callback_remote_monitor {keras3}

Callback used to stream events to a server.

Description

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 named list of event data. If send_as_json = TRUE, the content type of the request will be "application/json". Otherwise the serialized JSON will be sent within a form.

Usage

callback_remote_monitor(
  root = "http://localhost:9000",
  path = "/publish/epoch/end/",
  field = "data",
  headers = NULL,
  send_as_json = FALSE
)

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. when send_as_json = FALSE).

headers

Named list; optional custom HTTP headers.

send_as_json

Boolean; whether the request should be sent as "application/json".

Value

A Callback instance that can be passed to fit.keras.src.models.model.Model().
