adrianeboyd f7471abd82 Add pkuseg and serialization support for Chinese (#5308) ... * Add pkuseg and serialization support for Chinese Add support for pkuseg alongside jieba * Specify model through `Language` meta: * split on characters (if no word segmentation packages are installed) ``` Chinese(meta={"tokenizer": {"config": {"use_jieba": False, "use_pkuseg": False}}}) ``` * jieba (remains the default tokenizer if installed) ``` Chinese() Chinese(meta={"tokenizer": {"config": {"use_jieba": True}}}) # explicit ``` * pkuseg ``` Chinese(meta={"tokenizer": {"config": {"pkuseg_model": "default", "use_jieba": False, "use_pkuseg": True}}}) ``` * The new tokenizer setting `require_pkuseg` is used to override `use_jieba` default, which is intended for models that provide a pkuseg model: ``` nlp_pkuseg = Chinese(meta={"tokenizer": {"config": {"pkuseg_model": "default", "require_pkuseg": True}}}) nlp = Chinese() # has `use_jieba` as `True` by default nlp.from_bytes(nlp_pkuseg.to_bytes()) # `require_pkuseg` overrides `use_jieba` when calling the tokenizer ``` Add support for serialization of tokenizer settings and pkuseg model, if loaded * Add sorting for `Language.to_bytes()` serialization of `Language.meta` so that the (emptied, but still present) tokenizer metadata is in a consistent position in the serialized data Extend tests to cover all three tokenizer configurations and serialization * Fix from_disk and tests without jieba or pkuseg * Load cfg first and only show error if `use_pkuseg` * Fix blank/default initialization in serialization tests * Explicitly initialize jieba's cache on init * Add serialization for pkuseg pre/postprocessors * Reformat pkuseg install message		2020-04-18 17:01:53 +02:00
