Error: There are option(s) in a config file that are not expected

[Supachan]

I got the weird problem. Before it happened, I ran the command /.run-me.sh with -w 1024 (by default: -w 3000. Of course, it would take very long time to finish translation between English-Romanian with marian-examples.

I decided to stop running, added --max-length 30, and ran the command again.
The error is:

How can I fix it? Please let me know.

Thanks in advance.

Please follow this advice: marian-nmt/marian#271 or just remove model.npz.yml.
