Yep, if communication is both ways, there is no way (that I can think of) it can be solved for offline mode.

But if the calls that are made from the server to the client can be redundant in a specific setup (some functionality will not work, but enough valuable functionality remains) then it is possible in the manual way

Hi WackyRabbit7 ,
Yes we had the same experience with kaggle competitions. We ended up having a flag that skipped the task init :(
Introducing offline mode is on the to do list, but to be honest it is there for a while. The thing is, since the Task object actually interacts with the backend, creating an offline mode means simulation of the backend response. I'm open to hacking suggestions though :)

I assume that at some points in the execution, the client (where the task is running) is sending JSONs to the mongo service, and that is what we see in the web UI.
Since we are talking about a case where there is no internet available, maybe these could be dumped into files/stdout and let the user manually insert them.
The manual insertion UX could be something like a CLI copy-paste or and endpoint for files - but since your UX is so good ( 🙂 ) I'm sure you'll figure this part out better

Hi WackyRabbit7 ,
Your description is essentially true, however I'll just clarify that Trains uses a REST protocol, and that the calls are bidirectional. What AgitatedDove14 was referring to is that Trains replies on the responses, and doesn't only send data. This is the reason an "offline" mode is required - not only to store the data that can be later sent to the server, but also to emulate the server's response in order to allow Trains to continue operating as expected.
