Hey Guys,
I know this is a pretty noob question. But how do i set up Unity ML agents with Python .
Here are the steps i followed .
1.) Created Unity Project and imported all C# scripts from ML-agents folder
2.) Created Academy and Brain object and added scripts accordingly.
3.) Created agent script as follows
public override void AgentStep(float[] actions)
{
if(brain.brainParameters.actionSpaceType == StateType.continuous )
{
driverHelper.Accelarate = actions [0];
driverHelper.Steering = actions [1];
driverHelper.Brake = actions[2];
for (int i = 0; i < sensorHolder.sensors.Count; ++i)
if (sensorHolder.sensors *.ReturnedDistance <= 2f) {*
-
done = true;* -
reward = -1f;* -
} else {*
if (done == false)
-
reward = 0.1f;* -
}* -
}* -
}*
-
public override List CollectState()*
-
{*
-
List<float> State = new List<float> ();* -
for(int i=0; i < sensorHolder.sensors.Count;++i)*
_ State.Add (sensorHolder.sensors*.ReturnedDistance);*_
* return State;*
* }*
Everything works finely till now. even tested out with player mode in Brain Script
But How can i connect this with my python ML code
When ever i try to execute the following command from the ml-agents directory
python python/learn.py “testcar” --train
I get the following errors
unityagents.exception.UnityEnvironmentException: Couldn’t launch the testcar environment. Provided filename does not match any environments.
And in Game error

Could anyone be kind enough to tell me how i can fix this and any pointers on How to send signals via python to Unity is appreciated.
Thanks
Regards
P.P.S. Sorry for my eng.
