The issue im facing right now is the getbestmodel method
Im not able to figure out how to do that second call to get the weights from client since aggreggate_fir gets called only once per global epoch
Any help is appreciated :smile:

Hi @wehtam , thanks for your question.
I think you actually don’t need to have the GETBESTMODEL call to receive the model params from the specific client.
As you already have the gid which is essentially the client_id, and you can get the model for that client by its id at the server side. Does it make sense?

oh okay I am new to flower so where can i read about how that works or any similar code examples?

Here is a link that helps with the custom strategy: Use strategies - Flower Framework

Once you have a custom strategy, then you can access the model of each clients at the server side.
