Different Ways of Installing Python’s Numpy on Linux

Last Updated : 08 Oct, 2021

Numpy is a python library that is very popular in the field of data science because it makes the task of data processing very efficient, unlike conventional arrays. If you want to learn more about Numpy, please refer to this article.

Before we start with the installation steps, we have to make sure that your system has python installed.

Type the following command in the terminal (To open the terminal, press Ctrl + Alt + T)

$ python --version

If the output of the command is a valid python version, then you have python installed in your system.

Example Output:

Python 3.8.10

But if you don’t have Python installed in your system, there’s nothing to worry about. You can install Python using the following commands.

$ sudo apt-get update
$ sudo apt-get install python3

Now that you have successfully installed python in your system, we can start installing Numpy

Method 1: Using PIP to install NumPy on Linux

Follow the below steps to install Numpy on Linux:

Open a new terminal

Enter the following command in your terminal

$ pip install numpy

After the installation is complete, you can test if it was correctly installed using the following commands.

$ pip show numpy

Using PIP to install NumPy on Linux

There is an alternate way of checking

$ python

>>> import numpy as np
>>> np.__version__

Example Output:-

'1.17.4'

Method 2: Using Anaconda-Navigator to Install Numpy on Linux

Follow the below steps to install Numpy using anaconda-Navigator:

Open a new terminal window and enter the command given below

$ anaconda-navigator

Anaconda Navigator

After the Anaconda-Navigator is finished loading click on the Environments tab
Now we will create a virtual environment to install Numpy but if you don’t want to do that you can just install Numpy in your base(root) environment by skipping the steps of creating a virtual environment
Click on the “Create” button at the bottom of the navigator

Now choose a name for your virtual environment and a Python version then click on “Create”

Select your virtual environment and search for “Numpy” in the search bar

Click on Apply

Using Anaconda-Navigator to Install Numpy on Linux

Again click on apply and wait for the completion of the installation process
Now we will check if the installation was successful or not
Click on the PLay button next to the name of your virtual environment and choose “Open Terminal”
