Written in Python and C, Numpy<\/a> is a popular Python library used for scientific computing. It’s hugely popular in data science and a de facto standard for handling numerical data in Python programming. Numpy API is extensively used in other Python libraries such as matplotlib, SciPy, Pandas and so many more.<\/p>\n

In this guide, we will demonstrate how to install Numpy on Ubuntu 20.04.<\/p>\n

Step 1: Install PIP package manager<\/strong><\/h2>\n

The easiest route to install Numpy is to use the pip utility which is one of the most widely-used Python package managers. But first, update your system as shown.<\/p>\n

$ sudo apt update<\/strong><\/pre>\n
To install pip first ensure Python is installed. Thankfully, Python3 is installed by default in Ubuntu 20.04. You can confirm this by running the command:<\/p>\n
$ python3 -V<\/strong><\/pre>\n
OR<\/p>\n
$ python3 --version<\/strong><\/pre>\n
<\/strong><\/p>\n
Next, install pip3 <\/strong>as follows:<\/p>\n
$ sudo apt install python3-pip<\/strong><\/pre>\n
<\/p>\n
Once installed, confirm the version of pip installed:<\/p>\n
$ pip3 --version<\/strong><\/pre>\n
This displays not only the version of PIP but also the binary location of the package.<\/p>\n
<\/p>\n
Step 2: Install Numpy on Ubuntu 20.04<\/strong><\/h2>\n
With PIP installed, the next course of action is to install Numpy. To do this, execute the command:<\/p>\n
$ sudo apt install python3-numpy<\/strong><\/pre>\n
<\/p>\n
When the installation of Numpy is done, verify the version of Numpy installed as follows<\/p>\n
$ python3 -c \u201cimport print; print(numpy.__version__)\u201d<\/strong><\/pre>\n
<\/p>\n
Alternatively, you can access the Python shell:<\/p>\n
$ python3<\/strong><\/pre>\n
Import Numpy<\/p>\n
>>> import numpy<\/strong><\/pre>\n
Next, check the version of Numpy installed:<\/p>\n
print(numpy.__version__)<\/strong><\/pre>\n
Note that the underscores are double underscores and not single underscores.<\/p>\n
<\/p>\n
If you wish to upgrade Numpy in the future, simply run:<\/p>\n
$ pip3 install --upgrade numpy<\/strong><\/pre>\n
Conclusion<\/strong><\/h2>\n
And there you go! We have successfully installed Numpy on Ubuntu 20.04. Your thoughts and feedback on this guide are welcome.<\/p>","protected":false},"excerpt":{"rendered":"
