The format of the data files is defined by the
opennmt.inputters.Inputter used by your model.
opennmt.inputters.TextInputters expect a text file as input where:
- sentences are separated by a newline
- tokens are separated by a space (unless a custom tokenizer is set, see Tokenization)

opennmt.inputters.SequenceRecordInputter expects a file with serialized TFRecords. To simplify the preparation of these data, the script
bin/ark_to_records.py can be used to convert vectors serialized in the ARK text format:
KEY [ FEAT1.1 FEAT1.2 FEAT1.3 ... FEAT1.n ... FEATm.1 FEATm.2 FEATm.3 ... FEATm.n ]
which describes an example of
m vectors of depth
n and identified by
python -m bin.ark_to_records -h for the script usage. It also accepts an optional indexed text file (i.e. with lines prefixed with
KEYs) to generate aligned source vectors and target texts.
opennmt.inputters.ParallelInputter, as many input files as inputters are expected. You have to configure your YAML file accordingly:
data: train_features_file: - train_source_1.records - train_source_2.txt - train_source_3.txt
