This model has not been trained on any Cantonese material. It is simply a base model in which the embeddings and tokenizer were patched with Cantonese characters. One can find the original model [gpt2-tiny-chinese](https://huggingface.co/ckiplab/gpt2-tiny-chinese). I used this [repo](https://github.com/ayaka14732/bert-tokenizer-cantonese) to identify missing Cantonese characters [My forked and modified version](https://github.com/jedcheng/bert-tokenizer-cantonese) After identifying the missing characters, the Huggingface library provides very high level API to modify the tokenizer and embeddings. ``` Download a tokenizer and a model from the Huggingface library. Then: tokenizer.add_tokens("your new tokens") model.resize_token_embeddings(len(tokenizer)) tokenizer.push_to_hub("your model name") ```
