class ashpy.callbacks.counter_callback.CounterCallback(event, fn, name, event_freq=1)

Bases: ashpy.callbacks.callback.Callback

Count events of a specific type. Calls fn passing the context every event_freq.

Useful for logging or for measuring performance. If you want to implement a callback defining a certain behaviour every n_events you can just inherit from CounterCallback.

Methods

__init__(event, fn, name[, event_freq])	Initialize the CounterCallback.
on_event(event, context)	Count events and calls fn.

Attributes

name	Return the name of the callback.
name_scope	Returns a tf.name_scope instance for this class.
submodules	Sequence of all sub-modules.
trainable_variables	Sequence of variables owned by this module and it’s submodules.
variables	Sequence of variables owned by this module and it’s submodules.

__init__(event, fn, name, event_freq=1)

Initialize the CounterCallback.

Parameters:

• event (ashpy.events.Event) – event to count.
• fn (Callable) – function to call every event_freq events.
• event_freq (int) – event frequency.
• name (str) – name of the Callback.

Raises:

ValueError – if event_freq is not valid.

Return type:

None

on_event(event, context)

Count events and calls fn.

Parameters:

• event (ashpy.callbacks.events.Event) – current event.
• context (ashpy.contexts.context.Context) – current context.
