We just released a first batch of Docker images on the official repository.
These images are built via Github Actions and hosted on Github Container Registry (Add some official Docker images by francoishernandez · Pull Request #2530 · OpenNMT/OpenNMT-py · GitHub).
This should facilitate reproducibililty of various experiments and onboarding of new users.
You can refer to the corresponding section of the Readme to get started.
Please note that these images are for experimental purposes and not necessarily optimized for production.
Feedback welcome, as well as contributions, e.g. to extend to more platforms (only tested on standard amd64 setup)!
