allow switching to micromamba

[proppy]

I'd be nice to allow to point .install method to https://mamba.readthedocs.io/en/latest/user_guide/micromamba.html in order to speed up the installation process.

Thanks! Yes, this is planned in a future release. As a workaround, you can rely on mambaforge (default option) and use !mamba to install your packages.

We've thought about this and #31 implements a different strategy where we procure a new Python installation. Since we need ipykernel too, which requires Python anyway, using micromamba doesn't really offer much of an advantage over mamba. E.g. using micromamba to then install python, ipykernel and some other dependencies won't be faster than installing mambaforge to begin with.

Make sure to check the pre-release with !pip install -q https://github.com/conda-incubator/condacolab/archive/main.tar.gz and let us know how it goes!
