Quickstart example runs for a long time about opennmt-tf HOT 5 OPEN

By default, the training will run for 500,000 steps.

For the quickstart this value is indeed way too high and we don't expect users to run the full training (we should probably add a note!). The quickstart is mostly meant to showcase a minimal configuration and the main command lines.

When training on real data, this default value is more reasonable and the training could indeed take days. However, there are options to automatically stop the training earlier, but they are not enabled by default.

Thanks for a quick reply. Yes, I think a notice about expectations would be helpful. Usually, toy examples are very quick to run and evaluate. Perhaps also with some expectations about the output, so you know what you should be getting if OpenNMT runs correctly.

Presumably, one can abort training at any time and just evaluate any of the saved checkpoints?

Yes.

Just to show you what I mean with expected output, what I am getting from 70k steps of training is so garbled that I am worried that something with the software installation has gone wrong. Perhaps ballparking BLEU results is an option?

The dataset used in the quickstart is too small to get anything useful from a Transformer training. We would need to use a bigger training set in order to define an expected BLEU score.
