Defined in tensorflow/python/keras/utils/generic_utils.py.

Displays a progress bar.

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).

__init__

__init__(
    target,
    width=30,
    verbose=1,
    interval=0.05,
    stateful_metrics=None
)

Methods

add

add(
    n,
    values=None
)

update

update(
    current,
    values=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.
