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"). |
add
add( n, values=None )
update
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 . |
