Python is a popular programming language that is used extensively for data analysis, machine learning, and artificial intelligence. Ubuntu Linux is a popular operating system used by many developers, and it comes with Python pre-installed. However, there may be times when you need to install a Python library to extend the functionality of Python. In this article, we will discuss how to install Python libraries in Ubuntu Linux.
Before we begin, it’s important to note that there are two primary ways to install Python libraries in Ubuntu Linux: using pip, the Python package manager, or using apt-get, the Ubuntu package manager. We will discuss both methods below.
Method 1: Using pip
Pip is the default package manager for Python, and it allows you to easily install and manage Python libraries. To install a Python library using pip, follow these steps:
Step 1: Open the Terminal
To open the Terminal in Ubuntu, press the Ctrl + Alt + T keys on your keyboard.
Step 2: Install pip
If you don’t have pip installed, you can install it using the following command:
sudo apt install python3-pip
Step 3: Install the Python library
To install a Python library using pip, you can use the following command:
pip install <library-name>
For example, to install the numpy library, you would run the following command:
pip install numpy
Method 2: Using apt-get
Ubuntu Linux has a package manager called apt-get, which can be used to install a wide range of software, including Python libraries. To install a Python library using apt-get, follow these steps:
Step 1: Open the Terminal
To open the Terminal in Ubuntu, press the Ctrl + Alt + T keys on your keyboard.
Step 2: Update the package list
Before you can install a new package, you should update the package list by running the following command:
sudo apt-get update
Step 3: Install the Python library
To install a Python library using apt-get, you can use the following command:
sudo apt-get install <library-name>
For example, to install the numpy library, you would run the following command:
sudo apt-get install python3-numpy
Note that the name of the package may differ slightly from the name of the library. You can usually find the correct package name by searching for it using apt-cache search. For example, to search for the numpy package, you would run the following command:
apt-cache search numpy
This will return a list of packages that include the word “numpy” in the name.
Conclusion
Installing Python libraries in Ubuntu Linux is a straightforward process that can be done using either pip or apt-get. Pip is the default package manager for Python, and it allows you to easily install and manage Python libraries. Apt-get is the package manager for Ubuntu Linux, and it can also be used to install Python libraries. Whichever method you choose, make sure to update the package list before installing any new packages.
