<b><i>Deep Learning for Imaging Cherenkov Telescopes Data Analysis.</b></i>
</p>
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.

## Implementation
### Dependencies
- PyTorch (>= 1.7)
- Numpy
- PyTables
- Matplotlib
- scikit-image
- PyTorch Lightning (>=1.4.6)
- TensorBoard
- IndexedConv (>=1.3)
- ctapipe
- dl1-data-handler
- lstchain (~0.7)

### Installation procedure
We recommend the use of [Anaconda](https://www.anaconda.com/products/individual) with Python 3.8.
Create the environment:
```
VERSION=0.8
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.lapp.in2p3.fr/GammaLearn/GammaLearn/-/tree/master/examples and some sample data in https://lapp-gitlab.in2p3.fr/GammaLearn/GammaLearn/share/data
To visualise the results from your experiment, GammaLearn integrates with
[GammaBoard](https://github.com/vuillaut/ctaplot) that provides high-level metrics and plots to assess IACTs reconstruction performances
To visualise the convolution kernels of your trained network (experimental feature)
```
gexplore-net path_to_your_experiments experiment_name checkpoint_version
```
