Hi all,
I am fine-tuning the T5 transformer for the paraphrasing task. However, after preparing the data to fine-tune T5, the process stuck, and there is no error message shows or crashes. Here is the output:

I searched online without any solution. Please help me to fix this issue.
I really appreciate any help you can provide.
