TensorBoard
TensorBoard is a way to visualize your model and various statistics during or after training.
Custom Usage
If you're using a custom training loop (i.e. gradient tape), then you'll need to set everything up manually.
First create a SummaryWriter
train_log_dir = os.path.join(args.checkpoint_dir, "logs", "train")
train_summary_writer = tf.summary.create_file_writer(train_log_dir)
Scalars
Add scalars using tf.summary.scalar:
with train_summary_writer.as_default():
tf.summary.scalar("training_loss", m_loss.numpy(), step=int(ckpt.step))
PyTorch
PyTorch also supports output tensorboard logs.
See https://pytorch.org/docs/stable/tensorboard.html.
There is also lanpa/tensorboardX but I haven't tried it.
