How to Install Anaconda on Windows correctly | Anaconda3-2020 Navigator with Python 3.8

This tutorial will cover step by step instructions to install Anaconda on Windows. You will also learn how to update, write your first program and uninstall Anaconda. This is going to be awesome learning, in case you are a developer or exploring Anaconda and Python.

Let's deep dive in with these topics -

What is Anaconda

Anaconda {a.ka. Anaconda Python} is a Python and R programming language distribution for scientific computing. All predictive analytics, data science, machine learning and big data falls under scientific computing.

It's helps to simplify package management and deployment. Anaconda is available for all platforms like Windows, macOS and Linux.

There are two version available to install Anaconda in Windows -

  1. Anaconda distribution or Individual edition, which are open source and free
  2.  Anaconda Team Edition and Anaconda Enterprise Edition are paid

In this tutorial, I will cover the Anaconda individual edition. It comes with more than 250 packages automatically installed and over 7500 packages available in the PyPI repository.

Conda is an open-source, language-agnostic and cross-platform package manager. It helps to manage and deploy packages using the command line while Anaconda navigator is a GUI alternative to Conda.

System requirement to Install Anaconda on Windows

  1. Internet connection
  2. Windows 10 machine
  3. Approx. 2.7GB free disks pace.

** You don't need python to be pre-installed because Python 3.8 automatically get install with Anaconda3.

Step1.3- Verify MD5 Checksum Keys for Anaconda installer

You need to perform this step to make sure you have a legitimate copy of Anaconda.

  • Visit "https://repo.anaconda.com/archive/" and search for your Anaconda installer.exe, which you just downloaded.
  • Look for the MD5 checksum Key written in the 4th column against your exe file.

For example, I will show MD5 Key for "Anaconda3-2020.11-Windows-x86_64.exe" in the image for reference.

Verify-md5-checksum

  • Now Type "Command prompt" in Windows search bar and open it as administrator.
Open-command-prompt-windows

  • Run the Certutil.exe command and provide the full path to your download file.
  • Add MD5 in the last of your command. You will get a series of number.
  • Match it with the key you got in Step1.3 from the Anaconda website. If all matches, you are good to proceed further.
C:\Windows\system32>certutil.exe -hashfile "path to your anaconda file" MD5

For example, I have added "C:\Users\Dev\Downloads\Anaconda3-2020.11-Windows-x86_64.exe" as the file path in the command.

Then I got 0841ffcb927a3c2edbd682520f52e546 MD5 Key. And If you will look closely, it matches with the key we noted in Step1.3.

> certutil.exe -hashfile "C:\Users\Dev\Downloads\Anaconda3-2020.11-Windows-x86_64.exe" MD5

#Output#
MD5 hash of C:\Users\Dev\Downloads\Anaconda3-2020.11-Windows-x86_64.exe:
0841ffcb927a3c2edbd682520f52e546

Step2.6- Choose Advance installation options

You have flexibility to customize your Anaconda integration with Windows. There are two options available -

a. Add Anaconda3 to my PATH variable - I will not recommend you to select this option. Because setting up the Anaconda PATH variable can mess up with your previously installed software. Alternatively, you can open Anaconda Shell or Navigator using the Windows start menu. Let's don't tick this check box.

b. Register Anaconda3 as my default Python 3.8 - You can go with this option because it helps other software to detect Python 3.8 as primary. If you don't want to set Python 3.8 as default, in case you are using some other python version. You can uncheck this option also.

I don't have any other software or Python installed. So I will leave "Register Anaconda3 as my default Python 3.8" selected.

Click on "Install" button to move further.

How to run Anaconda in Windows using CLI and GUI

When you install Anaconda on Windows, you get a lot of bundled scientific packages with it like Spyder, Python and Jupyter notebook.

There are two methods to run Anaconda in Windows. If you are a CLI (Command Line Interface) fan, you can use Conda to run on the prompt.

In the case of GUI (Graphical User Interface), an Anaconda navigator can be used to manage packages, environment and launch applications.

I will show you both methods (Conda and Navigator) to create your first program. Just follow along :--

Step3.1 (CLI Method) - Create and Activate Anaconda environment

Let's create our first test environment and run our first program in Python3.

Step3.1 (CLI Method) - Create and Activate Anaconda environment

To create your first environment, you need to launch Anaconda3 prompt application.

  • Type "Anaconda" in Windows search bar > Select Anaconda prompt application > Click Open
Run-Anaconda-prompt-CLI

Step3.1.2 - Activate conda environment

By-default, you will get base(root) environment in Anaconda shell prompt.

Run the "conda create" command to set up our first test environment (test_env) with Python3. It will also install the latest Python 3.9 and Pip 21.0 packages.

(base) C:\Users\Devender>conda create --name test_env python=3
Create-your-environment-using-Conda-create-command

Please make a note, every environment is individual in Anaconda. You need to install required packages for each environment individually.

Press "y" to install packages.

List-of-packages-to-install-in-environment

Anaconda will download, extract and install packages required. Once done, you can activate your environment with Conda activate command.

For example, test_env is the name of our newly create environment. So I will run this command -

(base) C:\Users\Devender>conda activate test_env

It will switch from base(root) environment to "test_env" environment as shown in image.

Activate-your-environment-using-conda-activate-command

** Please make a note running conda activate command without an environment name argument, drops you in the base environment. So make sure you give your environment name.

Step3.1.3 - Run your first python program

Now run Python and Type print("your first program") and check the output.

(test_env) C:\Users\Devender>python

You will get ">>>" prompt. Type print("Hello Anaconda! World") from your keyboard and press Enter.

# Type your first program code"
>>> print("Hello Anaconda! World")

Output should be "Hello Anaconda! World" as shown in image.

run-python-program-anaconda

Type exit() to come out from Python prompt.

Hurray!! You have run your first python program in Anaconda successfully.

Step3.1.4 - Deactivate Conda environment

If you want to exit or want to deactivate any environment. You just need to run conda deactivate command.

For example, If I will run conda deactivate command inside my test_env environment. It will drop me to the default base environment as shown in the image.

(test_env) C:\Users\Devender>conda deactivate
deactivate-your-conda-environment

Step3.2 (GUI Method)- How to start Anaconda navigator and Launch Jupyter

Just to make things interesting, I will show you how to Launch the Anaconda navigator. Also, how to install and launch Jupyter notebook using Anaconda in your newly created test environment.

So follow these easy steps -

Step3.2.1 - Launch Anaconda Navigator in Windows 10

  • Type "Anaconda Navigator" in Windows search bar > Select Anaconda Navigator > click Open.
Launch-anaconda-navigator

Step3.2.2 - Select your test environment (test_env) and install Jupyter notebook

Jupyter notebook is a web based tool to interactively develop and present data science projects.

You can launch Jupyter notebook from <start menu> or search bar also. But It will get launch from base(root) environment by-default.

Here I will show, how you can install and launch Jupyter notebook in your custom environment. For example, test_env in my case.

  • Select your environment from drop down > click on the "install" button in Jupyter Notebook application.
Select-environment-install-Jupyter-notebook

  • Please wait and let Jupyter notebook installation complete. You can monitor the progress in Navigator task bar.
Progress bar Jupyter install

Step3.2.3 - Launch Jupyter Notebook in Anaconda navigator

Click on Launch button of Jupyter notebook.

Launch-jupyter-notebook

You will see a Jupyter home page in your default web browser. The default URL path of Jupyter notebook will be http://localhost:8888/tree.
