resume_from_model

The resume_from_checkpoint field does not contain any additional parameters. You only need to provide the path to a *.ckpt file to resume training. If resuming training is not required, this field can be omitted or set to null.

When resuming training, changes to configuration options such as max_epoch or gradient clipping will take effect, as they are not recorded in the checkpoint. However, modifications to parameters like the learning rate will have no effect.

Note

If your training process depends on a validation set, keep in mind that the validation metrics may differ before and after resuming. This is expected because we perform an automatic finite small step sanity check before training starts, where only a few batches are used for validation.
