udkanbun.load() has only one option udkanbun.load(MeCab=False). By default, the UD-Kanbun pipeline uses MeCab for tokenizer and POS-tagger, then uses UDPipe for dependency-parser. With the option MeCab=False the pipeline uses UDPipe for all through the processing.

Installation

Binary wheel is available for Linux, and is installed by default when you use pip:

pip install udkanbun
