I feel I’ve discussed this with someone somewhere (perhaps a gitissue…can’t find it!) but I can’t find it and now I came back and can’t figure out why my wandb command looks the way it does:

```auto
        # - log to wandb
        if log_to_wandb:
            if it == 0:
                wandb.define_metric("train loss", step_metric=it_or_epoch)
                wandb.define_metric("train acc", step_metric=it_or_epoch)
                wandb.define_metric("val loss", step_metric=it_or_epoch)
                wandb.define_metric("val val", step_metric=it_or_epoch)
                # if mdl_watch_log_freq == -1:
                # wandb.watch(args.base_model, args.criterion, log="all", log_freq=mdl_watch_log_freq)
            # - log to wandb
            wandb.log(data={it_or_epoch: it, # custom step,
                            'train loss': train_loss,
                            'train acc': train_acc,
                            'val loss': val_loss,
                            'val acc': val_acc},
                            commit=True)
            # if it == total_its: # not needed here, only needed for normal SL training
            # wandb.finish()

```

can someone help me decipher what this was supposed to mean? Especially the commit option?

Hi Brando,  
It looks like it is logging steps to our UI. To know more about commit = True, look at this doc [https://docs.wandb.ai/guides/track/log#stepwise-and-incremental-logging](https://docs.wandb.ai/guides/track/log#stepwise-and-incremental-logging)

Warmly,  
Leslie
