Limitations

Unity SDK

Headless Mode

If you enable Headless mode, you will not be able to collect visual observations from your agents.

Rendering Speed and Synchronization

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.

Python API

Python version

As of version 0.3, we no longer support Python 2.

Tensorflow support

Currently Ml-Agents uses TensorFlow 1.7.1 due to the version of the TensorFlowSharp plugin we are using.
