Thanks for the great comment, Esmaeil! I do agree with you that the GitHub repo is not maintained or owned directly by Facebook but rather by Oskar Triebe, the first author of the AR-Net paper.

However, Facebook AI does introduce the library as their own effort on Twitter: https://twitter.com/facebookai/status/1333474249177243648?lang=en

Still I do agree with you that Facebook AI does not officially maintain the library on GitHub even though it played an important role in creating it. Thanks for pointing that out!
