The Unity Machine Learning Agents Toolkit (ML-Agents) is an open-source Unity3D plugin that enables games and simulations to serve as environments for training intelligent agents. Agents - usually implemented as scripted C# Unity components - can be trained using reinforcement learning, imitation learning, neuroevolution, or other machine learning methods through a Python API.

How to build a Multiagent RL model with MLAgents toolkit in Unity3D?
I am building a multiagent RL model with MLAgents toolkit in Unity3D.
The idea is, the model will have 2 agents(spheres) and 1 target(cube) on a platform(floor). Both agent need to reach the target before each other, if an agent will reach the goal…

Unity ML Agents - My Trained Agent is not moving towards all Checkpoints. Instead stuck in between
I am creating a bike racing game in which I want a AI to race as a opponent with me. So I decided and created a model by training the agent for Left turns, right turns, both left and right turns in a simple track.
The model was trained very good…

Can agents in Unity ML-agents collect observations asynchronously?
The vision sensor I use for each agent is quite processing intensive, so I figured it would improve the frame rate if the agents didn't all collect their observations on the same environment step, but I haven't found a way to accomplish this. Is it…
