state.epoch             # 1-based, the first epoch is 1
state.seed              # seed to set at each epoch
state.dataloader        # data passed to engine
state.epoch_length      # optional length of an epoch
state.max_epochs        # number of epochs to run
state.batch             # batch passed to `process_function`
state.output            # output of `process_function` after a single iteration
state.metrics           # dictionary with defined metrics if any
state.times             # dictionary with total and per-epoch times fetched on
                        # keys: Events.EPOCH_COMPLETED.name and Events.COMPLETED.name
