How to install Anaconda

How to install Anaconda¶

Prerequisite¶

ROS needs to install first

Step-by-step process¶

Step1: go to the anaconda website: https://www.anaconda.com/products/individual#Downloads
Step2: Navigate to your Downloads folder and type the follow command:

bash Anaconda3-2020.11-Linux-x86_64.sh

Step3: Now when you try to type the following command to launch anaconda:

anaconda-navigator

You will get response "command not found"

Use the following command to add the anaconda3 paht to environment:

export PATH=/home/yourusername/anaconda3/bin:$PATH

Now you can manually launch anaconda-navigator from your terminal

Step4: Create Anaconda Navigator shortcut/icon. You can check the website. I will put the simplified steps here:
Use your terminal and go to your Desktop and create
```
cd Desktop
gedit anaconda-navigator.desktop
```

In your text editor and enter following contents

Replace zhz03 to your username

#!/usr/bin/env xdg-open
[Desktop Entry]
Name=Anaconda
Version=2.0
Type=Application
Exec=/home/nxp/anaconda3/bin/anaconda-navigator
Icon=/home/nxp/anaconda3/lib/python3.8/site-packages/anaconda_navigator/static/images/anaconda-icon-256x256.png
Comment=Open Anaconda Navigator
Terminal=false

Copy this file to your application folder

cp anaconda-navigator.desktop ~/.local/share/applications/

Now you'll see your Anaconda navigator on your application menu/list
Step 5: conda init for your bash

after you run:

export PATH=/home/yourusername/anaconda3/bin:$PATH

You can initialize conda in your terminal by running:
```
conda init
```
It’s recommended that you disable automatic activation of the conda base environment by running:
```
conda config --set auto_activate_base false
```

How to install miniconda¶

Difference between anaconda and miniconda¶

The main difference between Anaconda and Miniconda lies in their size and the number of pre-installed packages. Anaconda is larger and comes with a vast array of pre-installed packages, while Miniconda is smaller and only includes Conda and Python.

Step-by-step process¶

Step1: Download miniconda installation script:

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh

Step2: Install miniconda into specific location

sudo bash Miniconda3-latest-Linux-x86_64.sh -b -p /opt/miniconda3

This will install miniconda into /opt/miniconda3

Step3: setup environment path

export PATH="/opt/miniconda3/bin:$PATH"
