How to communicate with other PCs for Federated Learning

Hi guys,

I am trying to implement federated learning using my own dataset. I put the dataset on three different computers, and I want to read them and feed them to TensorFlow Federated. I’ve read the tutorials about TFF, but I couldn’t find a way to communicate with the other PCs. Where should I add the IP address, or generally, is there any way to communicate with other PCs?
Thank you
