@emilyzfliu - this looks like its coming along. some comments on reorganizing a few pieces.

if you look at this figure: https://www.researchgate.net/figure/Sequence-diagram-of-an-asynchronous-client-server-request_fig4_228371987 it's called a sequence diagram. and is useful to draw something like this to figure out what the client needs to do interact with the server.

an example client

while (True):
    if check for new model:
        client: get most recent model
        client: train model
        client: post model to server 
    else:
         if new data available:
            client: train model
            client: post model to server 
         sleep for sometime
