A small benchmark on the from transformers import AutoTokenizer
import time
tokenizer = AutoTokenizer.from_pretrained("facebook/nllb-moe-54b")
start = time.time();tokenizer.get_added_vocab();print(time.time()-start)
>>> 0.17021536827087402
start = time.time();{k.content: v for v, k in sorted(tokenizer.added_tokens_decoder.items(), key=lambda item: item[0])};print(time.time()-start)
