How to install Anaconda in Manjaro Linux

Anaconda is a distribution of the python and R programming languages for scientific computing, that aims to simplify package management and deployment.

Anaconda is a solution for data science and machine learning, it’s very versatile. The reason many love Anaconda is:

• Can deliver your data strategy easily
• It maximizes flexibility and control
• Products get to the market faster

Install Anaconda

It is recommended that when installing Anaconda, don’t install using AUR packages, because AUR installs to the /opt directory which requires root to execute and Anaconda wants only the user with Sudo privileges.

1. Update system repositories

To update the Manjaro Linux we use the following command.

sudo pacman -Syu

2. Install Gui dependencies

We need to install the following packages to enable us to be in a position to use Gui functionalities. Go to your terminal and run the following

sudo pacman -Sy libxau libxi libxss libxtst libxcursor libxcomposite libxdamage libxfixes libxrandr libxrender mesa-libgl  alsa-lib libglvnd

2. Download Anaconda for Linux

Go to this link in order to download the latest distribution of Anaconda

wget https://repo.anaconda.com/archive/Anaconda3-2022.10-Linux-x86_64.sh

After the download is complete, proceed to check the authenticity of the Anaconda with the use of the following sha script. Make sure you are in the directory you downloaded your Anaconda.

$ shasum -a 256 Anaconda3-2022.10-Linux-x86_64.sh
e7ecbccngtxs6577ebd7e1f211c59df2e37bc6959f2235d387e08c9026666acd  Anaconda3-2022.10-Linux-x86_64.sh

3. Install Anaconda

Now, let’s start installing Anaconda with the use of bash. Make sure you have Python 3.7 and above.

bash Anaconda3-2022.10-Linux-x86_64.sh

Accept all the prompts given in the process for Anaconda to begin the installation.

    Installed package of scikit-learn can be accelerated using scikit-learn-intelex.
    More details are available here: https://intel.github.io/scikit-learn-intelex

    For example:

        $ conda install scikit-learn-intelex
        $ python -m sklearnex my_application.py
done
installation finished.
Do you wish the installer to initialize Anaconda3
by running conda init? [yes|no]
[no] >>> yes

==> For changes to take effect, close and re-open your current shell. <==

If you'd prefer that conda's base environment not be activated on startup, 
   set the auto_activate_base parameter to false: 

conda config --set auto_activate_base false

Thank you for installing Anaconda3!

4. Activate the virtual environment

Anaconda needs to be run in a virtual environment in order to isolate its working environment with your system to avoid installing dependencies globally.

To activate you may use of the following command

source <path to conda>/bin/activate

If you’d prefer that conda’s base environment not be activated on startup, set the auto_activate_base parameter to false: I will prefer this option because I run other processes with my machine.

conda config --set auto_activate_base false

Verify that conda has been installed with the following command.

conda list

You will be in a position to see many packages installed.

# packages in environment at /home/sang-pc/anaconda3:
#
# Name                    Version                   Build  Channel
_ipyw_jlab_nb_ext_conf    0.1.0            py39h06a4308_1

anaconda-client           1.11.0           py39h06a4308_0  
anaconda-navigator        2.3.1            py39h06a4308_0  
anaconda-project 
....

You can also use python command to verify Anaconda.

$ python
Python 3.9.13 (main, Aug 25 2022, 23:26:10) 
[GCC 11.2.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 

Another way to verify is to use anaconda-navigator, this will open a GUI application.

anaconda-navigator

Uninstall Anaconda

To fully uninstall Anaconda from your system, use the following command.

conda install anaconda-clean

Follow the promts in order to run uninstaller

Collecting package metadata (current_repodata.json): done
Solving environment: done

## Package Plan ##

  environment location: /home/sang-pc/anaconda3

  added / updated specs:
    - anaconda-clean


The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    anaconda-clean-1.1.1       |   py39h06a4308_0           8 KB
    ------------------------------------------------------------
                                           Total:           8 KB

The following NEW packages will be INSTALLED:

  anaconda-clean     pkgs/main/linux-64::anaconda-clean-1.1.1-py39h06a4308_0 None
Proceed ([y]/n)? y

Then we need to use anaconda-clean we have installed above to remove all the Anaconda packages. If you don’t want to be asked about each file and directory append --yes

anaconda-clean --yes

Then we need to remove the backup files made by anaconda from our system with the following command

rm -rf anaconda3

Conclusion

We have successfully installed Anaconda on Manjaro Linux. Go ahead and experiment with it now.
