While it is not strictly necessary, it reduces possible conflicts if one installs python packages that do not need to be avalable systemwide into local, virtual environments. An easy option to setup such virtual environments is the venv module.

python3 -m venv /path/to/new/virtual/environment

This creates a local environment under /path/to/new/virtual/environment, which can be loaded via:

source /path/to/new/virtual/environment/bin/activate

Either within your virtual environment or systemwide, the easiest way to install gwemlightcurve is it to run

pip install git+https://github.com/mcoughlin/gwemlightcurves
pip install healpy
pip install lalsuite
pip install ligo.skymap

This process can take a few minutes and ensured that also all relevant packages will be installed. Furthermore, for this tutorial, you will need

pip install jupyter notebook

and the packages python3-dev, python3-tk, which might not be installed by default on your machine.

Sometimes the automatic installation runs into problems, here is an (incomplete) list of problems:

1.) If you get an error like:

error: invalid command 'bdist_wheel'

Then please run

pip install wheel

2.) If you get the error message: Then please run

21 | #include "Python.h"
             ^~~~~~~~~  ERROR: Failed building wheel for sncosmo

Then you should run

sudo apt-get install python3-dev
