Finetuning Pegasus for summarization task

i have been trying to fine tune Pegasus for summarization task, it worked fine without getting any error.
but when i tried to generate the summary i was getting only empty list as a output.
i am not able to figure it out, is anything wrong with my fine tuning script?

Have you had any success with this?

This is probably fixed. Give it try again and let us know.
