How to log a numerical series?
from neptune_scale import Run

run = Run()

for step in epoch:
    # your training loop
    run.log_metrics(
        data={"loss": 0.14},
        step=step,
    )

To log several metrics at once, pass multiple key-value pairs:

run.log_metrics(
    data={"loss": 0.14, "acc": 0.78},
    step=step,
)

Changing chart settings​

The Charts tab displays a separate chart for each metric that's logged to the currently visualized runs.

Comparing grouped runs​

Exporting charts​

You can export the displayed charts to a new or existing dashboard or report:

  • Dashboard saves the set of charts as a template that you can apply to any visible runs.
  • Report saves the set of charts, including which runs are visible.

The result snapshots the attribute names that match the search query at the time of exporting the charts. If new metrics appear that also match this query, a dashboard or report doesn't update to include them. For charts to update dynamically, you must update the widget settings. For details, see Select metrics dynamically.
