why vocab.txt and tokenizer.json not in pretrained model in huggingface ??

If I run :
tokenizer = AutoTokenizer.from_pretrained('microsoft/deberta-v2-xlarge')

get bug:
ValueError: Couldn't instantiate the backend tokenizer from one of:
(1) a tokenizers library serialization file,
(2) a slow tokenizer instance to convert or
(3) an equivalent slow tokenizer class to instantiate and convert.
You need to have sentencepiece installed to convert a slow tokenizer to a fast one.
