Description
It turns out that, just as we release Any23 2.1, development of OpenIE has shifted to yet another repository. e.g. from https://github.com/allenai/openie-standalone -->https://github.com/dair-iitd/OpenIE-standalone
This is actually good news as it shows development of OpenIE is continuing which is great for Any23. We should upgrade to the new version 5.0.
