My  i just use T5 in dialogue without pretrain a language model 
I want to distill a big model to t5-base model, and the big model use bpe not sentencepiece, So the tokenizer should be load the bpe codes and the vocabs is differenct from the origin t5-base model. Therefore i am not sure about two things.
1, whether the t5 can be train in dialogue without pretrain which treat the t5 like transformer, and  i find this config (https://github.com/NVIDIA/NeMo/blob/main/examples/nlp/dialogue/conf/dialogue_config.yaml) , is it meet my demand?
2, how to set the tokenizer to use bpe codes?
