SkyLink | Code for efficiently matching sky catalogs using KDTrees

The latest version of SkyLink can be installed as follows:. I strongly recommend doing this in a conda virtual environment.
This package takes advantage of f-strings which were introduced with Python 3.6. In older python versions, an f-string will result in a syntax error. Make sure you have an updated version of setuptools before installing SkyLink. A simple pip install setuptools -U does it for you. For most users, all the dependencies will install automatically. However, some might encounter issues with the networkit package. If you are one of those users, try conda install networkit and if that fails follow the instructions here. networkit requires CMake 3.5 or higher. Make sure you check this by running the command cmake --version in your terminal. In case pip gives you a gcc error while installing psutil in a conda environment, try conda install psutil before installing SkyLink (source).
