Description

Print out various bits of information about a language model.

Options

Boolean options accept either true or false as a value, or the default value if neither value is specified.

--check_consistency[=BOOLEAN]
Check model consistency. Default: true.
--end_symbol=STRING
Class label for sentence end. Default: "</s>".
--fst_align[=BOOLEAN]
Write FST data aligned where appropriate. Default: false.
--fst_compat_symbols[=BOOLEAN]
Require symbol tables to match when appropriate. Default: true.
--fst_default_cache_gc[=BOOLEAN]
Enable garbage collection of cache. Default: true.
--fst_default_cache_gc_limit=INT64
Set the cache byte size that triggers garbage collection. Default: 1048576.
--fst_error_fatal[=BOOLEAN]
If true, FST errors are fatal. Otherwise, returned objects are flagged as bad. For example, FSTs are returned with the kError property set to true, and FST weights set so that Member() returns false. Default: true.
--fst_field_separator=STRING
Set the characters used as a separator between printed fields. Default: " ".
--fst_read_mode=STRING
Default file reading mode for mappable files, "read" to use read(2) or "map" to use mmap(2). Default: "read".
--fst_verify_properties[=BOOLEAN]
Verify fst properties queried by TestProperties. Default: false.
--fst_weight_parentheses=STRING
Set the characters enclosing the first weight of a printed composite weight (e.g., pair weight, tuple weight, and derived classes) to ensure proper I/O of nested composite weights. Must have size 0 (none) or 2 (open and close parenthesis). Default: no parentheses.
--fst_weight_separator=CHARACTER
Set the character separator between printed composite weights. Default: comma.
--help[=BOOLEAN]
Show usage information. Default: false.
--helpshort[=BOOLEAN]
Show brief usage information. Default: false.
--ngram_error_fatal[=BOOLEAN]
If true, NGram errors are fatal. Otherwise, returned objects are flagged as bad; i.e., NGramModel::Error() returns true. Default: true.
--save_relabel_ipairs=FILENAME
Save input relabel pairs to file. Default: do not save.
--save_relabel_opairs=FILENAME
Save output relabel pairs to file. Default: do not save.
--start_symbol=STRING
Class label for sentence start. Default: "<s>".
--tmpdir=PATHNAME
Set the temporary directory to use. Default: /tmp.
--v[=INT32]
Set the verbosity level. Default: 0.
