I ran into a problem trying to run demo.py

Dear author, first of all, thank you very much for your work, but I have a problem. When I run demo.py, I get the following error
But when I delete all the contents in GELU, I will get the following error
Due to my limited level, I cannot solve the above problems. I hope to get your reply or all the friends who have made such attempts. Thank you for your patience to see my problem

Start by running demo.py and capture the full text of the reported traceback, including the location involving GELU. Compare it with the second error produced after removing GELU's contents; done means demo.py runs successfully without either error.
