nagisa_bert

A BERT model for nagisa. The model is available in Transformers 🤗.

A tokenizer for nagisa_bert is available here.

Install

To use this model, the following python library must be installed. You can install nagisa_bert by using the pip command.

Python 3.7+ on Linux or macOS is required.

$ pip install nagisa_bert

Usage

This model is available in Transformer's pipeline method.

>>> from transformers import pipeline
>>> from nagisa_bert import NagisaBertTokenizer

>>> text = "nagisaで[MASK]できるモデルです"
>>> tokenizer = NagisaBertTokenizer.from_pretrained("taishi-i/nagisa_bert")
>>> fill_mask = pipeline("fill-mask", model='taishi-i/nagisa_bert', tokenizer=tokenizer)
>>> print(fill_mask(text))

Tokenization and vectorization.

>>> from transformers import BertModel
>>> from nagisa_bert import NagisaBertTokenizer

>>> text = "nagisaで[MASK]できるモデルです"
>>> tokenizer = NagisaBertTokenizer.from_pretrained("taishi-i/nagisa_bert")
>>> tokens = tokenizer.tokenize(text)
>>> print(tokens)
['na', '##g', '##is', '##a', 'で', '[MASK]', 'できる', 'モデル', 'です']

>>> model = BertModel.from_pretrained("taishi-i/nagisa_bert")
>>> h = model(**tokenizer(text, return_tensors="pt")).last_hidden_state
>>> print(h)
