Sockeye

Sockeye is an open-source sequence-to-sequence framework for Neural Machine Translation built on PyTorch. It implements distributed training and optimized inference for state-of-the-art models, powering Amazon Translate and other MT applications.

Recent developments and changes are tracked in our CHANGELOG.

For a quickstart guide to training a standard NMT model on any size of data, see the WMT 2014 English-German tutorial.

If you are interested in collaborating or have any questions, please submit a pull request or issue. You can also send questions to sockeye-dev-at-amazon-dot-com. Developers may be interested in our developer guidelines.
