towhee.trainer.callback.TensorBoardCallBack¶
- class towhee.trainer.callback.TensorBoardCallBack(summary_writer_constructor: Callable, log_dir: Optional[str] = None, comment: str = '')[source]¶
Bases:
Callback
TensorBoardCallBack is intended to record the essential value(e.g. epoch_loss) to tensorboard after each iteration. If tensorboard is available, you can see the tensorboard in localhost:6006.
- Parameters:
summary_writer_constructor (Callable) – Function which construct tensorboard summary writer.
log_dir (str) – Save directory location.
comment (str) – Comment log_dir suffix appended to the default log_dir.
