Japanese GPT2 Lyric Model

Model description

The model is used to generate Japanese lyrics.

You can try it on my website https://lyric.fab.moe/

How to use

import torch
from transformers import T5Tokenizer, GPT2LMHeadModel

tokenizer = T5Tokenizer.from_pretrained("skytnt/gpt2-japanese-lyric-small")
model = GPT2LMHeadModel.from_pretrained("skytnt/gpt2-japanese-lyric-small")


def gen_lyric(prompt_text: str):
    prompt_text = "<s>" + prompt_text.replace("\n", "\\n ")
    prompt_tokens = tokenizer.tokenize(prompt_text)
    prompt_token_ids = tokenizer.convert_tokens_to_ids(prompt_tokens)
    prompt_tensor = torch.LongTensor(prompt_token_ids).to(device)
    prompt_tensor = prompt_tensor.view(1, -1)
    # model forward
    output_sequences = model.generate(
        input_ids=prompt_tensor,
        max_length=512,
        top_p=0.95,
        top_k=40,
        temperature=1.0,
        do_sample=True,
        early_stopping=True,
        bos_token_id=tokenizer.bos_token_id,
        eos_token_id=tokenizer.eos_token_id,
        pad_token_id=tokenizer.pad_token_id,
        num_return_sequences=1
    )

    # convert model outputs to readable sentence
    generated_sequence = output_sequences.tolist()[0]
    generated_tokens = tokenizer.convert_ids_to_tokens(generated_sequence)
    generated_text = tokenizer.convert_tokens_to_string(generated_tokens)
    generated_text = "\n".join([s.strip() for s in generated_text.split('\\n')]).replace(' ', '\u3000').replace('<s>', '').replace('</s>', '\n\n---end---')
    return generated_text


print(gen_lyric("桜が咲く"))

Inference Examples
This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social visibility and check back later, or deploy to Inference Endpoints (dedicated) instead.
