Install

pip install jptranstokenizer

Quickstart

This is the example to use jptranstokenizer.JapaneseTransformerTokenizer with sentencepiece model of nlp-waseda/roberta-base-japanese and Juman++.
Before the following steps, you need to install pyknp and Juman++.

>>> from jptranstokenizer import JapaneseTransformerTokenizer
>>> tokenizer = JapaneseTransformerTokenizer.from_pretrained("nlp-waseda/roberta-base-japanese")
>>> tokens = tokenizer.tokenize("外国人参政権")
# tokens: ['▁外国', '▁人', '▁参政', '▁権']

Note that different dependencies are required depending on the type of tokenizer you use.
