To test translation, execute
THEANO_FLAGS=mode=FAST_RUN,floatX=float32,device=cpu python test_translate.py
To test scoring, execute
THEANO_FLAGS=mode=FAST_RUN,floatX=float32,device=cpu python test_score.py
more sample models (including scripts for pre- and postprocessing) are provided at: http://statmt.org/rsennrich/wmt16_systems/
to test training, execute
THEANO_FLAGS=mode=FAST_RUN,floatX=float32,device=cpu ./test_train.sh
note that the training script is just a toy setup to make sure the scripts run, and to allow for speed comparisons. For instructions to train a real-scale system, check the instructions at https://github.com/rsennrich/wmt16-scripts
