Computes the times for high-level operations in the training loops.
Details
Records are saved in ctx$records$profile. Times are stored as seconds.
Data is stored in the following structure:
fit time for the entire fit procedure.
epoch times per epoch
(train/valid)_batch time per batch of data processed, including data acquisition and step.
(train/valid)_step time per step (training or validation step) - only the model step. (not including data acquisition and preprocessing)
Note
In general you don't need to use these callback by yourself because it's always
included by default in fit.luz_module_generator().
