Displays a progress bar.

tf.keras.utils.Progbar(
    target, width=30, verbose=1, interval=0.05, stateful_metrics=None,
    unit_name='step'
)

Arguments:

  • target: Total number of steps expected, None if unknown.
  • width: Progress bar width on screen.
  • verbose: Verbosity mode, 0 (silent), 1 (verbose), 2 (semi-verbose)
  • stateful_metrics: Iterable of string names of metrics that should not be averaged over time. Metrics in this list will be displayed as-is. All others will be averaged by the progbar before display.
  • interval: Minimum visual progress update interval (in seconds).
  • unit_name: Display name for step counts (usually "step" or "sample").

update(
    current, values=None, finalize=None
)

Updates the progress bar.

Arguments:

  • current: Index of current step.
  • values: List of tuples: (name, value_for_last_step). If name is in stateful_metrics, value_for_last_step will be displayed as-is. Else, an average of the metric over time will be displayed.
  • finalize: Whether this is the last update for the progress bar. If None, defaults to current >= self.target.
