Train Opus-MT models
This package includes scripts for training NMT models using MarianNMT and OPUS data for OPUS-MT. More details are given in the Makefile but documentation needs to be improved. Also, the targets require a specific environment and right now only work well on the CSC HPC cluster in Finland.
Structure
Essential files for making new models:
Makefile
: top-level makefileMakefile.env
: system-specific environment (now based on CSC machines)Makefile.config
: essential model configurationMakefile.data
: data pre-processing tasksMakefile.doclevel
: experimental document-level modelsMakefile.tasks
: tasks for training specific models and other things (this frequently changes)Makefile.dist
: make packages for distributing models (CSC ObjectStorage based)Makefile.slurm
: submit jobs with SLURM
Run this if you want to train a model, for example for translating English to French:
make SRCLANG=en TRGLANG=fr train
To evaluate the model with the automatically generated test data (from the Tatoeba corpus as a default) run:
make SRCLANG=en TRGLANG=fr eval
For multilingual (more than one language on either side) models run, for example:
make SRCLANG="de en" TRGLANG="fr es pt" train
make SRCLANG="de en" TRGLANG="fr es pt" eval
Note that data pre-processing should run on CPUs and training/testing on GPUs. To speed up things you can process data sets in parallel using the jobs flag of make, for example using 8 threads:
make -j 8 SRCLANG=en TRGLANG=fr data
Upload to Object Storage
