    PyAutoGalaxy assumes that the `HowToGalaxy` directory is the Python working directory.
    This means that, when you run a tutorial script, you should run it from the `HowToGalaxy`
    repository root as follows:


    cd path/to/HowToGalaxy (if you are not already in HowToGalaxy).
    python3 scripts/chapter_1_introduction/tutorial_1_grids_and_galaxies.py


    The reasons for this are so that PyAutoGalaxy can:

    - Load configuration settings from config files in the `HowToGalaxy/config` folder.
    - Write simulated tutorial data to `HowToGalaxy/dataset/`.
    - Output the results of model fits to `HowToGalaxy/output/`.

    If you get errors relating to importing modules, loading data or writing output, it is
    most likely because you are not running the script with `HowToGalaxy` as the working
    directory.

    Figures produced by the tutorials are rendered with `matplotlib`. Depending on your
    system, you may need to configure the matplotlib backend. `tutorial_0_visualization.py`
    in `chapter_1_introduction` walks you through the options.
