Using Unity ML-Agents
Running ML-Agents through the Python API
You can interact with Unity ML-Agents by [1] opening Unity through python (env = UnityEnvironment(side_channels=[])), [2] resetting the environment (env.reset()), [3] stepping the environment forward until a new input from python is required (env.step()), [4] getting the state of the agent (with any sensory information; env.get_steps(behavior_name: str)) and [5] setting the actions for agents (env.set_actions(behavior_name: str, action: ActionTuple)). For more information, please consult the guides below.

Troubleshooting
Although it is in principle quite easy to set up a Unity ML-Agents environment, in practice there can be a few tricky bugs either with Unity failing to start, version incompatibilities, or dependencies. If you're having specific issues with Unity and/or ML-Agents, for now, contact Frank.
Getting rid of too many log messages in the terminal
Depending on your experiments, it can be the case that you'll see that Unity is sending a bit too many messages. To limit the number of log messages, go to Project Settings->Player->Other Settings->Stack Trace and adjust the settings accordingly.
