Install Conda: Mamba

This guide provides instructions for installing Mamba into a custom directory, without conflicting with local site packages, creating a Python environment, and activating it.

Overview

  • Mamba is fast envrionment solver. We recommend using this.

    Note

    User can use standard anaconda or miniconda as well.

Install Mamba in a Custom Directory

  1. Download the Installer

    wget https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-Linux-x86_64.sh

  2. Install into a Custom Directory

    Replace /path/to/conda3_custom with your desired location:

    bash Miniforge3-Linux-x86_64.sh -b -p /path/to/conda3_custom

    Note

    In HPC cluster, it is recommended to set /path/to/conda3_custom to a location which is accessible by all nodes and with fast disk speed. Read you HPC documentation carefully and check whether conda is already installed and available as module or not.

  1. Enable the ‘conda’ Command

    Important

    To avoid using the full path (/path/to/conda3_custom/bin/conda) every time, do the follwing:

    /path/to/conda3_custom/bin/conda init
source ~/.bashrc    # or ~/.zshrc, depending on your shell

    After this, conda will be available as a global command.
