I’ve been using opennmt via google colab. Normally, if the runtime on the notebook expires it’s easy for me to restart the notebook and continue training models from the last saved checkpoint. However, in one notebook, the model won’t resume training from the last available checkpoint, and it restarts training from the beginning or the first saved checkpoint. Does anyone know why this may happen and how I can prevent it from happening? Happy to provide more details if they’re needed.
