Mamba

module avail mambaforge/

Mamba is an open-source package management and environment management system that is commonly used in the Python programming ecosystem.

Mamba is a re-implementation of Conda written in C++, offering some benefits.

  • Parallel downloading of repository data and package files using multi-threading.
  • Libsolv for much faster dependency solving.
  • C++ implementation for maximum efficiency.

The syntax of mamba commands is basically the same as that of Conda. Mamba utilises the same command line parser, package installation code and transaction verification routines as conda to stay as compatible as possible.

Tip

We would like to encourage users to use Mamba as a primary tool to invoke and install environments. Module mambaforge can even access environments installed in conda-modules, and thus can act as a full replacement of conda-modules module.

Warning

Avoid combining Mamba environments with traditional modules in a single session. Doing so can often lead to conflicts and application malfunctions.

Usage

Use existing environment

The basic commands are:

module add mambaforge     # load the module
mamba env list            # list installed environments
mamba activate busco      # activate an environment (e.g. busco)
mamba --help              # use selected application
mamba deactivate          # quit

Install new environment

See How to install Conda/Mamba packages.
