mamba, an experiment to make conda faster

Still in BETA! Don't use mamba to install something in valuable environments!

Mamba is a reimplementation of the bits which are somewhat slow in conda. Mamba uses:

  • parallel downloading of JSON files using multiprocessing, and reusing conda's caches
  • libsolv for speedy dependency solving, a state of the art library used in the package manager of Fedora and others

At the same time, mamba re-uses a lot of conda's codebase to parse the command line and execute the transaction (installation & deinstallation of packages).

Installation

From conda-forge:

conda install mamba -c conda-forge

From Source:

Make sure to have the following requirements in your conda environment:

  • conda install pybind11 libsolv pip -c conda-forge

If you build mamba in a different environment than base, you must also install conda in that environment:

  • conda install conda -c conda-forge

For a local (dev) build, run pip install -e .. This will build and install mamba in the conda environment.

Now you are ready to install packages with mamba install xtensor-r -c conda-forge for example.
