When does this happen?
IF AutoTokenizer.from_pretrained() with a model that has a custom tokenizer.json file may produce a tokenizer that, when saved via save_pretrained(), yields a different tokenizer.json with altered normalizer and pre_tokenizer settings.
How others solved it
THEN Upgrade to the latest version of transformers (main branch) to obtain the fix. If upgrading is not possible, manually verify and reapply the original tokenizer configuration after loading.
from transformers import AutoTokenizer
hf_tokenizer = AutoTokenizer.from_pretrained("deepseek-ai/deepseek-coder-6.7b-instruct")
hf_tokenizer.save_pretrained("hf_deepseek_tokenizer/")Related patterns
