There is a platform called Arena built on top of the Unity game engine and there is Unity mlagents. Do they have a relation between them or are they completely different products ? I saw that Arena has also the pyramid example scene in it and thought maybe Arena was the previous version of mlagents however it is keeped updated in Github so I am confused.
Arena was built on top of v0.8.2 of mlagents-envs i.e. a very old version of ML-Agents that is not compatible with the current release. Arena is not the same as ML-Agents but a project that uses our (albeit an older version) environment API.
