Organize logged charts and media into related groups by naming logged items with a shared prefix, which makes it easier to scan and compare metrics in the W&B UI. The / character separates logged panels in the W&B UI. By default, the segment of the logged item’s name before the / defines a group of panels known as a Panel Section. For example, the following code logs metrics into two panel sections, val and train:
import wandb

with wandb.init() as run:

   run.log({"val/loss": 1.1, "val/acc": 0.3})
   run.log({"train/loss": 0.1, "train/acc": 0.94})
To change how W&B groups panels, use the Workspace settings to group panels based on either the first segment or all segments separated by /.
