Disable training on one agent

Hello; I'm trying to train a couple of different Agents. For context: I'm playing around with NN for an RPG, where one agent would have a "Tank" brain, another has a "Healer" brain, etc. I've trained the Tank brain to orient on a target and attack it until it is dead. I'd now like to train the "Healer" brain with a different set of observations/rewards. I've set it up so that each Agent has its own brain to train, and I've given them different BehaviorNames.

Here's my problem: now that the Tank brain is trained, I'd like to train the Priest brain to heal the Tank, where the Tank uses its existing training; ie I don't want to retrain the Tank. However; I can't see how to only train only the Healer; when I run mlagents-learn, both are trained.

Is it possible to tell ml-agents "train *this* agent, but not *that* one (use the existing brain set in BehaviorParameters.Model)"? Apologies if this has a painfully obvious answer...

Thanks!

 

Hi @jeffsim,
You can set the Agent's Behavior Type (in the Behavior Parameters) to "Inference Only". More details are here in the docs: https://github.com/Unity-Technologi...Environment-Design-Agents.md#agent-properties

 

Ah, obvious in retrospect . Thank you!
