You could use pixi instead, as a much nicer/saner alternative to conda: https://pixi.sh

Though in this particular case, you don't even need conda. You just need python 3.13 and a virtual environment. If you have uv installed, then it's even easier:

    git clone https://github.com/apple/ml-sharp.git
    cd ml-sharp
    uv sync
    uv run sharp
