"""
Simple loop which sets up a remote connection. The paired agent can run this same loop
but with the '--remote-host' flag set. For example...

Agent 1:
python remote.py

Agent 2:
python remote.py --remote-host

Now humans connected to each agent can communicate over that thread.


If you want to use this to feed a dataset to a remote agent, set the '--task':

Agent 1:
python remote.py -t "babi:task1k:1"


If you would like to use a model instead, merely set the '--model' flag:

Either Agent:
python remote.py -m seq2seq
