About reference server

[liunian-Jay]

Thank you for your excellent work.
Some questions bother me, in ref_server.py

raw_queue = queue.LifoQueue()
result_queue = queue.LifoQueue()

why use a stack? Wouldn't this result in old sampled data being used for training later?

[lsdefine]

feel free to use Queue or Stack use stack if the generator is faster than the trainer, the trainer will use the latest data, and the old data will be never used (because of the fast generator) Jay ***@***.***> 于2025年6月6日周五 16:17写道：
