japanese-gpt2-small
This repository provides a small-sized Japanese GPT-2 model. The model is provided by rinna.
How to use the model
NOTE: Use T5Tokenizer to initiate the tokenizer.
from transformers import T5Tokenizer, GPT2LMHeadModel
tokenizer = T5Tokenizer.from_pretrained("rinna/japanese-gpt2-small")
tokenizer.do_lower_case = True # due to some bug of tokenizer config loading
model = GPT2LMHeadModel.from_pretrained("rinna/japanese-gpt2-small")
Model architecture
A 12-layer, 768-hidden-size transformer-based language model.
Training
The model was trained on Japanese CC-100 and Japanese Wikipedia to optimize a traditional language modelling objective on 8\*V100 GPUs for around 15 days. It reaches around 21 perplexity on a chosen validation set from CC-100.
Tokenization
The model uses a sentencepiece-based tokenizer, the vocabulary was trained on the Japanese Wikipedia using the official sentencepiece training script.
