Pixi is a fast, modern, and reproducible package management tool for developers of all backgrounds.

Installation

https://pixi.sh/latest/installation/

To install pixi you can run the following command in your terminal:

Linux & macOS

curl -fsSL https://pixi.sh/install.sh | sh

If your system doesn’t have curl, you can use wget:

wget -qO- https://pixi.sh/install.sh | sh

What does this do?

The above invocation will automatically download the latest version of pixi, extract it, and move the pixi binary to ~/.pixi/bin. The script will also extend the PATH environment variable in the startup script of your shell to include ~/.pixi/bin. This allows you to invoke pixi from anywhere.

Now restart your terminal or shell to make the installation effective.

Windows

Download the MSI installer: https://github.com/prefix-dev/pixi/releases/latest/download/pixi-x86_64-pc-windows-msvc.msi

OR:

Or run:

powershell -ExecutionPolicy ByPass -c "irm -useb https://pixi.sh/install.ps1 | iex"

What does this do?

The above invocation will automatically download the latest version of pixi, extract it, and move the pixi binary to %UserProfile%\.pixi\bin. The command will also add %UserProfile%\.pixi\bin to your PATH environment variable, allowing you to invoke pixi from anywhere. Now restart your terminal or shell to make the installation effective.

Installing packages and running commands

For more backround, please read the manual: https://pixi.sh/latest/getting_started/

From here you would use pixi for installing additional packages or creating environments with an environment.yml file.

The next step is creating environments and install packages into into your folder-based flexible Python working environment. For here you should know what you are doing, as this is different from the micromamba/conda approach documented for this workshop.

Check out the 4. Creating environments and install packages page to see which packages are needed.

Then, set up the JupyterLab notenook environment with Pixi.

Check out the 5. Setting up Jupyter Notebook page to see for the Micromamba approach.
