How to switch from OpenNMT-py to EOLE?

Configuration conversion​

One of the main pillars of EOLE is the full revamping of the configuration structure and validation logic. That means OpenNMT-py configuration files are not supported by default. That being said, a conversion tool has been created to facilitate the transition: eole convert onmt_config

There are a few key things to know:

  • what was previous fully "flat" in OpenNMT-py configurations is now mostly nested in nested sections with specific scope such as training, model, transforms_configs;
  • some parameters were renamed, removed, or replaced by other logics, which makes the conversion script not 100% exhaustive;
  • the conversion script will log the remaining "unmapped settings", to facilitate fixing the last issues manually.

Model conversion​

Models trained with OpenNMT-py can technically be converted to be used with EOLE, but there is no automated tool for now. Feel free to get in touch via Issues or Discussions if that is a blocker.
