# Change the following values to preprocess a new dataset.
# TRAIN_DIR, VAL_DIR and TEST_DIR should be paths to
# directories containing sub-directories with .java files
# each of {TRAIN_DIR, VAL_DIR and TEST_DIR} should have sub-dirs,
# and data will be extracted from .java files found in those sub-dirs).
# DATASET_NAME is just a name for the currently extracted
# dataset.
# MAX_CONTEXTS is the number of contexts to keep for each
# method (by default 200).
# WORD_VOCAB_SIZE, PATH_VOCAB_SIZE, TARGET_VOCAB_SIZE -
# - the number of words, paths and target words to keep
# in the vocabulary (the top occurring words and paths will be kept).
# The default values are reasonable for a Tesla K80 GPU
# and newer (12 GB of board memory).
# NUM_THREADS - the number of parallel threads to use. It is
# recommended to use a multi-core machine for the preprocessing
# step and set this value to the number of cores.
# PYTHON - python3 interpreter alias.
