説明

🚀 Feature

There can be use-cases when we would like to get trainer's epoch/iteration or/and other items from trainer.state. Let's propose an API such that we could get easily trainer's state from evaluator.

前提条件: PyTorch Ignite basicsUnderstanding of trainer and evaluator
初心者向け度: 50
調査方針: Investigate the trainer.state object in ignite/engine/engine.py and the evaluator's process function. Review the discussion at https://discuss.pytorch.org/t/get current epoch inside process function of evaluator/162926 to understand the use case. Propose an API design that allows evaluators to access trainer state, ensuring backward compatibility.
