If you enable Headless mode, you will not be able to collect visual observations from your agents.
Currently the speed of the game physics can only be increased to 100x real-time. The Academy also moves in time with FixedUpdate() rather than Update(), so game behavior implemented in Update() may be out of sync with the agent decision making. See Execution Order of Event Functions for more information.
As of version 0.3, we no longer support Python 2.
Currently the Ml-Agents toolkit uses TensorFlow 1.7.1 only.
