What is Scipy in Python?

The Scipy (Scientific Python) is an open-source library that helps in the computation of complex mathematical or scientific problems. It has a built-in mathematical function and libraries that can be used in science and engineering to resolve different kinds of problems.

Also, It has built-in algorithms for optimization, eigenvalue problems, differential equations, integration, interpolation, algebraic equations, statistics, etc.

The Scipy is the extension of Numpy (Numerical Python), the data processing is extremely fast and efficient. The Scipy is written languages C, C++, Fortran and Python.

The high-level commands and classes provide an easy way for data manipulation and visualization. It can integrate with many different environments and has a huge collection of sub-package for scientific domains.

Why we use Scipy in Python

The Scipy contains the optimized functions that are used in Data Science and other engineering domains and it is an extension of Numpy. It can perform many different kinds of Scientific computation and deal with different Scientific problems.

Difference between Scipy and NumPy

The Scipy and Numpy are very essential libraries with a huge and wide range of functions or methods in Python. The difference between Scipy and Numpy is given below.

Difference based on	Scipy	Numpy
Functions	It has different kinds of functions with very details.	It has different kinds of functions with fewer details.
Operations	It performs complex operations like numerical algorithms and algebraic functions.	It does basic operations like indexing, sorting, etc.
Speed and language	Scipy is written in Python, so it has a slower speed with huge functionality.	The base language of Numpy is C, so it has faster computational speed.
Arrays	It is a function-based library, so here there is no concept of an array.	There is the concept of arrays in Numpy, It can build a multidimensional array of objects that contains the same kind of data.

Installation of Scipy

Here we will install the Scipy on the two systems Windows and Linux by following the below steps.

Before installing Scipy make sure that Python is already installed on your system, If you want to install then visit our another tutorial “Python download and Installation steps (Windows 10/Unix/Mac/Ubuntu/CentOS )”.

Installation of Scipy using pip on Windows

First, we are going to install the Scipy on Windows using the Python package manager 'pip' that helps in modifying the existing packages, installing packages, and removing unnecessary packages.

Open a command line and run the command which is shown below to install the Scipy.

pip install scipy

After running the above command, A Scipy is installed successfully on your system as shown in the below output.

To check the version of Scipy, open the command line type the below code to enter into the python interpreter.

How to import scipy in Python

Now, once the Scipy package is successfully installed, the next step is to start using it. And for this task, first, we need to import it. We can import the package Scipy using the following command.

import scipy

Check the version of installed Scipy.

scipy.version.version

The output shows the current version of Scipy is 1.8.0.

Installation of Scipy using pip on Linux

Here we are going to install the Scipy on the Linux system using the Python package manage pip.

First, install the pip by running the below command in a terminal.

sudo apt install python3-pip

Again, open a terminal or in the same terminal and enter the below command to install the Scipy.

pip install scipy

Here, the above code installs the Scipy on our system.

To check the version of Scipy, open the command line type the below code to enter into the python interpreter.

python3

Import the package Scipy.

import scipy

Check the version of installed Scipy.

scipy.version.version

The above output shows the installed version of Scipy is 1.8.0.

Installation of Scipy Using Anaconda

Here we will install the Scipy in Anaconda using the two methods command line and Anaconda Navigator.

#1 Command Line

On your system search the Anaconda Prompt in using the search bar of Windows and click on that as shown in the below picture.

Check the python version by typing the below command in that prompt.

python --version

Then install the Scipy using the below command.

pip install scipy

To check the version of Scipy, open the command line type the below code to enter into the python interpreter.

python3

Import the package Scipy.

import scipy

Check the version of installed Scipy.

scipy.version.version

#2 Anaconda Navigator

Open the search bar on your system and type anaconda navigator in the search bar, then click on that to open as shown in the below output.

After opening Anaconda Navigator click on Environment tab from the left side paned and select your primary environment as here selected base (root).

Then select the option Not installed as shown in the below picture.

After performing the above steps, search the Scipy by typing in the Search Packages bar located at the top right corner and selecting the packages as shown in the below output.

After selecting, the package clicks on Apply button as shown in the below picture.

After clicking on button Apply, a Scipy package is installed as shown in the below picture.

Pip Update Scipy

When we run the command pip update scipy to update the SciPy version to the latest version on windows, it shows an error that unknown command update.

To update SciPy to the latest version use the right command which is shown below.

pip install --upgrade scipy

This is how to update the SciPy version to the latest version using the command pip install --upgrade scipy.

Import Scipy As

To use the SciPy libraries or methods, first, we need to import the SciPy module, there are different ways to import the SciPy library.

The first is to import the library directly using the import command as shown in the below code.

import scipy

Now access any module that exists in the SciPy library using the below code.

scipy.linalg.inv

Again import the SciPy library with a different name using the below code.

import scipy as sp

In the above code, we are importing the library SciPy with name sp, this name is called alias name. We can use any name of our choice.

Let’s access the module or methods of SciPy using the alias name.

sp.linalg.inv

This is how to import the SciPy library using the command import scipy as sp.
