RuntimeError: where expected condition to be a boolean tensor, but got a tensor with dtype Float

I was successful in getting your code to work on my 2060 laptop after a few tweeks. I just got a tesla M40 card in and am looking at running GPT-J-6 on it using this method. To start though, I thought I'd use the same code with the GPT-NEO-2.7B model to verify that it's working OK. I got the error in the title though when I tried to run it.

Any ideas as to what's going on?
