1.18.61

[1.18.61]

Changed

• Update to MXNet 1.3.1. Removed requirements/requirements.gpu-cu{75,91}.txt as CUDA 7.5 and 9.1 are deprecated.

[1.18.60]

Fixed

• Performance optimization to skip the softmax operation for single model greedy decoding is now only applied if no translation scores are required in the output.

[1.18.59]

Added

• Full training state is now returned from EarlyStoppingTrainer's fit().

Changed

• Training state cleanup will not be performed for training runs that did not converge yet.
• Switched to portalocker for locking files (Windows compatibility).

[1.18.58]

Added

• Added nbest translation, exposed as --nbest-size. Nbest translation means to not only output the most probable translation according to a model, but the top n most probable hypotheses. If --nbest-size > 1 and the option --output-type is not explicitly specified, the output type will be changed to one JSON list of nbest translations per line. --nbest-size can never be larger than --beam-size.

Changed

• Changed sockeye.rerank CLI to be compatible with nbest translation JSON output format.
