Hi i'm trying to run the code. The command is a normal one. Python main.py.

Traceback (most recent call last):

I think it could be an error in the dataloader.py file because of the make padding function.

In the dataloader.py file you can chage this part

m_mask = [torch.ones(len(self.tokenizer.encode('question: '))),torch.ones(len(self.tokenizer.encode(' context:'))),torch.ones(len(self.tokenizer.encode('answer '))),torch.zeros(len(self.tokenizer.encode('<|endoftext|>')))]

Hi, I have the same problem. Do you know how to modify it specifically? Hope to get your reply, thank you!!!
