Miniforge Installation

An easy and flexible way to use Python is through Miniforge (a lightweight version of Conda-Forge). This allows users to have a fully-featured Python environment under their own control. Below is an example of how to set up Miniforge in the user's home directory.

Code Block
$ wget "https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname -m).sh"
$ bash Miniforge3-$(uname)-$(uname -m).sh

# During the installation, ***do NOT init***, as we will do it properly later.
You can undo this by running `conda init --reverse $SHELL`? [yes|no]
[no] >>> no

# To use the conda command, you need to add the ~/miniforge3/condabin directory to 
# the PATH environment variable. Some old guides use "conda init" but it seems to point
# conda not mamba. To setup mamba properly:
$ ~/miniforge3/condabin/mamba init

# Prevent auto activate the base env. True this is confusing, you need to use conda
# here.
$ conda config --set auto_activate_base false
Note

The use of Miniforge/Conda may consume lots of disk space (for installed packages and downloaded cache). Please watch out for your home directory space quota.

CSG Managed Miniforge

A CSG-managed Miniforge installation is also available at the following path:

Code Block
/share/apps/noarch/miniforge3/

This central installation provides popular and commonly used environments, ready for immediate use by everyone. It helps avoid duplication and conserves users' disk space.

Code Block
$ /share/apps/noarch/miniforge3/condabin/mamba env list
# conda environments:
#
                         /import/reed/8/z3155686/miniforge3
                         /import/reed/8/z3155686/miniforge3/envs/dice
                         /import/reed/8/z3155686/miniforge3/envs/discourse
base                     /share/apps/noarch/miniforge3
pytorch_cu118            /share/apps/noarch/miniforge3/envs/pytorch_cu118
pytorch_cu121            /share/apps/noarch/miniforge3/envs/pytorch_cu121
Info

The Miniforge environment specification files are managed via Git: miniforge3_env.git. If you'd like to share your environment, please contact us, and we can add it to the managed Miniforge.
