mlr_callback_set.tb: TensorBoard Logging Callback

In mlr3torch: Deep Learning with 'mlr3'

TensorBoard Logging Callback

Description

Logs training loss, training measures, and validation measures as events. To view them, use TensorBoard with tensorflow::tensorboard() (requires tensorflow) or the CLI.

Details

Logs events at most every epoch.

Method new()

Creates a new instance of this R6 class.

Usage

CallbackSetTB$new(path, log_train_loss)

Arguments
