Recipes

Recipes for training OpenNMT systems

You will find here some "recipes" which basically script the end-to-end data preparation, preprocessing, training and evaluation.

Requirements

• You do need OpenNMT - see here. If you clone Recipes.git repo at the same level as OpenNMT.git on your local computer, you don't need to update the PATH in the scripts. Otherwise update the line OPENNMT_PATH=../../OpenNMT
• for evaluation scripts, you do need perl XML::Twig module (perl -MCPAN -e 'install XML::Twig)
