Usage

Installation

To use easyfermi, first install the fermitools environment using mamba (or conda):

$ mamba create --name easyfermi -c conda-forge -c fermi python=3.9 "fermitools>=2.2.0" "healpy=1.16.1" "gammapy=1.1" "scipy=1.10.1" "astropy=5.3.3" "pyqt=5.15.9" "astroquery=0.4.6" "psutil=5.9.8" "emcee=3.1.4" "corner=2.2.2"

Then activate the environment and install fermipy and easyfermi:

$ mamba activate easyfermi
$ pip install fermipy easyfermi

• (ONLY FOR WINDOWS) Install the libgl1 package:

$ sudo apt-get install libgl1

• If you want, you can set easyfermi as an environmental variable. For instance, if you use a Bash shell environment, you can open the .bashrc file in your home and set:

$ alias easyfermi="mamba activate easyfermi && python -c 'import easyfermi'"

substituting miniforge and mamba by e.g. anaconda and conda if needed. This line of command depends on which distribution of Python you installed and how you set up the mamba/conda environment.

Upgrading

You can check your currently installed version of easyfermi with pip show:

$ pip show easyfermi

If you have easyfermi 2.0.X installed, upgrade your installation to the latest version by running the following command in the easyfermi environment:

$ pip install easyfermi --upgrade --no-deps

If instead, you have easyfermi 1.X.X installed, please install easyfermi V2 following section Installation.

Uninstalling

In the terminal, run:

$ mamba deactivate
$ mamba env remove --name easyfermi

Running

If you defined the variable easyfermi in your shell environment (see Installation), simply type the following in the terminal:

$ easyfermi

Otherwise, type:

$ mamba activate easyfermi
$ python -c "import easyfermi"

Substituting mamba by conda if this is the case for you.
