Inference problem with my lora trained checkpoint

Firstly，thank you for the incredible results of this work.

I wrote the following inference code referring to the official document load the model after training, but it reported an error TypeError: 'NoneType' object is not callable, as my model does not have a tokenizer. Why is this?

Traceback (most recent call last):
