Hi,

I am wanting to make a system that has a trainer (PPO) fully set up locally on a server, then the client would send requests for predictions from an environment. The server would then create an actor (or process?) that creates a new ID for the session and essentially `trains` on the incoming requests.

The idea here is to create a game and have clients make HTTP requests for predictions (the latency does not affect the gameplay). I am aware of Unity ML agents, but the clients may be connected/disconnected at will and from environments that don’t have python installed for example.

Is this possible? If so, can anyone point me in the right direction?

Thanks!

Edit:  
In particular, there is the policy\_client + policy\_server. Can I have a request be sent to the policy\_client whenever I need a new game (from a client) which would use the `new` method to startup a new game that is running parallel to the other games? policy\_client then forwards all the requests as normal to police\_server.

So instead of policy\_client running the game, it is getting requests with all the information from different devices, and acting as a mediary for policy\_server

Hi @Denys_Ashikhin ,

Have a look at `ExternalEnv` and `PolicyClient`.  
I can’t point you into the right direction though, you’ll have to code this up yourself.  
You can modify PolicyClient to your liking.
