Parameters
----------
epochs : int, optional
data_size : int, optional
Number of training pairs.
batch_size : int, optional
Number of training pairs per batch.
verbose : int
0: epoch, 1: batch (transient), 2: batch. [default: 1].
Will be set to `0` unless both `data_size` and `batch_size`
are given.
tqdm_class : optional
`tqdm` class to use for bars [default: `tqdm.auto.tqdm`].
tqdm_kwargs : optional
Any other arguments used for all bars.
