[Feature Request] rinna's Japanese GPT model support

[katsu560]

Thanks @ggerganov for your sharing.

I want to use GPT on my local pc.
rinna Co.,Ltd is Japanese AI company. rinna provides some GPT models on huggingface.

I'd like to use these models with ggml gpt.
But, I can't convert these models for ggml.
I think these models are pytorch bin model and tensorflow H5 weight.

Could you convert and support these models ?

You can use examples/gpt-2/convert-h5-to-ggml.py to convert these models:

Thank you for your comment, ocordeiro.
I sync-ed to new master branch code and then did gpt-2/convert-h5-to-ggml.py.
But, unfortunately, rinna's gpt-2 model has no vocab.json and added_tokens.json.
So, the conversion was failed.

Original exception was:

I'm sorry for no understanding the model file's detail.
rinna's x-small model's files as follows.
