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")
A 6-layer, 512-hidden-size transformer-based language model.
The model was trained on Japanese CC-100 and Japanese Wikipedia to optimize a traditional language modelling objective on 8\*V100 GPUs for around 4 days. It reaches around 28 perplexity on a chosen validation set from CC-100.
The model uses a sentencepiece-based tokenizer, the vocabulary was trained on the Japanese Wikipedia using the official sentencepiece training script.
