Enhancing the Data-Analysis Pipeline of Gamma-Ray Telescopes with Machine Learning

Setup Option 1: Full Installation

Prerequisites:

• Make sure you have all development tools installed on your computer, such as python3, git, cmake, etc.
• On macOS only the python version downloaded from python.org will work, or the ones coming with brew or macports
• April 2022: Python 3.9 and 3.10 do not yet work with tensorflow on M1 macs

Install MEGAlib -- but only if it is required for your specific tool:

Follow these instructions, to install MEGAlib.

Get the code

To get the code, just clone the git repository:

git clone https://github.com/zoglauer/gamma-ai COSIMachineLearning

Creating the environment

One of the required packages is at the moment only available via pip, not any other python package manager. In addition we need specific versions of some popular packages such as numpy. Therefore, we will have to setup a virtualenv environment to run our specific python version. In the COSIMachineLearning directory, do:

bash setup.sh

This will create a python environment in python-env, activate it, and install all required packages.

Using it

Remember to activate your python environment whenever you are switching to a new bash shell:

. python-env/bin/activate

Now you are ready. Switch to the example directory, and take the example to a test drive!

Setup Option 2: Docker

This guide will show you how to install and run the tools via a preconfigured docker image.

Get the source code

To get the code, just clone the git repository:

git clone https://github.com/zoglauer/bids-discovery MachineLearning

Please remember the full you have cloned the repository to, since you will need it later.

Install docker and download the docker image

Please follow the guide here to install the latest MEGAlib docker image: Docker setup

Running the docker image

To run the docker image do (replace /path/to/MachineLearning with the full path of the directory into which you have cloned this repository, and TAG with the tag of the downloaded docker image, e.g. 2.99.11):

On Linux:

docker run -v /path/to/MachineLearning:/home/mrmegalib/exchange -e DISPLAY=$DISPLAY -e USERID=`id -u ${USER}` -e GROUPID=`id -g ${USER}` -v /tmp/.X11-unix:/tmp/.X11-unix -it zoglauer/megalib:TAG

On Mac:

YOURIP=$(ifconfig | grep "inet " | grep -v 127.0.0.1 | awk '{ print $2 }')
xhost + ${YOURIP}
docker run --rm -it -v /path/to/MachineLearning:/home/mrmegalib/exchange -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=${YOURIP}:0 -e USERID=`id -u ${USER}` -e GROUPID=`id -g ${USER}` zoglauer/megalib:TAG
