This page lists the Gammapy tutorials that are available as Jupyter notebooks.
You can read them here, or execute them using a temporary cloud server in Binder.
To execute them locally, you have to first install Gammapy locally and download
the tutorial notebooks and example datasets. The setup steps are described in
Getting Started. Once Gammapy installed, remember that you can always use
gammapy info to check your setup.

Gammapy is a Python package built on Numpy and Astropy, so for now you have to learn a bit of Python, Numpy and Astropy to be able to use Gammapy. To make plots you have to learn a bit of matplotlib.
We plan to add a very simple to use high-level interface to Gammapy where you just have to adjust a config file, but that isn’t available yet.
Here are some great resources:
- Python: A Whirlwind tour of Python
- IPython, Jupyter, Numpy, matplotlib: Python data science handbook
- Astropy introduction for Gammapy users | astropy_introduction.ipynb
- Astropy Hands On (1st ASTERICS-OBELICS International School)
