I tried the following command:

perl /home/Moses/mosesdecoder/scripts/generic/binarize4moses2.perl
--phrase-table=/home/vito/phrase-table.sorted
--lex-ro=/home/vito/reordering-table.sorted
--output-dir=/home/vito/integrated_phrase-reordering/ --num-lex-scores=6

but it gets stuck with the following message:

Reading phrase table finished, writing remaining files to disk.
terminate called after throwing an instance of 'util::ProbingSizeException'
what(): ./util/probing_hash_table.hh:150 in
util::ProbingHashTable<EntryT, HashT, EqualT, ModT>::Entry*
util::ProbingHashTable<EntryT, HashT, EqualT, ModT>::Insert(const T&) [with
T = Moses2::Entry; EntryT = Moses2::Entry; HashT = boost::hash<long
unsigned int>; EqualT = std::equal_to<long unsigned int>; ModT =
util::DivMod; util::ProbingHashTable<EntryT, HashT, EqualT,
ModT>::MutableIterator = Moses2::Entry*; util::ProbingHashTable<EntryT,
HashT, EqualT, ModT>::Entry = Moses2::Entry] threw ProbingSizeException
because `++entries_ >= buckets_'.
Hash table with 1 buckets is full.
