GammaLearn

Deep Learning for Imaging Cherenkov Telescopes Data Analysis.

GammaLearn is a collaborative project to apply deep learning to the analysis of low-level Imaging Atmospheric Cherenkov Telescopes such as CTA. It provides a framework to easily train and apply models from a configuration file.

Installation procedure

We recommend the use of Anaconda with Python 3.8.

Create the environment:

VERSION=0.12.0
wget https://gitlab.in2p3.fr/gammalearn/gammalearn/-/raw/v${VERSION}/environment.yml -O glearn_${VERSION}_env.yml
conda install mamba -n base -c conda-forge
mamba env create -f glearn_${VERSION}_env.yml
conda activate glearn

Note for OSX and/or no-gpu users: please edit the environment file to remove cudatoolkit from the dependencies.

Install GammaLearn

• with pip (recommended for users)

pip install gammalearn==$VERSION

• or from source (for developpers):

git clone --depth 1 https://gitlab.in2p3.fr/gammalearn/gammalearn
cd gammalearn
pip install .

Usage

First activate your conda environment

To run an experiment

gammalearn path_to_your_experiment_settings_file.py

you can find an example of setting file in https://gitlab.in2p3.fr/gammalearn/gammalearn/-/tree/master/gammalearn/data/example_settings and some sample data in https://gitlab.in2p3.fr/gammalearn/gammalearn/-/tree/master/share/data

To visualise the results from your experiment, GammaLearn integrates with GammaBoard that provides high-level metrics and plots to assess IACTs reconstruction performances

To visualise the convolution kernels of your trained network (experimental feature)
