6  Python installation guide

Before proceeding, install Python from the company portal. If you are using a private computer, download the latest version of Python for your operating system from python.org, and select “Add Python.exe to PATH” . Use the three tabs below to select which type of computer you are using, university or private, windows or unix.

6.1 Virtual environment

JU computer

Search for and start cmd.exe using the start menu, then run the following:

G:\
python -m venv venv

Private computer (windows)

Search for and start cmd.exe using the start menu, then run the following:

cd /d %UserProfile%
python -m venv venv

Private computer (unix)

Search for and start Terminal using the application launcher, then run the following:

python -m venv venv

This will create a new folder called venv in the current directory which contains a fresh python installation. Once the above command has finnished running, “step into” the virtual environment with:

JU computer

cd venv
cd Scripts
activate.bat

Private computer (windows)

cd venv
cd Scripts
activate.bat

Private computer (unix)

source venv/bin/activate

The text (venv) should appear to the bottom left in the terminal after running the above command. Now use the Python package manager pip to install the tools that we are going to use:

pip install marimo numpy sympy matplotlib

This command can take some time to run. While you wait for it to finish, you can proceed to the next step which describes how to create a shortcut. This shortcut will be all you need to start marimo notebook in the future.

6.2 Shortcut

Start your favourite text-editor and put the following contents in a new file:

JU computer

call G:\venv\Scripts\activate.bat
marimo edit

Save the file as START_MARIMO.bat somewhere easily acessible, and make sure that you selected “All files” instead of “text files” before you press save.

Private computer (windows)

call %UserProfile%\venv\Scripts\activate.bat
marimo edit

Save the file as START_MARIMO.bat somewhere easily acessible, and make sure that you selected “All files” instead of “text files” before you press save.

Private computer (unix)

#!/bin/bash
source ~/venv/bin/activate && marimo edit

Save the file as start_marimo.sh somewhere easily acessible, and then run:

chmod +x start_marimo.sh

Wait for the pip install command to finish running, then double click your shortcut to start the notebook.
