Anaconda is an open-source package and environment manager that houses thousands of predictive analysis, machine learning, and data science packages. Its purpose is to provide scientific libraries and dependencies for Python programmers. Anaconda is frequently used for the development of machine learning and artificial intelligence applications.
Anaconda makes package distribution and administration easier. It comes with various tools such as conda and Jupyter Notebook that provide you with a smooth and fast package and environment development. Anaconda also supports the creation of a basic, controllable environment, making any project deployment straightforward.
Here at Ibmi Media, we shall look into how to install, use, and remove Anaconda from your Ubuntu operating system.
Steps to install Anaconda on your Ubuntu 20.04
1. Install Dependency Packages
To use Anaconda Navigator, you need to install the following packages. Anaconda Navigator is a QT-based graphical interface that is highly convenient on the desktop:
$ sudo apt install libgl1-mesa-glx libegl1-mesa libxrandr2 libxss1 libxrandr2 libxcursor1 libasound2 libxcomposite1 libxi6 libxtst6
2. Download the Anaconda Installation File
Next, download the installation file for Anaconda using the following wget command:
$ wget -P /tmp https://repo.anaconda.com/archive/Anaconda3-2021.11-Linux-x86_64.sh
It is recommended to take and compare the SHA256 hash of the downloaded file with the official file HASH to prove that your file is authentic.
Use the following SHA256sum command to get the hash of the downloaded file:
$ sha256sum /tmp/Anaconda3-2021.11-Linux-x86_64.sh
3. Install Anaconda
Run the downloaded shell script and install Anaconda using the following bash command:
$ bash /tmp/Anaconda3-2021.11-Linux-x86_64.sh
During installation, you will be prompted to accept the license terms. Type yes to proceed.
Next, select the location of the installation and hit Enter.
Once installation is finished, Initialize the anaconda using the conda init by typing yes and proceed. Conda is a command-line package manager for Anaconda. Conda inti will not only initialize the anaconda, but it will also add itself to the system variable PATH.
Run the following command to fetch your bashrc file:
$ source ~/.bashrc
Type conda or conda info in your terminal to verify anaconda installation.
