Ch 3 Introduction to tools for AI Class 9 Notes Important Points

Introduction

In Chapter 1 and Chapter 2, we have already studied about algorithms, flowcharts and Python programming. Now, in this chapter we’ll explore two important tools in Python for AI – Anaconda and Jupyter Notebook which will help us with better understanding and faster debugging of codes.

What is Anaconda?

Anaconda is a free and open-source distribution of the Python language which is used for scientific computing. It provides the facility to create different virtual environments, each having its own packages and settings, as per user’s need.

Why do we need Anaconda?

Whenever we are working in AI, we use different packages of python like Numpy, Pandas etc. To install all of them may create confusion so Anaconda make it simple by creating virtual environment of each project separately.

What is Anaconda Navigator?

It is a desktop graphical user interface(GUI) included in Anaconda that helps us

To launch applications
Manage conda packages, environments and channels

without the need to use command line commands.

Interesting Fact 1: The name Anaconda was chosen because it can handle large scale data just like snake handles large meals

How to install Anaconda? or Anaconda Installation Steps

Following are the steps of how to download and install Anaconda for windows.

Step 1: Log on to https://www.anaconda.com/distribution/

Step 2: Scroll down and click on windows.

Tools for AI — **Steps to install Anaconda**

Step 3: Select the right option according to the configuration of your pc(32-bit/64-bit).

Step 4: Double click the installer to launch.

Step 5: Click on “Next”.

Step 6: Read the license agreement and click on “I Agree”.

Step 7: Select an install for “Just Me” unless you’re installing for all users (which requires Windows Administrator privileges) and click “Next”.

Step 8: Select destination folder, and click “Next”.

Step 9: Do not change anything in PATH Options, click “Next”.

Step 10: Wait for the installation to complete.

Step 11: Click on “Skip” to continue.

Step 12: Click on “Finish”. Your Anaconda setup is complete!

Anaconda Prompt- Anaconda’s Command Line Interface.

Anaconda Prompt is a Python Command Line Interface(CLI ) where we can create different virtual environments and install packages into them as per our need.
We can open Anaconda prompt by writing “Anaconda Prompt” in windows search bar.

NOTE: When we open Anaconda prompt, the (base) is written at the beginning of the line, it shows that default environment is active.

Jupyter Notebook

Jupyter Notebook is an open source web application that you can use to create and share documents that contain live code, equations, visualizations, and text.

Interesting Fact 2: The word “Jupyter” comes from Julia, Python and R – These are three main programming language used for data science.

What is Notebook?

A notebook is a tool which combine code and its output into a single document that combines visualizations, narrative text, mathematical equations, and other rich media.

Installing Jupyter Notebook

The easiest way to install and start using Jupyter Notebook is through Anaconda as it comes pre-loaded with all the most popular libraries and tools.

Working with Jupyter Notebook

Working with Jupyter notebook requires a kernel on which it operates. A kernel provides programming language support in Jupyter. IPython is the default kernel for Jupyter Notebook.

To install the kernel, Open Anaconda Prompt and execute the following command:

conda install jupyter nb_conda ipykernel

Once the installation is done, write the following command to open the Jupyter Notebook.

jupyter notebook

The Jupyter Notebook opens in the default browser with http://localhost:8888/tree URL.

In this page, click on New (right top corner) and select Python3 which would open a new Jupyter notebook with Python3 as the default language as shown below

Interesting Fact 3: Around 80% of companies today use AI in some form — from chatbots to automatic translation.

Jupyter Notebook Interface

Jupyter Notebook is a Graphical User Interface (GUI) which means that the Notebook interface contains a lot of tools which make my work easier.

Features of Notebook: Jupyter Notebook has two main parts:

1. Menu bar

Jupyter Notebook Menu bar contains the following options:

File Menu: In this menu, there is an option to create a new Notebook or open a pre-existing Notebook. I think the most interesting menu item is the Save and Checkpoint option which allows us to create checkpoints that we can roll back to if required.

Edit Menu: This menu help us to

Cut, Copy, and Paste cells.
Delete, Split, or Merge a cell.
Reorder cells here too.

View menu: This menu is helpful in

Toggling the visibility of the header and toolbar.
Toggle Line Numbers within cells.

Interesting Fact 3: AI can even compose music, draw pictures, and write code using tools like ChatGPT and DALL·E!

Insert menu: This menu is helpful in inserting cells above or below the currently selected cell.

Cell menu: This Cell menu allows you

execute one cell, a group of cells, or all the cells.
to change a cell’s type.
to clear a cell’s output.

Kernel Menu: It helps to restart the kernel, reconnect to it, shut it down, or even change which kernel our Notebook is using.

Widgets Menu: The Widgets menu is for saving and clearing widget state. (Widgets are basically JavaScript widgets that we can add to our cells to make dynamic content using Python)

Help Menu: This menu helps to

learn about the Notebook’s keyboard shortcuts
a user interface tour, and lots of reference material.

2. Toolbar in Notebook interface.

Let we discuss each of the tools.

Summary

Anaconda	It is a free and open-source which manages Python packages & environments
Navigator	It is a graphical user interface included in Anaconda that allows you to launch tools
Jupyter Notebook	Runs live code interactively
Kernel	It helps to connects Python code with notebook
Menu & Toolbar	It contains different options which make our interface simpler for coding
