tf.compat.v1.keras.callbacks.CallbackList

tf.keras.callbacks.CallbackList(
    callbacks=None, add_history=False, add_progbar=False, model=None, **params
)

Args
callbacks	List of Callback instances.
add_history	Whether a History callback should be added, if one does not already exist in the callbacks list.
add_progbar	Whether a ProgbarLogger callback should be added, if one does not already exist in the callbacks list.
model	The Model these callbacks are used with.
**params	If provided, parameters will be passed to each Callback via Callback.set_params.

on_epoch_begin

View source

on_epoch_begin(
    epoch, logs=None
)

Calls the on_epoch_begin methods of its callbacks.

This function should only be called during TRAIN mode.

Args
epoch	Integer, index of epoch.
logs	Dict. Currently no data is passed to this argument for this method but that may change in the future.

on_epoch_end

View source

on_epoch_end(
    epoch, logs=None
)

Calls the on_epoch_end methods of its callbacks.

This function should only be called during TRAIN mode.

Args
epoch	Integer, index of epoch.
logs	Dict, metric results for this training epoch, and for the validation epoch if validation is performed. Validation result keys are prefixed with val_.

on_predict_batch_begin

View source

on_predict_batch_begin(
    batch, logs=None
)

Calls the on_predict_batch_begin methods of its callbacks.

Args
batch	Integer, index of batch within the current epoch.
logs	Dict, contains the return value of model.predict_step, it typically returns a dict with a key 'outputs' containing the model's outputs.

on_predict_batch_end

View source

on_predict_batch_end(
    batch, logs=None
)

Calls the on_predict_batch_end methods of its callbacks.

Args
batch	Integer, index of batch within the current epoch.
logs	Dict. Aggregated metric results up until this batch.

on_predict_begin

View source

on_predict_begin(
    logs=None
