folder.

cd demo

Let’s give it a name- notebookenv, of course, you can assign a name whatever you want.

virtualenv notebookenv

Now, activate and load the created python environment for your current shell.

source notebookenv/bin/activate

You will see that your bash shell has been switched to your created environment.
