Inherits From: Callback
tf.keras.callbacks.TerminateOnNaN()
Methods
on_batch_begin
on_batch_begin(
    batch, logs=None
)
A backwards compatibility alias for on_train_batch_begin.
on_batch_end
on_batch_end(
    batch, logs=None
)
A backwards compatibility alias for on_train_batch_end.
on_epoch_begin
on_epoch_begin(
    epoch, logs=None
)
Called at the start of an epoch.
Subclasses should override for any actions to run. This function should only be called during TRAIN mode.
| Arguments | |
|---|---|
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
on_epoch_end(
    epoch, logs=None
)
Called at the end of an epoch.
Subclasses should override for any actions to run. This function should only be called during TRAIN mode.
| Arguments | |
|---|---|
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
on_predict_batch_begin(
    batch, logs=None
