tf.compat.v1.keras.callbacks.RemoteMonitor, `tf.compat.v2.keras.callbacks.RemoteMonitor`

tf.keras.callbacks.RemoteMonitor(
    root='http://localhost:9000', path='/publish/epoch/end/', field='data',
    headers=None, send_as_json=False
)

Requires the requests library. Events are sent to root + '/publish/epoch/end/' by default. Calls are HTTP POST, with a data argument which is a JSON-encoded dictionary of event data. If send_as_json is set to True, the content type of the request will be application/json. Otherwise the serialized JSON will be sent within a form.

Arguments
root	String; root url of the target server.
path	String; path relative to root to which the events will be sent.
field	String; JSON field under which the data will be stored. The field is used only if the payload is sent within a form (i.e. send_as_json is set to False).
headers	Dictionary; optional custom HTTP headers.
send_as_json	Boolean; whether the request should be sent as application/json.

Methods

on_batch_begin

on_batch_begin(
    batch, logs=None
)

A backwards compatibility alias for on_train_batch_begin.

on_batch_end

View source

on_batch_end(
    batch, logs=None
)

A backwards compatibility alias for on_train_batch_end.

on_epoch_begin

View source

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

View source

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

View source

on_predict_batch_begin(
    batch, logs=None
