Cloning environment with micromamba

It seems micromamba is missing a clone environment option, or is it just named differently?

  • Mamba's help micromamba create -n envname --help does not seem to show any clone-like option and
  • standard conda's conda create -n envname --clone oldenv doesn't seem to work.

If mamba is missing clone option, what is the reason for that?

Thanks!

Solution

  • Yeah, It does not have a cloning option yet

    Minor Update

    the command to create the environment failed with micromamba version 1.4.9, use the --file flag,

    micromamba env create --name newenv --file oldenv.yaml

    -- informed by gkaf

    REASON:

    It's simply because it is designed as a lightweight, fast, and minimal version of mamba. The clone environment is a relatively complex feature, and it was not considered to be essential for the core functionality of micromamba.

    SOLUTION:

    There is a roundabout way although. As per I know, you can export the current env as yaml and run micromamba env create to create a env from the yaml file.

    Export the contents of the existing environment to a YAML file.

    micromamba env export -n oldenv > oldenv.yaml

    Create a new environment from the YAML file.

    micromamba env create -n newenv -f oldenv.yaml

    This should work, notify if it doesn't.
