Summary of Changes
Hello @chenyushuo, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request primarily refactors the Trainer.train function to be asynchronous, enabling more efficient and non-blocking operations within the training loop. This change propagates through the system, making various data sampling and reading components asynchronous as well. Additionally, it includes a bug fix by adjusting the lifetime management of the Synchronizer actor, ensuring proper resource handling in different operational modes.
Highlights
- Asynchronous Trainer Refactor: The core
Trainer.trainmethod has been refactored to anasyncfunction, enabling more efficient and non-blocking operations within the training loop. This change allows for concurrent execution of training steps and synchronization checks. - Asynchronous Data Handling: The
SampleStrategyimplementations andBufferReaderinterfaces now support asynchronous data reading (read_async). This new asynchronous capability is utilized by both theTrainerandExplorercomponents for improved data pipeline efficiency. - Synchronizer Lifetime Management: The
Synchronizeractor's lifetime is now conditionally set todetachedbased on the configuration mode (explore or specific train algorithms). This modification addresses a bug related to the synchronizer's lifecycle and ensures proper resource handling in different operational scenarios. - Enhanced Synchronization Logic: Updates to the
SynchronizerandTrainer'ssync_weightlogic, including newlast_sync_steptracking inTrainer, ensure more robust and timely model weight synchronization across distributed components. - Explorer Async Adaptations: The
Explorercomponent has been updated toawaitpreviously synchronousevaland datareadoperations, aligning its behavior with the new asynchronous patterns introduced in theTrainerand data readers.

Code Review
This pull request refactors the Trainer.train function to be asynchronous, improving weight synchronization. I've identified areas for improvement in handling blocking I/O operations within async methods in buffer readers and suggested enhancing the readability of a complex condition in the synchronizer.
