18.01.2021 · Unlike the BERT Models, you don’t have to download a different tokenizer for each different type of model. You can use the same tokenizer for all of the various BERT models that hugging face provides. Given a text input, here is how I generally tokenize it in projects: encoding = tokenizer.encode_plus(text, add_special_tokens = True ...
