how to use bart on openprompt？ about openprompt HOT 3 CLOSED

You may not need to modify the transformer's BART code. Just look at what we have done for T5, we wrap the original forward function of each transformer layer with a new forward function which passes past_key_values to the original transformer forward function. What need to be done to BART will be similar (I think). However, since we haven't support bart model yet, this functionality may be postponed to one or two weeks later (After the ACL :)

Hello author，have you ever used gpt2 for prompt test？If I want to output mask after the input without textual content，it will show "IndexError:index is out of bounds for dimension with size 0". Did I write something wrong？
For example：
promptTemplate = ManualTemplate( text = '{"placeholder":"text_a"} {"mask"}' , tokenizer = tokenizer )
promptVerbalizer = ManualVerbalizer( classes = classes, label_words = { "1": ["one"], "2": ["two"], "3": ["three"] }, tokenizer = tokenizer )
