Unable to set Graph Model in Balance Ball

[gerardsimons]

I am following the instructions from https://github.com/Unity-Technologies/ml-agents/blob/master/docs/Getting-Started-with-Balance-Ball.md. All is well until I want to incorporate the model into the Unity environment to see it play the game.

When I follow these instructions :

Change the Type of Brain to Internal.
Drag the <env_name>.bytes file from the Project window of the Editor to the Graph Model placeholder in the 3DBallBrain inspector window.

I get stuck at setting the Graph Model. I simply do not see such a property in the Inspector. This is on MacOS Sierra running Unity 2017.1.1f1

What am I missing here?

Can you expand the console, and see what errors are going on in there with a screenshot? Might be a conflict regarding the Brain or adjacent scripts.

Hi @gerardsimons,

If you just enabled TensorFlow support (see https://github.com/Unity-Technologies/ml-agents/blob/master/docs/Getting-Started-with-Balance-Ball.md#setting-up-tensorflowsharp-support), you might need to restart the Editor.

@eagleEggs Here you go. Hope that helps. Thanks again.

@awjuliani : I already did that at the time, and again now. Does not help unfortunately, thanks for trying though

@gerardsimons I think a quick fix should be to delete the brain component from the game object and add a new Brain component with the same brain parameters. Let me know if that helps.

@vincentpierre That works, should have tried that right of the bat obviously. Thanks for the quick help guys!

Perhaps I cheered too soon. I can indeed get the parameters to show in the inspector now, and I then try to set them to the values I saw previously (although some I did not see of course), but when I press play I do not see it play the game. Maybe I did not set some parameters properly? See screenshot below:

@awjuliani : Can you help me out with this or should I raise a new issue? I have ensured the model is only exported to bytes once the reward threshold has been reached.

Can you tell me if you get an error in the console ?
It seems the pause button is pressed (right next to the play button) have you tried clicking on it ?

[gerardsimons]

Sorry forgot about this, but yeah it seems sometimes you have to start it a few times before it actually starts.
